| 00:04.00 | jbevren | hmmhosting it on your adsl? |
| 00:04.12 | prpplague | yea |
| 00:04.15 | prpplague | 1.4 up/down |
| 00:04.20 | jbevren | I hope slashdot doesnt discover you :) |
| 00:04.25 | prpplague | i doubt i'll have much traffic |
| 00:04.34 | prpplague | who wants to look at my geeky toy hacks |
| 00:04.48 | jbevren | me :) |
| 00:09.06 | prpplague | hehe |
| 00:09.18 | jbevren | speaking of which, how gopes the pixter mm? |
| 00:09.25 | jbevren | I really need to build a proper wiggler |
| 00:10.08 | jbevren | http://linuxdevices.com/news/NS3333081612.html |
| 00:10.10 | jbevren | you know |
| 00:10.14 | jbevren | I should really go to market |
| 00:10.21 | jbevren | cause I thought of stuff like that 3-4 years ago |
| 00:11.42 | prpplague | hehe |
| 00:12.17 | prpplague | jbevren: re the url and this is new? |
| 00:12.26 | jbevren | not really heh |
| 00:12.32 | jbevren | its new to me (to see it being marketed) |
| 00:12.33 | prpplague | hehe oh i see the date |
| 00:14.06 | prpplague | jbevren: hehe look at one of my desings on linuxdevices.com and look at the date |
| 00:14.08 | prpplague | jbevren: http://www.linuxdevices.com/articles/AT3193512578.html |
| 00:14.15 | prpplague | jbevren: used the same chip |
| 00:14.24 | prpplague | jbevren: had a version to do ltsp and several other things |
| 00:14.44 | prpplague | jbevren: took me 2 solid years to design that |
| 00:15.33 | prpplague | hehe i still use this quote on my resume - "The software that's included is solid and functional. Anyone trying to build their own embedded Linux device would do well to study how Advantage put the TCSX-1's software together." |
| 00:15.53 | joe_bleau | I really dislike the font used in the silkscreen on the outside of the box. |
| 00:16.30 | jbevren | meh. I really wish I were in the mood to tinker |
| 00:16.58 | prpplague | joe_bleau: why is that? |
| 00:17.20 | joe_bleau | I dunno, something about the serifs makes it looks like some of that cheap chinese junk. |
| 00:17.32 | joe_bleau | It's odd, but I can spot it on a lot of stuff these days. |
| 00:17.38 | joe_bleau | Especially stuff from cyberguys. |
| 00:17.50 | prpplague | hehe |
| 00:17.53 | jbevren | hm |
| 00:17.59 | jbevren | I have a 66mhz stpc board |
| 00:18.11 | jbevren | its not as slow as one would expect actually |
| 00:18.14 | prpplague | joe_bleau: that box cost us $73 to make and we sold it for $400 |
| 00:18.16 | jbevren | having a 66mhz ram bus helps :) |
| 00:18.23 | joe_bleau | Nice markup. |
| 00:18.32 | prpplague | oh yea |
| 00:18.47 | prpplague | joe_bleau: i was totally betrayed by advantage |
| 00:18.48 | jbevren | see? i'm in the worng effin industry :) |
| 00:18.56 | prpplague | joe_bleau: i designed a who line of stuff |
| 00:19.01 | joe_bleau | Sorry to hear that, both of you. |
| 00:19.04 | jbevren | joe :) |
| 00:19.08 | prpplague | joe_bleau: then they decided they didn't want ot build the stuff |
| 00:19.17 | prpplague | joe_bleau: just GAVE the designs to the sub |
| 00:19.29 | jbevren | ack |
| 00:20.08 | joe_bleau | Were you a regular employee? Or were you getting royalties? |
| 00:20.34 | prpplague | regular hourly employee |
| 00:20.38 | prpplague | joe_bleau: http://www.icop.com.tw/products_category.asp?CategoryID=8 |
| 00:20.47 | jbevren | hm |
| 00:20.51 | joe_bleau | Then why does it bother you that they gave the designs to a sub? |
| 00:20.53 | prpplague | joe_bleau: i did the designs for the top 5 in that list |
| 00:21.15 | jbevren | use pxe to load the kernels for my workstations |
| 00:21.16 | jbevren | heh |
| 00:21.27 | joe_bleau | Hey, he's got x86 misery in his past! |
| 00:21.38 | prpplague | joe_bleau: bacause it was like saying "oh well your stuff is worthless to us" |
| 00:21.39 | joe_bleau | No wonder you're so hard core ARM these days. |
| 00:21.48 | jbevren | heh |
| 00:21.52 | prpplague | hehe yea |
| 00:22.07 | jbevren | arm is widespread enough that knowing it would be just plain handy |
| 00:22.09 | joe_bleau | Gotta ignore that stuff. You did your job, you got paid. Let them screw it up. |
| 00:22.28 | prpplague | joe_bleau: yea well i poor my soul into my work |
| 00:22.37 | prpplague | joe_bleau: not the same for the PHB's |
| 00:22.47 | jbevren | I do less and less, but thats a subject best left undiscussed :) |
| 00:23.55 | joe_bleau | What do y'all make of the buzz around the clockless or async stuff lately? Think it's gonna be vapor, or turn real one of these days? |
| 00:24.22 | prpplague | joe_bleau: not sure yet |
| 00:25.29 | jbevren | prpplague: you were pointing out a 128x64 lcd at bgmicro |

| 00:30.11 | jbevren | crazy people |
| 00:30.23 | prpplague | the ones at sparkfun are basically the exact same, just a 1/4" smaller |
| 00:30.30 | jbevren | ahh |

| 00:32.43 | prpplague | ahh |
| 00:32.44 | jbevren | its a possible side effect of neurofeedback training |
| 00:32.51 | prpplague | really? |
| 00:32.57 | jbevren | I guess so |
| 00:33.06 | jbevren | it's listed in the openEEG warning file |

| 00:35.53 | prpplague | joe_bleau: yea i really like the color lcd just too small |
| 00:36.06 | joe_bleau | Too bad, it's cheap and nice. |
| 00:36.31 | joe_bleau | I guess if it were twice the size, they wouldn't be selling it so cheap. |
| 00:36.56 | jbevren | no doubt |
| 00:37.09 | jbevren | I think its just cheap cause they overmanufactured so badly |
| 00:37.39 | joe_bleau | Well, it sucks to be them then! |
| 00:37.44 | joe_bleau | Nice for us, though. |

| 16:21.54 | jbevren | its a microcontroller |
| 16:21.59 | jbevren | just make it appear as a serial port or something :) |
| 16:22.45 | jbevren | hm or does the uc not talk directly to usb |
| 16:23.05 | Chocobo | Alright, I could easily open up a fd to it... I wonder what the protocol it uses... |

| 17:22.09 | prpplague | T0mW: are you alive or what???? |
| 17:26.14 | T0mW | prpplague: yeah, just got the circuit boards in and was checking some of the mechanical stuff |
| 17:26.21 | prpplague | T0mW: hey |
| 17:26.26 | prpplague | T0mW: need some advice |
| 17:26.56 | T0mW | prpplague: got lots of that |
| 17:27.25 | prpplague | http://pastebin.com/685301 |
| 17:27.38 | prpplague | T0mW: i need two more lines to complete the lcd driver data lines |
| 17:27.46 | prpplague | T0mW: i've got to cut two lines |
| 17:27.51 | prpplague | T0mW: question is which two |
| 17:28.03 | prpplague | T0mW: either get rid of the second uart |
| 17:28.15 | prpplague | T0mW: or maybe get rid of the control lines for uart0 |
| 17:31.10 | T0mW | I would keep the control lines for the UART, definately better that you have no second UART as opposed to having two crippled ones. |
| 17:31.32 | prpplague | T0mW: yea |
| 17:31.34 | T0mW | prpplague: however, I would perhaps put a cut & jumper on the PCB to connect the RTS/CTS lines to the TXD/RXD of the second UART. leave it as an option |
| 17:31.53 | prpplague | T0mW: hmm, board is way too small to do that |
| 17:31.55 | T0mW | you already have the RS232-C level shifters on those pins... |
| 17:31.59 | prpplague | T0mW: but i think i found a way |
| 17:32.24 | T0mW | prpplague: you don't have to make it BIG, just run some vias close to each other. |
| 17:32.30 | prpplague | T0mW: get rid of pins 8 and 11 |
| 17:32.49 | prpplague | T0mW: that makes the spi master only |
| 17:33.00 | prpplague | T0mW: and just gets rid of one additional eint |
| 17:33.45 | prpplague | T0mW: whatcha think? |
| 17:34.22 | prpplague | T0mW: its not pin for pin right now, just figureing out what to have available |
| 17:35.11 | T0mW | I dunno, depends on the app, master/slave mode of the SPI might be more usefull than the second UART? |
| 17:35.47 | prpplague | T0mW: but you need two master/slave spi's on one device? |
| 17:36.42 | T0mW | huh? |
| 17:36.59 | T0mW | ?? " but you need two master/slave spi's on one device" |
| 17:38.14 | T0mW | not sure of the processor, but on the LPC2000, one is an SSI the other is an SPI (SSI is much faster than SPI, but essentially the same). |
| 17:38.16 | prpplague | T0mW: i am asking, do you really need two master/slave spi controllers on one device |
| 17:38.38 | T0mW | not really |
| 17:39.23 | T0mW | I have one internal to the PCB to run internal stuff, then use the other to interface externally. If you have no internal SPI stuff, then lose one of them |
| 17:39.28 | prpplague | which is why i got ride of the control for that |
| 17:39.54 | prpplague | T0mW: well i was gonna keep both spi's just remove the option for one of them to be used as a slave |
| 17:40.38 | T0mW | you could do that |
| 17:40.48 | T0mW | nothing serious, just a limitation |
| 17:50.34 | jbevren | doh :( |
| 18:01.58 | prpplague | T0mW: http://pastebin.com/685383 |
| 18:03.22 | prpplague | T0mW: whatcha think? |
| 18:33.18 | Chocobo | Is JTAG a standard protocol or is it different for each chip? |
| 18:34.06 | jbevren | it's standard, but not all chips have the same circuitry, so you need an information file for each IC |
| 18:34.49 | Chocobo | Ok, cool. Hrm, has any good JTAG resporces off the top of your head? |
| 18:36.10 | jbevren | not myself, no |
| 18:36.13 | jbevren | I'm about as new to it as you :) |
| 18:37.55 | prpplague | Chocobo: http://www.elinux.org/wiki/JTAG |

| 19:03.44 | jbevren | I have one myself heh |
| 19:03.47 | prpplague | not me |
| 19:04.02 | prpplague | jbevren: but i do like the .1" proto pcb's |
| 19:04.03 | T0mW | jbevren: yeah, the kind that JameCo sells? |
| 19:04.09 | jbevren | tom: right |
| 19:04.14 | T0mW | LOL |
| 19:04.24 | T0mW | wish I had one of those for SMD parts |

| 19:04.48 | prpplague | T0mW: schmit;s don't work for you? |
| 19:04.58 | jbevren | T0mW: that would rock :) |
| 19:05.40 | T0mW | jbevren: solderless, tiny little locking clamps to hold the body of the smd down |
| 19:05.50 | T0mW | ... spring loaded |
| 19:05.56 | jbevren | how about a vaccuum table to hold the devices against pads |
| 19:05.58 | jbevren | hehe |
| 19:06.05 | jbevren | man that'd suck |
| 19:06.05 | T0mW | lol yeah BTDT |

| 19:06.37 | prpplague | T0mW: i love those |
| 19:06.43 | jbevren | prpplague: use any yet? |
| 19:06.47 | jbevren | its a very cool concept |
| 19:06.58 | T0mW | prpplague: FTS |
| 19:07.02 | jbevren | I want a bga schmartboard that you bake in the oven hehe |
| 19:07.04 | prpplague | jbevren: yea tried some a couple of months ago |
| 19:07.06 | prpplague | T0mW: ? |
| 19:07.16 | T0mW | Fsck That Sh!t |
| 19:07.20 | prpplague | T0mW: oh |
| 19:07.46 | T0mW | I've looked at those before, they are "interesting" |
| 19:07.50 | prpplague | hehe |
| 19:08.12 | T0mW | they remind me of a spinoff on "dead bug" prototyping |
| 19:08.27 | jbevren | hehe |
| 19:08.36 | jbevren | I'd like to see someone deadbug a .5mm chip |
| 19:08.47 | T0mW | first you take a blank copper board, then with your dremel... |
| 19:08.48 | jbevren | I tried deadbugging an atmel arm IC once |
| 19:08.55 | jbevren | I could never get the wires onto the bga pins right |
| 19:09.24 | T0mW | jbevren: microscope, then use xacto to alternately bend leads downward. |
| 19:09.27 | prpplague | T0mW: something like this one - http://www.ramtex.dk/tinyarm/tinyarm.jpg |
| 19:09.27 | jbevren | I hotglued it upside down to a perfboard and got two rows of wires done before it became unmanageable :) |
| 19:09.36 | jbevren | T0mW: aha. good idea :) |
| 19:09.37 | prpplague | T0mW: just with a better arm chip |
| 19:10.06 | jbevren | couple megs of flash, a handful of ram |
| 19:10.20 | jbevren | <PROTECTED> |
| 19:10.25 | T0mW | why bother, build a real board and then you have lots of pins available? |
| 19:10.39 | jbevren | T0mW: that becomes a $200 board that keeps hobbyists away |
| 19:10.54 | jbevren | I can see the reasoning, |
| 19:11.06 | jbevren | I used to live on peanuts, and wanted to work with stuff like this |
| 19:11.19 | jbevren | but I couldnt afford the dev boards, even used at $200 |
| 19:11.32 | jbevren | sparkfun has some cool lpc boards now though |
| 19:11.39 | T0mW | one thing that I learned from selling the MP100 Ham Radio Repeater Controller boards: no hobbist wants to spend more than $40 for something |
| 19:11.54 | prpplague | hehe |
| 19:11.57 | jbevren | yeah |
| 19:12.05 | jbevren | although if its a good board, I'd consider it |
| 19:12.15 | jbevren | like that arm board that keeps floating across ebay |
| 19:12.24 | T0mW | It was quieter than an SCOM 7K |
| 19:12.27 | prpplague | jbevren: which on is that? |
| 19:13.27 | jbevren | sec |
| 19:13.30 | jbevren | I linked you once or twice |
| 19:13.33 | jbevren | az4510 |

| 19:13.35 | jbevren | ax4510 |
| 19:13.45 | jbevren | 7593066148 |
| 19:13.49 | jbevren | cant get myself to buy one yet |
| 19:14.07 | jbevren | its largeish, but h as all the connectors at edges, and has all the cpu pins on solder pads |
| 19:15.05 | prpplague | thats not a very good choice |
| 19:15.19 | prpplague | jbevren: you can get a 44b0x board for $100 |
| 19:15.22 | jbevren | that's not what SHE said (joking) |
| 19:15.28 | jbevren | hm url? |
| 19:15.42 | jbevren | I think you gave that url to me, but cant find it |
| 19:16.17 | prpplague | http://anyway.no-ip.org:8080/ep/44B0db/44B0db.htm |
| 19:16.20 | prpplague | much better choice |
| 19:16.22 | T0mW | jbevren: what is that thing? 10" X 5" ? |
| 19:16.31 | prpplague | you can even use the the juicebox lcd with it |
| 19:17.18 | T0mW | prpplague: ooo! It has a buzzer on it! |
| 19:17.27 | prpplague | hehe |
| 19:17.48 | jbevren | hehe |
| 19:17.57 | T0mW | All my PCBs have a buzzer and glittering LEDs! |
| 19:18.09 | T0mW | plus an "ACK" button |
| 19:18.33 | prpplague | T0mW: http://www.giantplus.com.tw/22-lcd_module_gpg24164is1.html |
| 19:18.39 | prpplague | T0mW: look at that pinout for me |
| 19:18.39 | jbevren | is the ack button for crashes? |
| 19:18.42 | jbevren | ACK! IT CRASHED! |
| 19:18.48 | prpplague | T0mW: something confusing for me with that |
| 19:18.57 | prpplague | T0mW: they have pins for v0~v7 |
| 19:19.00 | T0mW | "ACK somebody broke into the warehouse" |
| 19:19.02 | jbevren | prpplague: where are these sold? :) |
| 19:19.14 | jbevren | thats what I remember, I never found a store or info on who to contatct for sales |
| 19:19.24 | prpplague | T0mW: but they also have also have duplicate pins for v2-5 |
| 19:19.28 | T0mW | prpplague: hey! that looks like the ZipIt lcd! |
| 19:19.38 | prpplague | T0mW: naw its color |
| 19:20.33 | prpplague | jbevren: Item number: 7597772435 |
| 19:21.33 | prpplague | wow check out this one - http://cgi.ebay.com/S3CEV40-Evaluation-Board-A-with-LCD_W0QQitemZ7576623892QQcategoryZ73154QQssPageNameZWD1VQQrdZ1QQcmdZViewItem |
| 19:21.59 | T0mW | prpplague: damned close! |
| 19:22.05 | prpplague | T0mW: ?? |
| 19:22.11 | prpplague | T0mW: oh yea |
| 19:22.18 | prpplague | T0mW: they have some grey scale ones too |
| 19:22.27 | prpplague | T0mW: any clue on those pins? |
| 19:22.28 | T0mW | prpplague: all signals are there for the ZipIt. |
| 19:22.42 | T0mW | prpplague: I've fully reverse engineered the zipit |
| 19:22.51 | prpplague | T0mW: you recon they might be a 1/2 color mode? |
| 19:23.03 | T0mW | prpplague: didn't bother with reversing the Wifi electronics though |
| 19:23.40 | T0mW | prpplague: IIRC, the EP7312 can do color LCD, I'll check that |
| 19:23.49 | prpplague | T0mW: okie gokie |
| 19:24.15 | prpplague | T0mW: _what_ about those duplicate pins??????????? |
| 19:24.23 | T0mW | yeah |
| 19:24.31 | T0mW | duplicate pins? |
| 19:24.41 | prpplague | T0mW: look at the pin out on the page |
| 19:24.56 | prpplague | T0mW: the pinout has a set for V0 thru V7 |
| 19:25.09 | prpplague | T0mW: but it also specifically lists pins V2 V3 V4 and V5 |
| 19:25.34 | T0mW | nm, pins 9-16 are not on ZipIt |
| 19:25.51 | T0mW | ZipIt is 4 bit data |
| 19:25.55 | prpplague | T0mW: right |
| 19:26.24 | prpplague | T0mW: which makes me think you probably could run this lcd in a 16 color mode |
| 19:26.36 | jbevren | it has 16 greys already (?) |
| 19:26.50 | jbevren | in the worst case, you could use a small CLUT :) |
| 19:26.57 | prpplague | clut? |
| 19:27.01 | jbevren | color look-up table |
| 19:27.13 | jbevren | it would have 16 entries (four bits) and color outputs |
| 19:27.18 | jbevren | basically a non-dac ramdac |
| 19:28.03 | prpplague | oh |
| 19:28.44 | jbevren | unless youre thinking of a CGA/RGBI-style colorset on the lcd (?) |
| 19:29.34 | T0mW | prpplague: the ZipIt has +3.3v and four other positive voltage levels feeding the LCD |
| 19:30.06 | prpplague | T0mW: right, thats gonna be the bias, vline, vframe, and vclock |
| 19:30.27 | jbevren | the zipit lcd is passive then? |
| 19:30.28 | prpplague | T0mW: then the 4-bit data |
| 19:30.47 | jbevren | I never looked that close at the lcd :) |
| 19:33.12 | T0mW | prpplague: www.openhardware.net/ZipIt-sheet2.pdf |
| 19:33.31 | T0mW | prpplague: it will be gone in a few minutes, don't want that hanging around |
| 19:34.07 | T0mW | got it? |
| 19:34.16 | prpplague | dang it no |
| 19:34.17 | prpplague | one sec |
| 19:34.43 | prpplague | ok done |
| 19:34.44 | jbevren | T0mW: I couldnt talk you out of the whole set could I? :) |
| 19:35.04 | T0mW | ~jbevren |
| 19:35.22 | T0mW | purl: you awake? |
| 19:35.31 | T0mW | ~kick purl |
| 19:35.32 | purl | bugger off sod! |
| 19:35.33 | T0mW | heh |
| 19:35.34 | jbevren | nono |
| 19:35.36 | jbevren | <PROTECTED> |
| 19:35.39 | jbevren | see? :) |
| 19:35.49 | prpplague | T0mW: yea thats all pretty standard STN 4-bit greyscale |
| 19:35.57 | T0mW | jbevren: you got email? |
| 19:36.09 | jbevren | yeah, privmsg |
| 19:36.59 | jbevren | hm |
| 19:37.03 | jbevren | I wondered how the power switch worked :) |
| 19:41.13 | T0mW | jbevren: pretty interesting, the power switch pulls the power on, then the LPC900 grabs the same line to hold it on. |
| 19:41.25 | jbevren | nod |
| 19:41.35 | jbevren | sort of an "I'm awake and will keep myself awake" thing |
| 19:41.50 | T0mW | LPC900 monitors the switch to see when you signal to shut off the power |
| 19:41.52 | jbevren | I like the use of the RC circuit to create the fading lamp |
| 19:42.11 | jbevren | no, thats not what fades the lamp |
| 19:42.13 | jbevren | I'm dumb today :) |
| 19:42.45 | T0mW | they probably stutter the LED |
| 19:42.55 | jbevren | pwm yeah |
| 19:43.00 | T0mW | yeah |
| 19:43.25 | T0mW | pretty simple design really |
| 19:44.05 | T0mW | sorphin is not here so we can talk "ZipIt" |
| 19:44.28 | jbevren | heh |
| 19:44.33 | jbevren | he can just minimize his irc window mwahaha |
| 19:47.36 | T0mW | prpplague: I put a magjack + ENC28J60 on this new board |
| 19:47.51 | T0mW | prpplague: just to play with it |
| 19:51.51 | T0mW | prpplague: I solved my mini-JTAG connection problem by building a 2X5 dual row connector of 0.020" holes on 0.05" centers. I'll solder 30ga wire into the holes and then wire them to a 0.1" header to have the BDI2000 plug into that. |
| 19:51.53 | prpplague | T0mW: got it working yet? |
| 19:52.09 | T0mW | prpplague: naw, paste stencil will come tomorrow |
| 19:53.12 | T0mW | prpplague: there is a ton of 0805 resistors + caps on this board, plus, a couple of SSOP devices and a LQFP |
| 19:54.08 | T0mW | I don't even want to try using the pneumatic syringe to paste this board |
| 19:55.44 | T0mW | just for giggles, I put "cut me" near a cut & jumper point in 0.032 text. It is legible! |
| 19:56.10 | T0mW | I was curious as to how small you could make the silk text |
| 19:56.15 | prpplague | hehe |
| 19:57.11 | jbevren | ncs2 leads to a via? heh |
| 19:57.32 | T0mW | yes, interesting |
| 19:57.54 | T0mW | jbevren: I've located those two on my website. |
| 19:58.12 | jbevren | nod. I'll have a browse in a moment. :) I have to make it at least appear that I'm working :) |
| 19:58.15 | T0mW | they are accessible from the bottom of the PCB under the keyboard |
| 19:59.23 | T0mW | http://www.openhardware.net/?title=ZipIt%20VIAs&dir=zipit&file=zipitVias.html |
| 20:00.03 | jbevren | what are the 'drive' lines for? (out of curiosity) |
| 20:03.59 | prpplague | T0mW: http://www.allelectronics.com/cgi-bin/item/LCD-103/365/640_X_400_LCD_DISPLAY_W__EL_BACKLIGHT_.html |
| 20:04.17 | prpplague | T0mW: can i pester you with a question on the datasheet for that? |
| 20:06.10 | jbevren | heh |
| 20:06.18 | jbevren | do you make a carreer out of scanning these sites prp? :) |
| 20:06.28 | jbevren | (note: I dont make one by spelling correctly) |
| 20:06.39 | prpplague | jbevren: my job to research items |
| 20:06.56 | jbevren | ah, so you do ;-) |
| 20:07.07 | jbevren | I think I have an lcd like this |
| 20:09.09 | prpplague | that lcd is kinda power hungry though |
| 20:09.40 | jbevren | afk, lunch |
| 20:10.20 | T0mW | prpplague: that is a dual display (DSTN), not an STN |
| 20:12.00 | T0mW | looks like they load both nibbles (upper & lower) on the single load pluse |
| 20:12.07 | T0mW | pulse even |
| 20:12.23 | T0mW | s/pluse/pulse/ |
| 20:12.45 | prpplague | T0mW: yea |
| 20:13.00 | prpplague | T0mW: question was about the ratings |
| 20:13.29 | prpplague | T0mW: from what i am reading it should be capable of being used with 3.3v inputs |
| 20:13.33 | prpplague | T0mW: thats correct? |
| 20:14.19 | prpplague | T0mW: it shows a high level as being 0.8Vdd to Vdd |
| 20:14.26 | prpplague | T0mW: where Vdd should be 5v |
| 20:14.27 | T0mW | no, 0.8VDD is 4volts |
| 20:14.44 | prpplague | ok so thats 0.8*Vdd |
| 20:14.52 | T0mW | right |
| 20:14.59 | prpplague | ok thats what i was wondering |
| 20:15.10 | T0mW | level shifter time |
| 20:15.32 | T0mW | something like LVT logic with +5v pullups |
| 20:15.36 | prpplague | right |
| 20:15.42 | prpplague | T0mW: i was just checking |
| 20:15.50 | prpplague | T0mW: i don't plan to use that one anyway |
| 20:16.00 | prpplague | T0mW: trying to understand limitations and such |
| 20:16.11 | prpplague | T0mW: that one is way too power hungry for me |
| 20:17.23 | T0mW | heh, my youngest brother is buying hisself a new mustang muscle car |
| 20:17.28 | prpplague | hehe |
| 20:17.38 | T0mW | He lives in Alabama |
| 20:17.45 | prpplague | i wish i could find someone to buy my tiburon-gt |
