| 01:13.54 | T0mW | prpplague: hello |
| 01:14.08 | prpplague | T0mW: spent the day learning eagle |
| 01:14.22 | prpplague | T0mW: running autorouter on a test board now |
| 01:14.51 | T0mW | prpplague: I spent the day cleaning up the burn3 source for the ZipIt |
| 01:15.02 | prpplague | hehe |
| 01:15.10 | prpplague | T0mW: well, lots of traces to run |
| 01:15.14 | T0mW | it works good now |
| 01:15.22 | prpplague | T0mW: nor sure i can do it with a 2 layer board |
| 01:15.34 | T0mW | is it BGA? |
| 01:15.50 | prpplague | hehe, no |
| 01:15.59 | T0mW | then you can do it in two layers |
| 01:16.03 | prpplague | hehe |
| 01:16.15 | T0mW | some boards take longer than others |
| 01:16.27 | T0mW | BTW, autorouters suck |
| 01:16.30 | prpplague | T0mW: what auto router settings do you use? |
| 01:16.33 | prpplague | T0mW: yea |
| 01:16.36 | T0mW | I don't |
| 01:16.41 | T0mW | I don't use it |
| 01:17.16 | prpplague | ahh |
| 01:18.44 | prpplague | thats just a lot of signals to route |
| 01:23.14 | MonMotha | prpplague: what layout software are you using? |
| 01:23.20 | MonMotha | eagle? |
| 01:24.44 | prpplague | yea |
| 01:24.56 | MonMotha | ok, not familiar with that |
| 01:25.00 | MonMotha | I usually use OrCAD |
| 01:25.08 | MonMotha | autorouter still sucks, but the DRC is awesome |
| 01:25.08 | prpplague | MonMotha: www.cadsoft.de |
| 01:25.18 | prpplague | MonMotha: they have a "lite" version for linux |
| 01:25.20 | MonMotha | I've used eagle |
| 01:25.22 | prpplague | MonMotha: free |
| 01:25.30 | MonMotha | OrCAD is free for me atm |
| 01:25.35 | MonMotha | I do prefer it to eagle |
| 01:25.46 | prpplague | <MonMotha> ok, not familiar with that |
| 01:25.58 | prpplague | hehe i must have misunderstoof |
| 01:26.08 | MonMotha | I've used it, but not enough to be very familiar with it |
| 01:26.13 | prpplague | T0mW: traces between .1" pins |
| 01:26.20 | prpplague | T0mW: any problems doing that? |
| 01:26.23 | MonMotha | if you were using OrCAD, I coudl probably get a few hints on tweaking the autorouter |
| 01:26.33 | T0mW | sure, traces between 0.05" pins too |
| 01:26.36 | MonMotha | prpplague: every board I've mad has had traces between .1" pins, works fine |
| 01:28.57 | prpplague | T0mW: i'm using 10 mil traces |
| 01:29.02 | prpplague | T0mW: what about the vias? |
| 01:29.05 | prpplague | MonMotha: ahh ok thanks |

| 01:35.44 | prpplague | T0mW: is there a way to hide some of the ratsnest? |
| 01:36.06 | T0mW | now |
| 01:36.13 | T0mW | all or nothing |
| 01:36.26 | T0mW | prpplague: that's why they call it a ratsnest |
| 01:37.53 | T0mW | the ZipIt addon board works fine |
| 01:39.41 | chouimat|ibook | clercks 2?????? |
| 01:39.56 | prpplague | T0mW: cool |
| 01:40.05 | prpplague | T0mW: oh i remeber what i needed to ask |
| 01:40.12 | chouimat|ibook | hi T0mW MonMotha prpplague |
| 01:40.14 | prpplague | T0mW: through hole resistors |
| 01:40.18 | prpplague | chouimat|ibook: evening |
| 01:40.39 | prpplague | T0mW: which pne to use for just a standard 1/4 watt through hole? |
| 01:40.55 | T0mW | well, 207 |
| 01:41.06 | chouimat|ibook | night ;) |
| 01:41.11 | T0mW | you can measure parts in the layout |
| 01:42.10 | prpplague | hehe, yea i have nothing to measure with |
| 01:42.21 | prpplague | getting a caliper tomorrow |
| 01:42.38 | T0mW | there is an icon call "mark", that sets a relative measureing point. relattive distances are in parenthesis follow the true measurement values (next to the command line). |
| 01:43.08 | T0mW | prpplague: I use peice of 0.1" perf to do rough measurements |
| 01:44.02 | prpplague | ahh |
| 01:45.01 | T0mW | usually 0.4" lead centers for 1/4 horizontally mounted is fine |
| 02:10.15 | prpplague | T0mW: weird i have a couple of connections where the airwire doesn't show up |
| 02:11.32 | T0mW | you may "think" you made a connection in the schematic, try moving the part in the schematic and see if all the wires rubberband or if one or two don't move |
| 02:12.30 | T0mW | prpplague: just because they look connected doesn't mean that they are |
| 02:13.32 | T0mW | prpplague: one way to screw up a connection is to put a part pin onto an existing wire (e.g. drop a part onto a wire end). You have to put a wire to a pin, not a pin to a wire. |

| 14:34.25 | jbevren | good moaning. |
| 14:34.53 | prpplague | jbevren: hey |
| 14:35.05 | prpplague | jbevren: question for ya |
| 14:35.25 | prpplague | jbevren: what exactly do _you_ want to do with your pixtermm stuff? |
| 14:35.34 | jbevren | shrug hehe |
| 14:35.36 | prpplague | jbevren: i'm designing some stuff, and was curious |
| 14:35.38 | jbevren | tinker? :P |
| 14:35.54 | jbevren | I do want to toss on a NIC and do a simple embedded remote display |
| 14:36.56 | prpplague | jbevren: having it in the case important? |
| 14:37.44 | jbevren | not horribly |
| 14:39.09 | prpplague | jbevren: so if you had a board you could attach the main pixter-mm motherboard to, would that be good? |
| 14:39.53 | jbevren | yeah |
| 14:40.00 | jbevren | it'd be handy for development for sure |
| 14:40.57 | prpplague | jbevren: yea i'm trying to decide on what direction i want to go with the dev board |
| 14:41.12 | jbevren | nod |
| 14:41.40 | jbevren | something with a handful of flash (enough to hold a kernel at least) and some bulk storage (same flash?) would be perfect |
| 14:41.45 | jbevren | beyond that, I dunno |
| 14:43.43 | prpplague | jbevren: what i was looking at was, 5v power, rs-232 uart, nor flash chip, sd/mmc socket, jtag header and a header for a enc28j60 board |
| 14:43.49 | jbevren | oh, duh |
| 14:43.53 | jbevren | yeah, uart and header hehe |
| 14:44.36 | prpplague | jbevren: what i can't decide is if i want to move all the external parts, i.e. the audio, power switch, reset, and buttons onto the board too |
| 14:44.48 | jbevren | ah, depopulate the board? |
| 14:44.58 | jbevren | oh hey, sdram q for you. |
| 14:45.07 | jbevren | are there enough lines extended to add more mem (say, 32Mbit chips)? |
| 14:45.11 | jbevren | er 128Mbit I think |
| 14:45.21 | prpplague | jbevren: yea, basically what you would do, is desolder all the connections, then just drop the board ontop of the dev board and solder into place |
| 14:45.48 | prpplague | jbevren: yes they are extended but the pads for the current chip won't work |
| 14:46.01 | *** join/#edev tuxmaniac (n=aanjhan@unaffiliated/tuxmaniac) |
| 14:47.59 | jbevren | right |
| 14:48.01 | jbevren | wrong order |
| 14:48.05 | jbevren | that I thought about |
| 14:48.16 | jbevren | I was just wondering if there are enough addressing lines |
| 14:48.18 | prpplague | jbevren: ?? |
| 14:48.23 | prpplague | jbevren: ahh, ok |
| 14:48.28 | prpplague | jbevren: yea there are enough |
| 14:49.51 | prpplague | jbevren: what do you think ? |
| 14:50.00 | prpplague | jbevren: go with all the external stuff onboard? |
| 14:50.09 | jbevren | hm |
| 14:50.11 | jbevren | clarify external stuff |
| 14:50.20 | jbevren | you mean the added hardware to be put on the dev board? |
| 14:50.21 | prpplague | jbevren: what i can't decide is if i want to move all the external parts, i.e. the audio, power switch, reset, and buttons onto the board too |
| 14:50.33 | jbevren | ohh |
| 14:50.39 | jbevren | I wouldnt move items from the pixter board |
| 14:50.44 | jbevren | but that's just me :) |
| 14:50.55 | prpplague | jbevren: whys that? |
| 14:51.03 | jbevren | if youre going that far, just get a sharm mcu and dev up a board for it :) |
| 14:51.39 | prpplague | jbevren: yea, well, its not that easy to do the board layout for that plus the cost of the lcd and touch screen |
| 14:51.48 | jbevren | too true |
| 14:51.49 | prpplague | jbevren: basically just doing dev motherboard |
| 14:51.58 | jbevren | but you could retrofit it to fit pixter parts mwahhaa |
| 14:52.08 | jbevren | anyway, on a more serious note |
| 14:52.17 | jbevren | The parts work on the pixter-mm board |
| 14:52.22 | jbevren | and I'm a fan of not fixing what's not broken |
| 14:52.41 | jbevren | it also simplifies assembly for people like me with little to no experience in SMT rework |
| 14:52.53 | prpplague | jbevren: SMT? |
| 14:52.59 | prpplague | jbevren: no smt involved |
| 14:52.59 | jbevren | surface mount tech |
| 14:53.11 | jbevren | what are you pulling off the pixter board then? |
| 14:53.16 | jbevren | I guess I still need clarification :) |
| 14:53.21 | jbevren | no IC's? |
| 14:53.23 | prpplague | jbevren: standard thru hole solder points |
| 14:54.02 | prpplague | jbevren: you can desolder all the connections in 10 minuites |
| 14:54.56 | jbevren | ahh |
| 14:55.06 | jbevren | so youre just looking at pulling the cables that extend to the pixter's body? |
| 14:55.28 | prpplague | yea, i.e. the reset button would be on the new board |
| 14:55.34 | jbevren | ok, now I'm clear |
| 14:55.37 | jbevren | that's not a bad idea |
| 14:55.39 | prpplague | as well as the speaker and the 6 buttons |
| 14:55.51 | jbevren | since most are already extended via cabling, you can just design tie points in |
| 14:56.23 | prpplague | you mean use the existing components? |
| 14:56.27 | jbevren | naw, |
| 14:56.33 | jbevren | instead of removing the cable from the pixter board, |
| 14:56.40 | jbevren | remove it from (for example) the power switch board |
| 14:56.52 | prpplague | ahh |
| 14:56.54 | jbevren | and then solder this cable to a set of pads on the devel board that are laid out to match the cable :) |
| 14:57.25 | prpplague | jbevren: yea, what i was thinking is you have the motherboard with pins sticking up |
| 14:57.42 | prpplague | jbevren: you just drop the board on top and it slides into all the holes |
| 14:57.47 | prpplague | jbevren: just solder together? |
| 14:58.38 | jbevren | that would be cool indeed |
| 14:58.50 | jbevren | the offset pins as used in the palmcam |
| 14:59.24 | prpplague | jbevren: ?? |
| 14:59.28 | prpplague | offset pins? |
| 14:59.40 | jbevren | the palmpix from kodak uses .100"-centered riser pins |
| 14:59.48 | jbevren | I'm sure youve seen them before.. |
| 14:59.58 | jbevren | anyway, its used to hook the palmpix to the palm serial connector |
| 15:00.14 | jbevren | I removed the connector from one of the cams to make a handy serial cable for my palm ;-) |
| 15:00.21 | prpplague | ahh gotcha |
| 15:00.58 | jbevren | brb |
| 15:01.01 | jbevren | pulling my fibre NIC |

| 15:17.52 | prpplague | jbevren: so anyway |
| 15:18.07 | prpplague | jbevren: like i said, i was thinking of putting all the external stuff on the board |
| 15:18.19 | prpplague | jbevren: just drop the pixter main board ontop and solder in place |
| 15:18.25 | prpplague | jbevren: whatcha think? |
| 15:18.35 | jbevren | sounds very cool |
| 15:18.38 | prpplague | jbevren: too ambicious? |
| 15:18.49 | jbevren | well, the pixter board isnt that large |
| 15:18.57 | jbevren | and it doesnt have that many pins to connect :) |
| 15:19.08 | jbevren | the only question left is what are you doing with the cartridge slot |
| 15:19.11 | prpplague | i mean design wise |
| 15:19.17 | prpplague | jbevren: removing it |
| 15:19.35 | jbevren | design-wise, it should be simple enough |
| 15:19.39 | prpplague | jbevren: those would also mate with the main board |
| 15:21.03 | jbevren | ah ok |
| 15:22.07 | prpplague | jbevren: or instead of putting all this on the board, do you think i should just bring everything out to a nice .1" headers? |
| 15:24.37 | jbevren | so at this point youre debating between adding the joypad or just extending the gpio lines to headers? |
| 15:25.23 | prpplague | jbevren: well, i'm tossing around basically about 5 different layouts |
| 15:25.38 | prpplague | jbevren: 1) just providing the cartridge buss |
| 15:25.58 | prpplague | jbevren: 2) providing all the connections to a header |
| 15:25.59 | *** join/#edev redblue (i=star@ppp023.110-253-207.mtl.mt.videotron.ca) |
| 15:26.18 | prpplague | jbevren: 3) providing flash and uart as well as headers |
| 15:26.48 | jbevren | I'd take option 1 with flash, uart, and headers :) |
| 15:26.50 | prpplague | jbevren: jbevren 4) providing all the devices, including speaker, buttons and such plus headers |
| 15:26.53 | jbevren | something I could just plug into a pixter |
| 15:26.55 | jbevren | hehe |
| 15:27.25 | prpplague | jbevren: oh you want to use the card edge? |
| 15:27.34 | jbevren | eyah |
| 15:27.39 | prpplague | ahhhh |
| 15:27.43 | jbevren | access to the arm localbus to add trinkets |
| 15:27.50 | prpplague | none of what i was looking to do was to keep the cardedge |
| 15:27.56 | jbevren | such as IR remote transmitters, extra GPIO chips, etc |
| 15:28.07 | jbevren | maybe even a camera hehe |
| 15:28.10 | prpplague | jbevren: right we want to use the bus, i just wasn't gonna use the cardedge |
| 15:28.19 | jbevren | ohh |
| 15:28.26 | jbevren | so how do we get to the bus? |
| 15:28.41 | prpplague | jbevren: hehe, thats what i'm telling you, hehe |
| 15:28.45 | prpplague | jbevren: picture this |
| 15:28.56 | jbevren | meh :P listening |
| 15:28.59 | prpplague | jbevren: desolder the cardedge and all the external wires |
| 15:29.04 | prpplague | jbevren: that leaves holes |
| 15:29.06 | jbevren | oh |
| 15:29.06 | jbevren | yeah |
| 15:29.13 | prpplague | jbevren: take that board, and drop it ontop of mine |
| 15:29.20 | prpplague | jbevren: solder into place |
| 15:29.41 | jbevren | that would be cool for sure. I was thinking of a more casual hacker that wants to just stick a dev board into his pixter |
| 15:29.47 | prpplague | the only item that woun't connect would be the lcd |
| 15:29.49 | jbevren | I'd take your solution with the removal of cartport etc |
| 15:30.14 | prpplague | jbevren: ahh |
| 15:30.27 | prpplague | jbevren: well the cardedge would make things very expensive |
| 15:30.41 | prpplague | jbevren: it would be cheaper to just product a converter board |
| 15:30.55 | prpplague | jbevren: say convert the bus to a .1" header |
| 15:31.56 | jbevren | expense due to board thickness or? |
| 15:32.02 | prpplague | jbevren: yea |
| 15:32.13 | jbevren | ahh |
| 15:32.15 | prpplague | jbevren: that thickness is major expensive |
| 15:32.16 | jbevren | gotcha |
| 15:32.27 | prpplague | i mean its doable |
| 15:32.46 | prpplague | but really i'd think the object was to make things easy and cheap |
| 15:32.46 | jbevren | nod, I understand now |
| 15:32.50 | jbevren | yeah |
| 15:38.37 | prpplague | jbevren: soooo |
| 15:38.47 | jbevren | so..? :) |
| 15:38.48 | prpplague | jbevren: i'm stuck deciding on how much is tooooooo much |
| 15:38.52 | jbevren | heh |
| 15:38.53 | jbevren | KISS |
| 15:39.03 | jbevren | just do devices that are on cables |
| 15:39.31 | jbevren | you could include a db9 port for an atari/sega-style controller |
| 15:39.37 | prpplague | hehe |
| 15:39.43 | jbevren | that'd work with the gpio lines I think maybe |
| 15:39.43 | jbevren | hehe |
| 15:39.45 | prpplague | jbevren: see, now you are getting the itch |
| 15:39.52 | jbevren | naw |
| 15:39.53 | jbevren | Ive had the itch |
| 15:40.00 | jbevren | you should see what I've thought up for the c64 ages ago |
| 15:40.08 | jbevren | I even went so far as to design a 40bit filesystem |
| 15:40.20 | jbevren | although I never got past the allocation model |
| 15:40.52 | jbevren | :D |
| 15:41.14 | jbevren | but anyway.. if the GPIO lines all use a grounded signal for the joypad and buttons, a sega controller would work nicely |
| 15:41.17 | prpplague | jbevren: ok, one last question |
| 15:41.28 | jbevren | yeah? |
| 15:41.43 | prpplague | jbevren: should i re-use the existing pcb parts in the pixter? or should i just do new parts on the pcb? |
| 15:41.46 | *** part/#edev cbrake (n=cbrake@cpe-65-25-51-117.neo.res.rr.com) |
| 15:42.01 | jbevren | as long as one is desoldering.. |
| 15:42.10 | jbevren | I dont see why I cant just pull my power switch off its board :) |
| 15:42.32 | prpplague | jbevren: hmm, i'd have to do layouts and such for that |
| 15:43.07 | jbevren | did you think of providing drop-in pads for the devices a-la the way youre doing it for the main board? |
| 15:43.40 | prpplague | ahh good point |
| 15:45.43 | jbevren | if you place the respective boards near the pads on the pixter board, that's less trace to route too |
| 15:50.34 | prpplague | jbevren: headphone socket important? |
| 15:50.47 | jbevren | hm |
| 15:50.52 | jbevren | is the audio stereo? |

| 15:51.47 | jbevren | iirc, the TI dac datasheet said stereo, but how it's wired is another question :) |
| 15:51.58 | jbevren | I'd put pads on for a headphone jack |
| 15:52.05 | jbevren | I've used it at least once |
| 15:52.06 | prpplague | i can reuse the power switch, the volume control, the 4-way pad, and the audio section |
| 15:52.17 | prpplague | jbevren: the reset button and the a/b buttons aren't usable |
| 15:52.23 | prpplague | those are junk |
| 15:52.27 | jbevren | ah |
| 15:52.35 | jbevren | you can add buttons to the board for those though |
| 15:53.13 | prpplague | yea |
| 15:53.57 | prpplague | ok so there would be no need to desolder the power switch connection, the 4-way pad or the audio |
| 15:54.51 | prpplague | ok i think i have a plan working up |
| 15:57.24 | jbevren | so about using the microchip ethernet controller |
| 15:57.42 | jbevren | does the pixter have a SPI bus exposed? |
| 15:57.55 | prpplague | jbevren: i was planning to just use a header for you to solder the olimex or EDTP boards |

| 17:27.26 | jbevren | hehe |
| 17:28.15 | prpplague | jbevren: hehe, suppose to use my nick, so i know you responded, hehe |
| 17:28.38 | prpplague | jbevren: i'm drawing a blank on the size of the resistors you used for the jtage debug mode? |
| 17:28.45 | prpplague | jbevren: was it 47k or 470k ? |
| 17:28.59 | jbevren | prpplague: pong :) |
| 17:29.02 | jbevren | one was 47k |
| 17:29.06 | jbevren | the other was 47 ohms |
| 17:29.20 | prpplague | jbevren: hehe |
| 17:29.22 | jbevren | they were just arbitrarily grabbed |
| 17:29.30 | prpplague | jbevren: hmm ok |
| 17:29.30 | jbevren | two 47 ohm ones would probably work |
| 17:30.19 | jbevren | or te 51 ohm resistors people commonly use to terminate jtag adapters :0 |
| 17:30.20 | jbevren | <PROTECTED> |
| 17:32.04 | jbevren | prpplague: offtopic, what do you think of gumstix, other than their stupid high-density connectors? |
| 17:32.46 | prpplague | yea its a good idea, but i just don't like their whole attitude and OSS support |
| 17:38.02 | prpplague | jbevren: ok it looks like they are using two 33k ohm resistors to pull it high |
| 17:38.21 | prpplague | should be able to remove c8 and connect a wire to ground |
| 17:45.19 | jbevren | hm |
| 17:45.21 | jbevren | dunno |
| 17:45.31 | jbevren | you cant hard-ground the lines in the pixter's config |
| 17:45.43 | jbevren | unless its not supposed to bootstrap after reset with debug on :) |
| 17:48.09 | prpplague | jbevren: right, thats why i said you could use the 33k ohm resistors |
| 17:48.33 | jbevren | ah ok |
| 17:48.39 | jbevren | I understand now |
| 17:48.47 | jbevren | dont mind my missing your comments, I'm working too atm of course :) |
| 17:52.33 | prpplague | hehe, np |
| 17:53.16 | prpplague | i'm pretty sure all you need to do is cut that one trace and solder a wire to Vss |
| 17:55.12 | prpplague | you said your system wouldn't boot if you hard wired it to ground? |
| 17:55.33 | prpplague | that sounds correct |
| 17:55.52 | prpplague | you'd get close to a dead short between Vss and Vcc |
| 18:01.13 | prpplague | jbevren: weird |
| 18:01.24 | prpplague | jbevren: the lh79520 test pins are totally different |

| 18:09.16 | jbevren | neat board |
| 18:09.17 | jbevren | heh |
| 18:09.52 | chouimat|ibook | prpplague: this one will look more interesting (for me) http://www.olimex.com/dev/cs-e9315.html |
| 18:10.21 | prpplague | chouimat|ibook: you know there is a ep93xx channel right? |
| 18:10.49 | chouimat|ibook | prpplague: yup :) |
| 18:12.20 | prpplague | ah ha |
| 18:12.32 | prpplague | jbevren: the user manual is WRONG |
| 18:12.35 | prpplague | jbevren: there is an errata |
| 18:12.40 | jbevren | doh! |
| 18:12.42 | jbevren | what's correct? |
| 18:12.43 | prpplague | jbevren: it is the same as the lh79520 |
| 18:13.18 | prpplague | jbevren: test2 needs to be pulled high and the test1 pulled low for jtag debug |
| 18:17.48 | jbevren | that explains whyI cant pull them together |
| 18:18.24 | jbevren | hehe |
| 18:18.29 | jbevren | I'm grounding both via resistors lol |
| 18:18.39 | jbevren | one must be weak enough to leave test2 high |
| 18:18.40 | jbevren | :D |
| 18:18.53 | prpplague | jbevren: right probably the one that is 47k |
| 18:19.06 | prpplague | jbevren: which is less than the 33k on the Vcc side |
| 18:19.31 | prpplague | jbevren: sorry the 33k on the Vcc side is less |
| 18:19.57 | prpplague | jbevren: you should be able to run it with just the test1 pulled low |
| 18:20.10 | prpplague | jbevren: think you'd have time to check that? |
| 18:20.47 | jbevren | perhaps during lunch (1.5 hours) |
| 18:22.03 | prpplague | jbevren: ok, thanks |
| 18:22.14 | jbevren | remind me at 3pm cst (its 1:22 now) hehe |
| 18:22.23 | jbevren | or better, shortly before :) |
| 18:22.30 | prpplague | jbevren: i'm in the process of soldering my board so it will be a little while before i get my jtag back up |
| 18:23.07 | jbevren | nod |
| 18:23.08 | jbevren | brb |
| 18:23.43 | prpplague | jbevren: i did a surface mounter rs-232 level shifter earlier |
| 18:28.21 | prpplague | jbevren: i knew that lh79524/25 should be close to the same as the lh79520. |
| 18:28.36 | prpplague | jbevren: thats why i was surprised on the difference in the documents |
| 18:35.23 | jbevren | nod |
| 18:35.47 | prpplague | jbevren: ho ho hum |
| 19:33.27 | prpplague | jbevren: dev board is coming along nicely |
| 19:35.40 | jbevren | cool |
| 19:36.12 | prpplague | got power, jtag, reset and audio mounter |
| 19:36.18 | prpplague | mounted and working |
| 19:37.10 | jbevren | hm I like this cs-e9301 board |
| 19:37.17 | jbevren | (the olimex.com one linked earlier) |
| 19:37.58 | prpplague | doh, mounted the power switch in the wrong place |
| 19:40.52 | jbevren | olimex doesnt sell to end users or do they? |
| 19:47.27 | prpplague | jbevren: hey its about lunch time hehe |

| 20:10.53 | prpplague | jbevren: ok, so you don't have anything conencted, but you didn't remove anything off the board? |
| 20:10.58 | jbevren | can you look up the regsiter for the framebuffer address for me real quick? |
| 20:11.04 | jbevren | I'll attempt writing to the fb to be sure |
| 20:11.06 | jbevren | right. |
| 20:11.07 | prpplague | yea on sec |
| 20:11.18 | jbevren | same setup as I had before, but I didnt hook test1 to the 47k |
| 20:11.46 | prpplague | jbevren: which fb address do you want? |
| 20:12.05 | jbevren | the regsiter for the cldc |
| 20:12.07 | jbevren | um |

| 20:13.58 | jbevren | debug :) |
| 20:14.04 | prpplague | loverly |
| 20:14.28 | prpplague | hmm should i provide a jumper to enable/disable debug? |
| 20:14.32 | prpplague | or leave it all in debug |
| 20:14.35 | jbevren | hm |
| 20:14.39 | jbevren | it operates normally in debug |
| 20:14.46 | jbevren | you should provide a jumper for CS1 though |
| 20:15.06 | jbevren | since debug mode doesnt really change much, I"d just leave it jumped for dbg |
| 20:15.14 | prpplague | ok |
| 20:15.27 | jbevren | if you like, you can just extend dbg from the board to a ground pin on the board |
| 20:15.35 | jbevren | a developer can lift the dbg line off the pin if he chooses :) |
| 20:15.57 | prpplague | jbevren: oh are you using a resistor, or hard wired to ground? |
| 20:16.07 | jbevren | resistor, 47k |
| 20:16.13 | jbevren | I dont like hard-wiring logic inpjuts |
| 20:16.25 | prpplague | jbevren: ok, so you are using a 47k on test2? |
| 20:16.28 | prpplague | to ground? |
| 20:16.33 | jbevren | yeah |
| 20:16.54 | jbevren | hm |
| 20:16.55 | prpplague | i would think you are using just the 47 ohm resistor |
| 20:16.57 | jbevren | test1 is grounded |
| 20:17.33 | jbevren | test1 -> 47ohm -> gnd |
| 20:17.46 | prpplague | yea, thats right |
| 20:17.50 | prpplague | ok good |
| 20:17.57 | jbevren | k |
| 20:17.59 | jbevren | bbl :) |
| 20:18.00 | prpplague | that makes more sense |
| 20:19.01 | prpplague | my lh79520 reference design just shows test1 being hardwired to ground |
| 20:19.38 | prpplague | of course it doesn't have that 33k ohm resistor pullup either |
| 20:20.03 | prpplague | if i cut that trace, and wire the end of the 33k to ground that should be ok |
| 20:20.35 | prpplague | yea thats the ticket |
| 20:21.49 | prpplague | jbevren: ha just got an email from my sharp contact |
| 20:22.13 | prpplague | jbevren: confirms that the pullups are to turn debugging off, just pull test1 low for debugging |

| 20:29.40 | MonMotha | oh, hum |
| 20:29.51 | MonMotha | 4mb or 4MB? |
| 20:30.03 | prpplague | MonMotha: yea i thought about the webpal board, but its 5v iirc |
| 20:30.10 | MonMotha | the stuff in the DCT5000 will run at 3.3 if you've got one |
| 20:30.11 | prpplague | MonMotha: megabyte |
| 20:30.20 | MonMotha | and there's quite a bit in there |
| 20:30.39 | prpplague | MonMotha: yea, sorry most of my stuff is still in storage in the states |
| 20:31.16 | prpplague | MonMotha: i found a bunch of items with the TE28F320 from intel, but they are very expensive |
