| 13:07.23 | T0mW | prpplague: yeah... |
| 13:07.31 | prpplague | T0mW: any idea what to search for if i want round ones? |
| 13:07.33 | jbevren | prpplague: and its only the 6th heh |
| 13:08.00 | T0mW | prpplague: hah, I don't recall round pins |
| 13:08.04 | prpplague | T0mW: hmm |
| 13:08.24 | T0mW | prpplague: that would be for some type of military cable? |
| 13:08.29 | prpplague | T0mW: i need something i can use with .1" grid holes but i need the pins a little smaller |
| 13:09.00 | T0mW | prpplague: that's why they make 2mm stuff |
| 13:09.15 | prpplague | T0mW: that doesn't work |
| 13:09.23 | prpplague | i'm have to cut all of the pins apart |
| 13:09.32 | T0mW | prpplague: I know, holes are closer together, heh |
| 13:09.46 | T0mW | prpplague: but the pins are smaller |

| 13:10.11 | prpplague | T0mW: i have to pcb's |
| 13:10.13 | T0mW | prpplague: why don't you try straight pins? see if Donna has any |
| 13:10.18 | prpplague | T0mW: both with .1" holes |
| 13:10.24 | prpplague | T0mW: .1" spaced holes |
| 13:10.44 | prpplague | T0mW: but one of the boards, the holes are too small for a standard pin to go through |
| 13:10.59 | T0mW | prpplague: how small is too small? |
| 13:11.23 | prpplague | T0mW: .005" too small |
| 13:11.23 | T0mW | prpplague: you can use hobby drill shanks as pin guages |
| 13:11.55 | prpplague | the pins almost would fit |
| 13:12.47 | T0mW | prpplague: how about just butting the ends of the header pins on top of the pads and tack-solder them down. Why does the pins have to go through the holes? |
| 13:13.19 | prpplague | T0mW: just trying to make things easy, and thats what i did for now |
| 13:13.32 | T0mW | prpplague: if you're worried about strain relief, expoxy the connector down after soldering it |
| 13:14.02 | T0mW | prpplague: I mean, if you're going to hack the board man, hack the board, heh |
| 13:14.36 | T0mW | prpplague: what kind of board is this, where'd you get one with small holes? |
| 13:14.37 | prpplague | T0mW: well i plan on design a board |
| 13:15.36 | T0mW | prpplague: most 0.1" pins are 0.042", but, I guess you can find some that are 0.040 ... |

| 13:19.41 | T0mW | prpplague: saw that |
| 13:19.50 | prpplague | T0mW: yea, thats what i'm doing the board for |
| 13:20.06 | T0mW | prpplague: oh, that has too small holes? the perf? |
| 13:20.18 | prpplague | T0mW: no the pixter mother board |
| 13:20.23 | T0mW | ok |

| 13:21.09 | T0mW | jbevren: your webserver goes to sleep when you're not watching over it? |
| 13:21.13 | jbevren | <- has sudo access |
| 13:21.20 | jbevren | T0mW: it has a service monitor, |
| 13:21.24 | jbevren | httpd would have restarted within 10 mins |
| 13:21.28 | jbevren | but why wait :) |
| 13:22.13 | prpplague | T0mW: the headers i see have specs of a .025" square |
| 13:22.23 | prpplague | but i've also seen .030" square |
| 13:24.13 | prpplague | jbevren: so whatcha think of the board so far? |
| 13:24.26 | jbevren | lots of room to work in :) |
| 13:24.44 | prpplague | hehe |
| 13:26.47 | prpplague | T0mW: what i need is similiar to wire wrap wire headers |
| 13:27.48 | prpplague | ahh perfect - http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=104053 |
| 13:28.18 | prpplague | well i say perfect |
| 13:28.24 | prpplague | it doesn't state the pin spacing |
| 13:31.36 | prpplague | yea thats .1" |
| 13:31.41 | prpplague | that would work |
| 13:32.53 | prpplague | hehe could just use solid copper wire |
| 13:35.28 | T0mW | I use 30ga wire for misc board rework: solid core kynar wire |
| 13:35.43 | prpplague | T0mW: yea, thats a little small |
| 13:35.53 | T0mW | naw, only 0.012" |
| 13:35.53 | prpplague | T0mW: this is about 22-24 gauge |
| 13:36.15 | T0mW | prpplague: steal that from the phone company truck |
| 13:36.15 | prpplague | T0mW: standard phone wire copper fits |
| 13:36.23 | T0mW | yeha |
| 13:36.24 | prpplague | T0mW: no need i have plenty |
| 13:36.25 | T0mW | yeah |
| 13:36.49 | prpplague | just worry about the flexibility |
| 13:37.03 | prpplague | probably have to provide some mounting points |
| 13:37.18 | prpplague | T0mW: what are your thoughts on the dev board |
| 13:37.20 | T0mW | yeah, that phone company stuff is not good quality wire |
| 13:37.30 | T0mW | prpplague: does it work? |
| 13:37.42 | prpplague | T0mW: of course, i wouldn't post without it working, hehe |
| 13:37.49 | T0mW | prpplague: then it doesn't matter that it is ugly |
| 13:38.17 | T0mW | s/ugly/an ugly hack/ |
| 13:39.35 | prpplague | T0mW: but i want my my production board to be pretty |
| 13:40.14 | prpplague | T0mW: what i mean by "your thoughts" i meant about a nice arm720t devboard for under $50.00 |
| 13:40.16 | T0mW | prpplague: fwiw, build root is doing the filesystem at the wrong time. It is build the filesystem image, compressing it, then calls the linux kernel target build |
| 13:40.32 | T0mW | prpplague: a ZipIt? |
| 13:40.52 | T0mW | ZipIt is ARM720T |
| 13:41.11 | prpplague | T0mW: why is that wrong? |
| 13:41.14 | T0mW | prpplague: there is that other chip select coming off the card |
| 13:41.15 | prpplague | T0mW: i said dev board |
| 13:41.21 | jbevren | some people shouldnt be allowed to have a website |
| 13:41.37 | jbevren | I mean come on, who's dumb enough to run phpbb, much less an ancient version thereof |
| 13:42.11 | prpplague | T0mW: whats wrong with the kernel being built after the rootfs? |
| 13:42.12 | T0mW | prpplague: my kernel build makes modules and installs them into the root fs tree. But, MAKE ext2root runs before the MAKE linux |
| 13:42.32 | prpplague | T0mW: ahh then you need to add an additional depend in the kernel |
| 13:42.45 | prpplague | T0mW: kernel make file that is |
| 13:42.55 | T0mW | prpplague: or, move the filesystem build to the last item |
| 13:43.05 | prpplague | T0mW: no, don't do that |
| 13:43.13 | T0mW | "after all is said and done, we build the rom image" |
| 13:43.40 | prpplague | T0mW: "after all is said and done thats needed, we build the rom image" |
| 13:43.50 | T0mW | sort of like burning an eprom first, then compiling the code to put into the eprom |
| 13:44.02 | prpplague | T0mW: thats because it doesn't know you need it |

| 14:07.03 | prpplague | yea |
| 14:08.40 | jbevren | prpplague: Use a wiggle.c application :) |
| 14:08.44 | prpplague | there are about 6 pins i need to identify |
| 14:08.48 | jbevren | wiggle a known line, and the target line at the same time |
| 14:08.57 | jbevren | then, you can use an xor gate to identify the line |
| 14:09.08 | jbevren | line1,line2 -> xor -> scope |
| 14:09.14 | prpplague | jbevren: hmm, i didn't follow that at all |
| 14:09.22 | jbevren | ok, you know the xor function |
| 14:09.37 | prpplague | yea |
| 14:09.38 | jbevren | if you do this, and the lines wiggle differently, the scope will show a square wave |
| 14:09.49 | jbevren | if they lines wiggle the same, the scope will show tiny spikes (if any) |
| 14:10.02 | prpplague | ok so what does that tell me? |
| 14:10.21 | jbevren | so if you wiggle a known line (the control sample) and a line youre looking for, you can probe around on pads until you find a flatline on the scope :) |
| 14:10.35 | T0mW | it will show a logic low when you find the pin in question |
| 14:10.43 | jbevren | T0mW: precisely |
| 14:11.09 | T0mW | iow, no activity |
| 14:11.10 | prpplague | why is that any better than just toggling the pin at a known rate? |
| 14:11.17 | T0mW | prpplague: yeah |
| 14:11.31 | jbevren | prpplague: You could do that as well, but it might be possible to mistake a chipselect or address line |
| 14:11.35 | T0mW | prpplague: faster to ignore stuff with signals on it |

| 14:14.19 | jbevren | I was reading the uclinux port stuff for the c2500's. They had an interesting idea of using PIC in a flash rom, |
| 14:14.31 | jbevren | so you coul dexecute the code directly from the flashrom instead of copying it to ram |
| 14:15.08 | T0mW | they've done that for a few years now |

| 14:19.27 | jbevren | that aside, I for some reason never made the mental connection :) |

| 14:40.05 | jbevren | what did you use for console? |
| 14:40.08 | prpplague | just enough for me to know it was booting |
| 14:40.10 | prpplague | no console |
| 14:40.14 | jbevren | ahh |
| 14:40.20 | jbevren | so you peeked after it ran to see if it was running? |
| 14:40.25 | prpplague | yea |
| 14:40.28 | jbevren | cool |
| 14:40.36 | jbevren | should have done fbcon lol |

| 15:30.03 | jbevren | lol j/k |
| 15:30.30 | T0mW | prpplague: I wrote my own printascii to bang strings out the serial port, but printascii is cool as you can printk with it (print %0x etc.) |

| 15:40.42 | prpplague | hmm |
| 15:40.51 | prpplague | jtager isn't reporting values i would expect |
| 15:41.00 | prpplague | wonder if the mmu is causing a problem |
| 15:42.21 | chouimat | hi prpplague |
| 15:45.52 | prpplague | chouimat: hey |
| 15:53.27 | prpplague | jbevren: i hate that timeout that occurs and puts it to sleep |
| 15:57.03 | jbevren | prpplague: that's why I jumpered the calibrate button |
| 15:57.14 | jbevren | it doesnt go to sleep in calibrate mod e:) |
| 15:59.40 | jbevren | that, and the music loop doesnt run |
| 16:05.36 | prpplague | crap, can't seem to get jtag tools to work properly |
| 16:24.05 | jbevren | doh |
| 16:31.40 | prpplague | shew got that work |
| 16:32.03 | prpplague | now i need a bus driver |
| 16:33.05 | jbevren | yay |
| 16:34.54 | prpplague | not sure why jtager isn't reporting any data though |
| 16:35.05 | prpplague | jbevren: your ocd app is reporting data correct? |
| 16:37.23 | *** join/#edev mbuf (n=mbuf@59.92.58.140) |
| 16:39.22 | jbevren | yeah |
| 16:39.35 | jbevren | I used ocd to determine the address for the framebuffer to get that 16bit image uploaded, for example |
| 16:40.31 | mbuf | any idea on being a FAE? would you enjoy it if one wants to work with customers and problem solving ? |
| 16:41.00 | mbuf | or is too much harsh words from the customer? |
| 16:41.06 | jbevren | FAE? |
| 16:41.15 | mbuf | jbevren, Field Application Engineer |
| 16:41.19 | jbevren | ahh |
| 16:41.21 | jbevren | enjoy! |
| 16:41.22 | jbevren | heh |
| 16:41.41 | prpplague | jbevren: i think its because its in thumb mode |
| 16:41.45 | mbuf | jbevren, enjoy? |
| 16:42.53 | jbevren | prpplague: probably |
| 16:43.04 | jbevren | I did notice that it doesnt disassemble properly (in ocd) |
| 16:43.08 | jbevren | and I never switched ocd to thumb |
| 16:43.16 | jbevren | mbuf: enjoy the field hehe |
| 16:43.49 | tuxmaniac | mbuf> which place? |
| 16:44.04 | mbuf | jbevren, i am not one, i am only asking if anyone has any experience |
| 16:44.12 | mbuf | tuxmaniac, a generic question |
| 16:44.22 | tuxmaniac | mbuf> ah ok |
| 17:05.44 | prpplague | jbevren: ok i have openocd working |
| 17:07.57 | prpplague | jbevren: it appears that the tx0 and rx0 are configured for ssp |
| 17:08.22 | prpplague | sorry my bad |
| 17:08.34 | jbevren | cool |
| 17:08.57 | prpplague | looks to be configured gpio |
| 17:26.29 | prpplague | uart seems to be working |
| 17:41.50 | jbevren | cheer! |
| 17:41.51 | jbevren | heh |
| 17:42.20 | jbevren | that system has 128 300mhz cpu's, 76,8Gflops |
| 17:42.22 | jbevren | oop |
| 17:42.24 | jbevren | wrong window |
| 17:45.12 | prpplague | jbevren: looks like the spi port is configured |
| 17:45.27 | prpplague | not sure yet if its brought out |
| 17:45.36 | prpplague | i suspect that it is not |
| 17:46.41 | jbevren | through guesswork, I think the SPI port is attached to the Ti DAC |
| 17:46.56 | jbevren | the Ti DAC is serial, and the SPI port has a mode specifically compatible with it |
| 17:47.17 | prpplague | ahh |
| 17:47.36 | prpplague | jbevren: trying to decide how to identify these 9 pins |
| 17:47.50 | jbevren | give each one 12v and see what part of the cpu stops working |
| 17:48.37 | prpplague | hehe |
| 17:49.03 | prpplague | jbevren: btw, if you get a good halt on the processor it shouldn't go to sleep |
| 17:49.30 | jbevren | prpplague: yep |
| 17:49.36 | jbevren | but the music keeps going :) |
| 17:49.59 | prpplague | mine doesn't : |
| 17:50.00 | prpplague | :) |
| 17:50.14 | jbevren | if I enter halt in ocd, the animations stop, but the music keeps going |
| 17:50.16 | prpplague | jbevren: does your screen stop? |
| 17:50.22 | jbevren | Ive even gone so far as to disable every interrupt source I could think of |
| 17:50.27 | prpplague | ahh ok, nm, i had the volume turn down |
| 17:50.31 | jbevren | however, I didnt think to disable the SPI irq's |
| 17:50.34 | jbevren | haha |
| 17:50.36 | jbevren | nyaaa |
| 18:02.25 | prpplague | jbevren: two more pins identified |
| 18:03.35 | jbevren | woot |
| 18:03.40 | jbevren | wiki still out of space? |
| 18:06.05 | prpplague | thats just it, it isn't out of space |
| 18:06.16 | prpplague | sf.net got some quotas are something broken |
| 18:06.19 | jbevren | grumble |
| 18:06.26 | prpplague | yea |
| 18:19.32 | prpplague | ok two more identified |
| 18:20.14 | jbevren | sweet |
| 18:20.34 | jbevren | so which ones are id'd so far that we didnt already have? |
| 18:22.41 | prpplague | jbevren: well all the GPIO pins have changed of course |
| 18:22.50 | jbevren | nod |
| 18:23.00 | jbevren | I'm interested in the non-gpio functions mostly heh |
| 18:23.03 | prpplague | jbevren: so i just lack 5 now |
| 18:23.09 | prpplague | jbevren: ?? |
| 18:23.12 | jbevren | well |
| 18:23.15 | jbevren | most gpio lines can do toher things |
| 18:23.20 | jbevren | like PC7:4 |
| 18:23.22 | jbevren | <PROTECTED> |
| 18:23.31 | prpplague | jbevren: sorry say again |
| 18:23.33 | jbevren | either way, I can look em up after discovery |
| 18:23.35 | jbevren | well |
| 18:23.47 | jbevren | PC7 is gpio, and address line, or the boot config line |
| 18:23.48 | jbevren | heh |
| 18:23.54 | prpplague | and? |
| 18:24.11 | jbevren | so what do these new lines do? |
| 18:24.12 | jbevren | hehe |
| 18:24.17 | jbevren | we'll put new in quotes |
| 18:24.34 | prpplague | sorry d00d i'm confused as to what you are saying |
| 18:24.55 | jbevren | aw forget it :P |
| 18:25.02 | prpplague | hehe, no seriously |
| 18:25.10 | prpplague | jbevren: am i missing something? |
| 18:25.28 | prpplague | jbevren: are you asking what the multiplexe functions are for the gpio lines that are on the card edge connector? |
| 18:25.32 | jbevren | yeah |
| 18:25.34 | jbevren | well |
| 18:25.35 | jbevren | OH |
| 18:25.39 | jbevren | youre id'ing the cardedge? |
| 18:25.41 | prpplague | jbevren: ahh, they didn't change much |
| 18:25.44 | prpplague | jbevren: yea |
| 18:25.48 | jbevren | confusion cleared |
| 18:25.50 | jbevren | continue working :) |
| 18:33.13 | prpplague | these last 3 are gonna be hard |
| 18:39.43 | jbevren | which ones? |
| 18:44.06 | prpplague | one more done |
| 18:44.28 | prpplague | pin 52 and pin 49 |
| 18:49.19 | prpplague | hehe |
| 18:49.51 | chouimat | prpplague: glad you liked it ;) |
| 18:55.03 | prpplague | so... |
| 18:55.30 | CosmicPenguin | port kexec to busybox |
| 18:55.37 | jbevren | CosmicPenguin:) |
| 18:55.43 | CosmicPenguin | make me a really simple curses library |
| 18:55.46 | jbevren | prpplague: framebuffer console :) |
| 18:56.32 | prpplague | we have A[23..0] , D[15..0] , 1 uart, 7 gpio, 2 chip selects, and nOE/nWE |
| 18:56.39 | prpplague | jbevren: one step at a time |
| 18:57.45 | prpplague | i think my next step has to be the flash |
| 18:57.53 | prpplague | not sure if i can do much more |
| 18:58.01 | jbevren | prpplague: I'm joking :) |
| 18:58.16 | prpplague | hehe |
| 18:58.23 | prpplague | sooo |
| 18:58.29 | prpplague | what can we do with this |
| 18:58.32 | jbevren | time to hurry up and wait for the flash |
| 18:58.44 | prpplague | the 7 gpio is plenty for sd/mmc |
| 18:58.48 | jbevren | yep |
| 18:58.50 | prpplague | we can bit bang that |
| 18:59.13 | jbevren | i was reading the encj2860(?) datasheet. It notes that if you dont clock at least 8mhz, data can get corrupted |
| 18:59.22 | prpplague | sdo,sdi, sck |
| 18:59.24 | prpplague | jbevren: yea |
| 18:59.30 | jbevren | sdo, sdi, sck, cs |
| 18:59.55 | prpplague | jbevren: yea you can get away with doing some hacks for cs |
| 19:00.17 | prpplague | jbevren: technically we could wire it up on the address bus |
| 19:00.42 | jbevren | prpplague: doesnt CS have to stay asserted for the whole transfer? |
| 19:03.32 | prpplague | jbevren: yea |
| 19:03.34 | prpplague | jbevren: http://www.msx.org/forumtopic3754.html |
| 19:04.04 | prpplague | jbevren: basically just decoding a memory address |
| 19:05.02 | jbevren | nod |
| 19:05.07 | jbevren | MMIO is something I'm familiar with |
| 19:05.10 | jbevren | (c64 heritage there) |
| 19:05.52 | jbevren | hm |
| 19:05.59 | jbevren | you can do one CS per clock? |
| 19:07.01 | prpplague | jbevren: if you look the chip select is dependent on the A0 value |
| 19:07.11 | jbevren | prpplague: yeah |
| 19:07.15 | jbevren | I understand the mapping |
| 19:07.26 | jbevren | I just didnt kno wyou could deassert clk in the middle of a byte |
| 19:07.34 | jbevren | I alway spictured using a shift register |
| 19:07.36 | jbevren | ;) |
| 19:07.37 | prpplague | you can't |
| 19:07.43 | jbevren | oh? hwy not |
| 19:07.59 | prpplague | jbevren: it signals the end of the access |
| 19:08.10 | jbevren | oh, you cant deassert cs. |
| 19:08.11 | jbevren | hm |
| 19:08.16 | jbevren | m/e looks at the latches |
| 19:08.29 | prpplague | jbevren: thats a rather tricky mess |
| 19:08.42 | prpplague | ok so.... |
| 19:08.48 | jbevren | aha |
| 19:08.50 | jbevren | so |
| 19:08.55 | jbevren | writing 1 to d0 clears cs |
| 19:08.56 | prpplague | i can add two more gpios from the a/b buttons |
| 19:09.02 | jbevren | writing 0 asserts it |
| 19:09.18 | jbevren | so the latch on u3B holds CS until you deassert it |
| 19:09.28 | jbevren | Ive got it |
| 19:09.29 | prpplague | yea thats what i gather |
| 19:10.21 | jbevren | prpplague: (a0=0+rw=0) = d1 -> cs |
| 19:10.26 | jbevren | anyway |
| 19:10.26 | *** join/#edev T0mW (n=Tom@24.238.68.20.res-cmts.sth.ptd.net) |
| 19:10.40 | jbevren | I'd have used an 8bit parallel load shift register |
| 19:10.46 | jbevren | and teh reverse for readback |
| 19:10.52 | prpplague | jbevren: btw the 4 way keyoad apears to be a simple resistor ladder |
| 19:10.59 | jbevren | the c64 was my target of thought |
| 19:11.14 | T0mW | heh, thought or choice? |
| 19:11.17 | T0mW | ;) |
| 19:11.17 | prpplague | jbevren: yea since we have the full bus we could even use a standard spi controller |
| 19:11.17 | jbevren | its dotclock is precisely 8x the cpu clock, making it perfect for sending bytes out :) |
| 19:11.32 | jbevren | prpplague: there's a thought :P |
| 19:11.37 | jbevren | T0mW: hush you |
| 19:11.39 | jbevren | hehe |
| 19:11.55 | jbevren | anyway, the dotclock would clock bits into/out of the mmc |
| 19:12.20 | jbevren | since a read takes 3 cycles at least (24 dotclocks), there's plenty of time to clock the bits around |
| 19:12.57 | prpplague | T0mW: you know a good parallel interface spi master chip? |
| 19:12.58 | jbevren | a 3bit counter to count bits to clock, and two shift registers |
| 19:13.15 | *** join/#edev gandhijee (n=gandhije@mail.win-ent.com) |
| 19:13.19 | T0mW | prpplague: not an external chip, no |
| 19:13.44 | T0mW | 74194, universal shift register comes to mind |
| 19:14.09 | jbevren | a 3bit counter to count bits to clock, and two shift registers <-- |
| 19:14.10 | jbevren | :) |
| 19:14.15 | T0mW | iirc, the '194 would to parallel to serial, shift right / left |
| 19:14.45 | T0mW | iirc, it would also do serial to parallel, "universal" |
| 19:16.37 | T0mW | interesting, openwrt has a buildroot derivative that has openvpn-2.0.7 |
| 19:16.37 | T0mW | wonder if that one works |
| 19:16.37 | jbevren | afaik openwrt's openvpn works |
| 19:16.37 | T0mW | good |
| 19:16.37 | T0mW | I'm running 2.x now on the VPN |
| 19:16.49 | T0mW | 1.x had serious "issues" |
| 19:17.16 | T0mW | jbevren: would be nice to be anywhere in the world and be part of the local VPN |
| 19:17.40 | jbevren | indeed |
| 19:17.41 | T0mW | of course, VNC on the zipit *might* just pose a problem... |
| 19:17.52 | jbevren | T0mW: it does |
| 19:17.55 | jbevren | vnc -requires- 8bits |
| 19:18.01 | jbevren | I compiled vncviewer-fb |
| 19:18.03 | T0mW | heh |
| 19:18.03 | jbevren | it wouldnt run :) |
| 19:18.15 | jbevren | 3 hours toying with sources for nothing heh |
| 19:18.24 | jbevren | I'd love a RFB protocol (vnc or x) on my zipit |
| 19:18.31 | T0mW | jbevren: experience |
| 19:18.35 | jbevren | well yeah |
| 19:18.38 | jbevren | that's too true |
| 19:18.48 | jbevren | I learned more about crosscompiling with the zipit than I did on my origin |
| 19:19.03 | T0mW | jbevren: now you know something else that won't work |
| 19:19.03 | jbevren | hehe |
| 19:19.03 | T0mW | :P |
| 19:19.03 | jbevren | the vnc program does run |
| 19:19.05 | jbevren | it just hates the fb :) |

| 19:20.58 | T0mW | GPSFan: I have a working kernel, compiled on 3.4.2 |
| 19:21.15 | GPSFan | ah, good, I just read your posts on Yahoo, nice work! |
| 19:21.25 | T0mW | thank you |
| 19:21.56 | T0mW | NOW! If I can put a canned buildroot (hot load) together, maybe it will generate some more interest? |
| 19:22.17 | prpplague | hehe |
| 19:22.20 | T0mW | but, for me it is ok, now I am more interested in this thingy. heh |

| 19:23.40 | T0mW | CosmicPenguin: where have you been lurking? I haven't heard a peep out of you for days |
| 19:24.15 | T0mW | CosmicPenguin: got caught up on your honey-dos ? |
| 19:27.23 | prpplague | T0mW: have a look at the schematic here: http://www.msx.org/forumtopic3754.html |
| 19:33.23 | prpplague | T0mW: looks like the CD4094 could be used to do the same thing |
| 19:34.12 | jbevren | prpplague: you'll need to SR's. One paralle to serial, one the opposite |
| 19:34.23 | prpplague | http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=13426 |
| 19:34.29 | prpplague | jbevren: what? |
| 19:34.49 | jbevren | prpplague: the shift register you linked (I think) only goges one way |
| 19:34.58 | jbevren | that, and you have to capture DO while youre sending info to DI dont you? |
| 19:34.59 | T0mW | prpplague: where is there a CD4094 on that schematic? |
| 19:35.08 | prpplague | T0mW: there isn't |
| 19:35.17 | jbevren | T0mW: that's a bitbang interface |
| 19:35.23 | prpplague | jbevren: yea, you are right |
| 19:35.27 | T0mW | that's what I thought |
| 19:35.27 | prpplague | jbevren: i'd need two |
| 19:35.44 | T0mW | prpplague: yeah, becuase SPI can be full-duplex |
| 19:35.44 | jbevren | plus a counter to count 8 bits and wait for a read |
| 19:35.46 | jbevren | hehe |
| 19:36.05 | jbevren | that could be done with 3/4 of a 7474 though |
| 19:36.05 | prpplague | jbevren: hmm, no i don't think we need a counter |
| 19:36.26 | jbevren | you have to stop the clock after 8 bits or it'll continue throwing {undef} bits at the mmc |
| 19:36.32 | jbevren | and it'll also overflow your recieve SR |
| 19:36.36 | GPSFan | T0mW: I just put my latest (Nov 2005) patch up on Yahoo files. you might want to take a look, it has a fix for the serial port fifo problem. |
| 19:36.48 | prpplague | jbevren: "SR" |
| 19:36.50 | prpplague | <PROTECTED> |
| 19:36.52 | jbevren | shift register |
| 19:36.54 | jbevren | sorry :) |
| 19:37.03 | T0mW | IMHO, you should bit bang it. Forget about serial shifters as your overhead will be almost the same, you will have a problem trying to service a shifter running at high speed anyhow. |
| 19:37.45 | T0mW | GPSFan: ok, thanks, I've got to take a breather and then go back and "fix" buildroot so it works "right" |
| 19:37.48 | jbevren | T0mW: shrug. |
| 19:37.49 | T0mW | :P |
| 19:38.11 | jbevren | in parallel, you do 2 accesses for write and read.. in serial, you do 16 |
| 19:38.25 | jbevren | I figured that had to count for some benefit |
| 19:38.27 | jbevren | maybe not heh |
| 19:39.02 | T0mW | jbevren: problem will be stopping the register when it does the eigth bit and keeping it from overrunning the count |
| 19:39.10 | jbevren | right |
| 19:39.13 | jbevren | thus the 3bit counter :) |
| 19:39.19 | GPSFan | T0mW: I've been meaning to put that patch up for a while, you just remineded me. Go on, take a break, have a beer (or 2, 3, ...) |
| 19:39.37 | jbevren | T0mW: when you write a bit to the xmit SR, it resets the coutner, which then counts 8 times, clocking teh bits around, and stops at 0 |
| 19:39.43 | T0mW | jbevren: don't forget the glue logic (nand, nor, etc. chips) |
| 19:39.53 | T0mW | heh, do it in a CPLD |
| 19:39.57 | jbevren | T0mW: in all honesty, I'd toss .. yeah |
| 19:40.04 | jbevren | put it in a cpld :) |
| 19:40.11 | jbevren | I have an EPM7032 around here somewhere I'm sure |
| 19:40.19 | jbevren | its plenty big for a spi host |
| 19:40.32 | prpplague | T0mW: yea bit banging is easy, i was just looking at using the address/data bus since it was available |
| 19:40.33 | T0mW | CPLD as the control element, then have it murder^H^H^H^H^H^Hmanage the two shift registers |
| 19:40.52 | jbevren | T0mW: a GAL then? |
| 19:41.04 | jbevren | I was thinking something large enough to store teh two bytes and provide SR services |
| 19:41.09 | T0mW | dunno if you can still buy a GAL ? |
| 19:41.20 | CosmicPenguin | no money, no honey |
| 19:41.48 | jbevren | CosmicPenguin: we couldnt have done that better if we planned it |
| 19:42.07 | CosmicPenguin | ahh - its the little things in life that matter.. :) |
| 19:42.15 | prpplague | hehe |
| 19:42.17 | jbevren | T0mW: either way though, most PLDs these days are large enough (logically speaking) to handle being two SR's, some address decoding, and a small counter |
| 19:42.30 | T0mW | hey, stop talking about my ding-a-ling! |
| 19:43.22 | T0mW | jbevren: you'd have to go fairly dense to get two 8 bit shifters and a 3 bit counter implemented. Small FPGA perhaps |
| 19:43.33 | prpplague | CosmicPenguin: i'm serious about sending you a pixter-mm to get some nano-x going |
| 19:43.44 | CosmicPenguin | I'm serious about getting nano-x going on it too |
| 19:43.52 | jbevren | T0mW: Hrm |
| 19:44.07 | jbevren | T0mW: I'm unfamiliar with registers vs PLD density |
| 19:44.11 | T0mW | prpplague: why not, tack an LPC2101 ($3) on the board and offload your SPI work? |
| 19:44.25 | jbevren | 20 bits is too big for a small pld then I guess |
| 19:44.30 | prpplague | not familiar with the lpc2101 |
| 19:44.37 | jbevren | prpplague: arm uController |
| 19:44.38 | T0mW | ARM7TDMI |
| 19:44.42 | prpplague | hehe |
| 19:44.45 | T0mW | ARM7TDMI-S |
| 19:44.51 | jbevren | T0mW: whats -s? |
| 19:44.56 | prpplague | syntisized |
| 19:45.00 | T0mW | dunno, but it is "in there" |
| 19:45.13 | jbevren | ahh |
| 19:45.18 | jbevren | softcore |
| 19:45.20 | jbevren | now I remember |
| 19:45.21 | prpplague | yea |
| 19:45.28 | T0mW | this is one of those techno channels, I have to be accurate here |
| 19:45.37 | prpplague | hehe |
| 19:45.38 | jbevren | T0mW: :) |
| 19:45.56 | T0mW | CosmicPenguin has hall-duty today |
| 19:46.29 | jbevren | CP's the hall monitor? :) |
| 19:46.35 | T0mW | ok, off to the drug store. |
| 19:46.35 | jbevren | I didnt have hall monitors in my school |
| 19:47.48 | chouimat | arrrggggg man I hate this snmp stuff!!!! |
| 19:48.16 | CosmicPenguin | we all do, bro |
| 19:49.20 | chouimat | CosmicPenguin: the only c++ class I found is a commercial one at 5000usd ... so I guess it will be write a wrapper around net-snmp |
| 19:49.24 | prpplague | looks to see which sd/mmc slot to use |
| 19:51.45 | jbevren | heh speaking of snmp |
| 19:51.51 | jbevren | I ported tinysnmp to my zipit :) |
| 19:54.30 | jbevren | hm |
| 19:54.45 | jbevren | the sabrent usb controllers for bluetooth on surpluscomputers decidedly work in linux |
| 20:02.16 | CosmicPenguin | oh yeah |
| 20:02.17 | CosmicPenguin | they work awesome |

| 21:01.29 | jbevren | does removing the (foil lined) casing increase their range? :) |
| 21:02.03 | CosmicPenguin | heh |
| 21:02.03 | CosmicPenguin | didn't try |
| 21:02.03 | jbevren | it's a snap together case |
| 21:02.03 | jbevren | easy to open |
| 21:04.01 | jbevren | oh I love that part |
| 21:04.04 | jbevren | oop |
| 21:12.20 | jbevren | cp: which bluetooth stack do you use? |
| 21:30.21 | jbevren | aha bluez found my mouse |
| 21:30.26 | jbevren | now if I can remember how to connect to it :) |
