| 00:39.46 | roxfan | ping timeout! |
| 00:41.32 | prpplague | solar update time |
| 00:41.43 | prpplague | solar ok, lets start with azulie |
| 00:42.14 | prpplague | solar i've finished a rough schematic done, and i've gone over the rough layout with my layout guy |
| 00:42.21 | prpplague | solar he's starting on it this weekend |
| 00:42.32 | prpplague | solar so we should have something monday or tuesday to look at |
| 00:42.56 | prpplague | solar i've got one of the M5930 boards that i've hooked up to a ft2232 board |
| 00:43.07 | prpplague | solar going to test tomorrow using avrdude to flash the boards |
| 00:43.17 | prpplague | solar and test the uart interface to the atmega127 |
| 00:43.18 | prpplague | 128 |
| 00:43.35 | prpplague | solar i don't expect any problems, but i'll doc it on the flyswatter page |
| 00:44.17 | prpplague | solar i can purchase the parts we need from AML at their bulk qty price |
| 00:44.36 | *** join/#edev zachb (n=zachb@c-71-233-105-197.hsd1.ma.comcast.net) |
| 00:44.40 | prpplague | solar i'm talking to the pactec rep about the case to see if we can get different colors |
| 00:45.25 | prpplague | solar as far as the M8050 project, i've spent the week working on the board with our retired EE, he came in at the request of the owners |
| 00:45.56 | prpplague | solar we found about 20+ critical problems with the design, we've got some pieces/parts ordered to white-wire to boards |
| 00:46.10 | prpplague | solar as should be tuesday for us to ship to you |
| 00:46.37 | prpplague | solar i have time scheduled for monday to get all the user space stuff you need as well the specs for what we need |
| 00:47.03 | prpplague | solar i spent alot of time this week in WTF meetings trying to save the project, so i think we are good to go |
| 00:47.04 | zachb | I have this IC w/ internal vregs, and it has a bunch of vdd's scattered around the chip. These *don't* need to be connected, correct? They're just there for convenience...right? |
| 00:47.37 | prpplague | zachb generally they need to be connected for several reasons |
| 00:47.37 | g1powermac | zachb, I doubt it |
| 00:47.56 | g1powermac | they should be connected |
| 00:48.09 | prpplague | zachb usually it is to keep the current on any given pin low, as well as keeping EMI/EMF/ESD issues to a min |
| 00:48.24 | prpplague | zachb if it is marked as a Vcc, you need to connect it |
| 00:48.44 | zachb | Nono, they're like AVDD's & IOVDD's |
| 00:49.01 | g1powermac | heya prpplague |
| 00:49.03 | zachb | the chip only *takes in* a Vcc on one pin |
| 00:49.30 | prpplague | zachb AVdd indicates the power used for the analog devices inside the device |
| 00:49.37 | zachb | Yes, I know |
| 00:49.54 | zachb | But it has about 4 pins labeled AVdd... it has internal regulators, though |
| 00:50.28 | prpplague | zachb regulators or not, generally you want all four pins connected |
| 00:50.42 | prpplague | zachb there is a _reason_ they have four pins |
| 00:50.51 | prpplague | zachb they might not tell you, but there is one |
| 00:51.03 | zachb | Yeah... it just seemed really odd to have them spread all over the chip like that... |
| 00:51.13 | solar | prpplague: ok. That really does not slow me down all that much. I've got a few cross compile things to tackle w/ a bit of the gui software |
| 00:51.15 | prpplague | zachb it might be simply the fact that the circuit needs to have available 100mA, but each pin can only carry 25mA |
| 00:51.52 | zachb | prpplague: ah, that makes sense |
| 00:51.58 | prpplague | solar i'm really exited about the azulie board, the ft2232 stuff doesn't appear to have been done much with the arduino stuff |
| 00:52.14 | zachb | Thanks a ton |
| 00:52.16 | prpplague | solar you'll be able to make an adapter for the flyswatter to program the atemga stuff when i'm done |
| 00:52.18 | prpplague | zachb np |
| 00:52.44 | zachb | you saved me a PCB rev ;P |
| 00:53.39 | roxfan | i wonder if there's some code around to debug pics via an ft2232 |
| 00:54.15 | prpplague | roxfan hmm is there a linux app for doing that via a parport device? |
| 00:54.27 | roxfan | not sure |
| 00:54.35 | solar | prpplague: I'd assumed it would be a 6 pin female ISP header |
| 00:55.05 | *** join/#edev i_am_numbers (n=novatheo@host47.newschoolips.n.subnet.rcn.com) |
| 00:55.31 | prpplague | solar most of the avr stuff is a 2x5 header |
| 00:55.35 | roxfan | here's something http://www.google.com/codesearch?q=show:_ryax882qLk:Kvj4XNJrdis:hl0FlwBQRvg |
| 00:55.40 | prpplague | solar but i can match whatever is out ther |
| 00:57.06 | roxfan | i guess should be doable with some bit banging... |
| 00:57.12 | solar | You like the case? I got one shipped to me. I have mixed feelings |
| 00:57.19 | prpplague | solar oh? |
| 00:57.34 | prpplague | solar better tell me now then |
| 00:57.47 | prpplague | solar what parts don't you like? |
| 00:58.13 | prpplague | hmm, yea the arduino stuff is using a 2x3 header |
| 00:58.22 | solar | does it feel sturdy enough to you? |
| 00:58.51 | prpplague | yea its pretty sturdy when it is screwed together |
| 01:01.06 | prpplague | solar http://www.sparkfun.com/commerce/product_info.php?products_id=8508 |
| 01:01.09 | prpplague | solar can use that |
| 01:02.22 | solar | yeah |
| 01:03.07 | prpplague | hmm, would have to use that with female headers since i don't recal ever seeing a 2x3 idc header |
| 01:04.00 | MonMotha | prpplague: I presume you mean a male header, since I know there are female 2x3 IDC |
| 01:04.56 | prpplague | MonMotha 2x3 idc female connector for ribon cable? |
| 01:05.25 | prpplague | MothaWork 2x3 is pretty non-standard |
| 01:11.24 | MonMotha | prpplague: well, I've got a bunch |
| 01:11.34 | MonMotha | bought them at a local place in Indianapolis |
| 01:11.41 | MonMotha | I'm sure he'd happily sell you a bunch if you can't find them elsewhere |
| 01:11.42 | prpplague | MonMotha interesting |
| 01:11.44 | prpplague | looks |
| 01:11.53 | MonMotha | I bought them to use for AVR ISP |
| 01:13.01 | MonMotha | I will admit that I don't see them often, but they are out there |
| 01:13.07 | MonMotha | I know you can get various discrete wire solutions |
| 01:13.17 | MonMotha | FCI has a good series |
| 01:13.27 | MonMotha | Molex SL might also have 2x3 options |
| 01:14.14 | prpplague | yea just found the fci, very pricy |
| 01:14.43 | prpplague | hmm |
| 01:14.57 | prpplague | $1 from sparkfun is pretty cheap |
| 01:15.02 | prpplague | for those adapters |
| 01:15.13 | prpplague | problem is i have to make an adapter for the flyswatter |
| 01:15.25 | MonMotha | hum, you know, the JTAGICE mkII comes with a 2x3 IDC header |
| 01:15.32 | MonMotha | so they're most certainly out there |
| 01:15.40 | MonMotha | it comes on the JTAG to ISP adapter thingie |
| 01:16.03 | prpplague | MonMotha yea i know they were but i figured they were pretty non-standard |
| 01:16.53 | prpplague | hmm |
| 01:17.23 | prpplague | so we need a 2x7 arm jtag to either a 2x5 isp or 2x3 isp |
| 01:17.33 | prpplague | alot with both a 2x5 cable and a 2x3 cable |
| 01:17.54 | *** part/#edev i_am_numbers (n=novatheo@host47.newschoolips.n.subnet.rcn.com) |
| 01:19.02 | prpplague | $2 for the board, $2 for the 2x5 cable and $2 for the 2x3 cable, so $6 * 3, $18 for resale |
| 01:20.11 | solar | alot of ppl just seem to take existing arduinos and make them to the programmer |
| 01:21.51 | MonMotha | 2x5 is reasonably standar |
| 01:21.51 | MonMotha | d |
| 01:22.35 | prpplague | solar yea, the primary reason i am looking at this is the azule will have basically the flyswatter onboard for the uart and isp programming |
| 01:24.02 | prpplague | solar what do you use to program you arduino boards? |
| 01:33.30 | solar | prpplague: the USB port |
| 01:34.01 | solar | however. Thats not the bootloader. Which comes pre-programed afaik |
| 01:38.54 | Madsy | Uh.. is "prerequisity" spelled correctly? :-) |
| 01:44.23 | prpplague | solar ahh so you never program the via the ISP for the bootloader? |

| 01:52.50 | solar | prpplague: I have not. But I'd like to ship with a ardy-aware-128 one loaded |
| 02:14.54 | prpplague | solar thats no problem |
| 02:15.28 | prpplague | solar the ft2232 can flash the avr directyl |
| 02:15.48 | prpplague | solar so they can use the uart to flash the device via the arduino bootloader, or via the standard isp |
| 02:16.11 | solar | prpplague: did you try the Morse.pde on the arduino that went along with the fun packing? |
| 02:16.42 | prpplague | solar sorry no, haven't had time yet |
| 02:16.56 | prpplague | solar the azulie and the 8050 stuff have been top priority |

| 02:28.51 | solar | the ft232R can do the same thing right? |
| 02:39.55 | prpplague | solar no, the ft232r can only do the uart stuff |
| 02:40.02 | prpplague | solar it can't do the isp programming |
| 02:40.24 | prpplague | solar if you hose the bootloader on on the arduino , you'll need an isp programmer to fix it |
| 02:40.40 | solar | oh yep that would be true |
| 02:42.04 | prpplague | solar with the azulie you can either treat it as an arduino type device using the bootloader, or you can flash it as a standard avr |
| 02:42.10 | prpplague | solar over the same usb connection |
| 02:42.43 | solar | thats handy |
| 02:44.12 | prpplague | yep |
| 02:44.28 | prpplague | its shaping up pretty good |
| 02:44.53 | solar | any pics or pdfs worth seeing? |
| 02:48.29 | prpplague | solar i have the schematics done at the office, nothing at home for you too see at the momment, i should have the layout gerbers by tuesday assuming my layout guy doesn;t run into any problems over the weekend |
| 03:35.32 | Madsy | Anyone have the time to proof-read an introduction I've written to the ARM architecture? |
