| 15:59.03 | dwf_starband2 | the guys at #microcontrollers said you guys might know the answer to my question |
| 16:00.10 | dwf_starband2 | i have an asix presto usb programmer that I want to use with my pvk40 board, i got them a year ago but didnt really do much with them, and have switched to linux since then, where do i look to find out about using the programmer in linux? |
| 16:02.20 | dwf_starband2 | prpplagueyea it's ft2232 based |
| 16:02.21 | dwf_starband2 | 07:01prpplague--enable-presto_ftd2xx Enable building support for ASIX Presto Programmer |
| 16:02.21 | dwf_starband2 | prpplagueusing the FTD2XX driver |
| 16:02.45 | prpplague | dwf_starband2: its fully supported under openocd |
| 16:03.02 | prpplague | dwery: which means all the specs for the board be be determined from the source code |
| 16:03.14 | prpplague | dwf_starband2: oops that was for you |
| 16:03.43 | dwf_starband2 | so what does that mean i need to do? |
| 16:03.59 | dwf_starband2 | im sorry, but im learning, so that doesnt mean a lot to me |
| 16:04.06 | prpplague | dwf_starband2: depends on what you want to do |
| 16:05.25 | dwf_starband2 | i want to be able to 1. send programs to the chip, 2. start learning how to write the programs and compile them and send them to the chip |
| 16:05.33 | *** join/#openjtag jkilb_ (n=jkilb@p5B2085C0.dip0.t-ipconnect.de) |
| 16:05.42 | dwf_starband2 | im learning, and that should be the first step to learning shouldnt it? |
| 16:07.21 | dwf_starband2 | does openocd work like the up program that came with the programmer? |
| 16:07.42 | prpplague | dwf_starband2: 1) which chip , 2) which interface? |
| 16:08.17 | prpplague | dwf_starband2: openocd is intended to work with the jtag interface of ARM based devices |
| 16:08.29 | dwf_starband2 | pic16f877a |
| 16:09.05 | dwf_starband2 | what do you mean by interface, how it would be connected to the computer for the transfer? that is through usb |
| 16:09.26 | prpplague | dwf_starband2: there many different interfaces to "program" a device |
| 16:09.50 | prpplague | dwf_starband2: jtag, isp, bitbang, spi, i2c, and a ton of propriety interfaces |
| 16:10.40 | dwf_starband2 | ok, how would I know what i have? |
| 16:11.12 | prpplague | dwf_starband2: check the datasheet on your pic, it should tell you which interfaces it support |
| 16:11.24 | dwf_starband2 | ok |
| 16:11.49 | prpplague | dwf_starband2: i suspect it probably uses an isp interface |
| 16:13.09 | prpplague | dwf_starband2: http://www.linuxjournal.com/article/3045 |
| 16:13.16 | prpplague | dwf_starband2: might give that a quick read |
| 16:13.36 | dwf_starband2 | ok |
| 16:13.59 | prpplague | dwf_starband2: you can take that pic prg app and modify it for the presto pretty easy |
| 16:14.35 | prpplague | dwf_starband2: yet another howto - http://linuxgazette.net/issue79/sebastian.html |
| 16:23.22 | prpplague | drath: ping |
| 16:26.27 | prpplague | dwf_starband2: http://forum.sparkfun.com/viewtopic.php?t=2908&highlight=presto |
| 16:30.16 | dwf_starband2 | i didnt see any reference to linux on that page |
| 16:32.23 | prpplague | dwf_starband2: no, it was just a discussion of the features |
| 16:33.14 | prpplague | dwf_starband2: pp doesn't seem to support libft2232 based devices from what i can tell |
| 16:41.15 | dwf_starband2 | http://vasco.gforge.enseeiht.fr/index.php?article=Odyssey.html |
| 16:41.21 | dwf_starband2 | does that look prommising? |
| 16:42.52 | prpplague | dwf_starband2: i haven't done pic in years, so i'm not sure how much i can help you on a new product |
| 16:43.17 | dwf_starband2 | no worries, you have helped alot with getting me started looking in the right direction |
| 16:43.19 | dwf_starband2 | thanks |
| 16:44.25 | prpplague | dwf_starband2: yea that is a parallel port based programmer |
| 16:44.38 | prpplague | dwf_starband2: from the looks of the code it could be modified to support the ft2232 |
| 17:17.08 | drath | prpplague: pong |
| 17:17.29 | drath | prpplague: just got home from the office, gotta grab something to eat |
| 17:17.34 | drath | prpplague: i'll be back in ~15 minutes |
| 17:17.44 | prpplague | drath: np, i think i've forgotten what i was going to ask |
