May 10 00:01:21 <ka6sox> sometimes they are good and sometimes they suck.
May 10 00:33:17 <beewoolie> Yeah.  Me too.
May 10 00:33:20 <beewoolie> nite
May 10 11:31:10 <ep1220> [g2] Some time ago we talked about the Digilent USB/JTAG cable.
May 10 11:31:16 <ep1220> [g2]  Did You get information on it ?
May 10 11:36:41 <[g2]> ep1220, A while ago I had some info
May 10 11:37:02 <[g2]> I've been playing with the parallel cable today significant joy
May 10 11:38:15 <ep1220> [g2]. I am still interested in the USB one.
May 10 11:38:41 <ep1220> Do You know which pins of the 68013 the JTAG header connects to ?
May 10 11:39:11 <[g2]> not offhand, but iirc the schematic is on the digilentinc web site
May 10 11:39:47 <[g2]> the problem is the usb device driver on the 68013 is custom and there's only a windows driver for it
May 10 11:39:55 <[g2]> and it's not open source
May 10 11:41:27 <ep1220> [g2] I know a bit about the chip. So i could write custom firmware.
May 10 11:41:49 <ep1220> i go check out the digilent site once more.
May 10 11:44:20 <[g2]> ep1220, my understanding is you'd have to cut the traces to the eeprom that has the program in it that runs
May 10 11:44:45 <[g2]> clearly, somebody who know a little about the chip would be very helpful
May 10 11:45:24 <[g2]> I'd also take a look at the usb2 board which has the 68013 on it also and is downloaded with firmware from what I can tell
May 10 11:46:07 <ep1220> The EEPROM can have a program; or just a USB ID
May 10 11:46:16 <ep1220> and firmware is downlaoded from the PC
May 10 11:46:46 <ep1220> In 2nd case it would be relative easy to replace it
May 10 11:47:02 <[g2]> nod. I think that's the way the USB2 card is setup
May 10 11:47:24 <[g2]> do you have the dev kit or are you able to programmer them ?
May 10 11:47:32 <[g2]> programmer heh
May 10 11:47:34 <[g2]> program
May 10 11:48:51 <ep1220> I do have the devkit.
May 10 11:49:06 <[g2]> excellent
May 10 11:49:28 <ep1220> the digilent documentation page has a link supposed to show a schematic.
May 10 11:49:37 <ep1220> but there is no schematic in it.
May 10 11:50:58 <ep1220> Do you have such a USB cable?
May 10 11:51:09 <[g2]> http://www.digilentinc.com/products/Documentation.cfm
May 10 11:51:19 <[g2]> that has the schematic for the usb2 card
May 10 11:51:39 <[g2]> and a pdf for the cable
May 10 11:51:52 <ep1220> I know this one, but does it help for the cable?
May 10 11:52:10 <ep1220> They claim the cable can handle voltage down to 1.5V
May 10 11:54:12 <ep1220> So there might be a level shifter in there.
May 10 11:57:18 <ep1220> the pdf schematic for the cable, on my PC shows the same page as the reference manual
May 10 11:58:02 <ep1220> well, not exactly, but no schematic in there
May 10 12:16:16 <ep1220> [g2] 1st I will check the drivers in the Adept Suite
May 10 12:16:40 <ep1220> to see if i can find out if firmware is downloaded
May 10 12:16:46 <[g2]> ok
May 10 12:17:00 <[g2]> are you programmed the 68013 much ?
May 10 12:17:10 <ep1220> I will be back tomorrow (already late here ..)
May 10 12:17:17 <[g2]> ok
