Aug 31 02:00:11 unfortunately the pins used by the JTAG engine go to the PIC Aug 31 02:01:03 bummer Aug 31 02:01:59 so the cheaper one is better eh? Aug 31 02:02:10 definitively Aug 31 02:02:28 it has all ports freely available Aug 31 02:02:48 so a carrier board would be helpful? Aug 31 02:02:59 yes Aug 31 02:03:17 The module alone is not usable Aug 31 02:04:16 sure it is. You can put it on your monitor and look at it. or wear it as jewlery.... :-) Aug 31 02:04:30 Its not quite heavy enough to be a paperweight. Aug 31 02:04:49 heh Aug 31 02:05:15 but the code that is developed can work for both. Aug 31 02:05:27 (minus the bits that talk to the micro) Aug 31 02:06:34 ep1220: do you have the PCB EDA package? Aug 31 02:06:55 All 4 bits of the JTAG engine go to the PIC. Aug 31 02:07:16 bummer Aug 31 02:07:33 I do have an older CADSTAR, plus have access to PADS and Altium Designer. Aug 31 02:07:56 if you have X on a linux box you can download it... Aug 31 02:08:06 most distro's have it Aug 31 02:08:58 Some month's ago I installed the PCB/EDA on a SUSE, but just looked at the JTAG sample Aug 31 02:09:09 BTW: Do you know http://www.lis.inpg.fr/realise_au_lis/kicad/ ? Aug 31 02:11:32 no...but it looks interesting. Aug 31 02:11:48 I found it a few days ago, did not try yet. Aug 31 02:11:55 I'll download and play Aug 31 02:12:17 the PCB software works fine for most of the apps that I do. Aug 31 02:14:01 I can also send pdf's Aug 31 02:14:11 but its better to view in the native app. Aug 31 02:14:50 I think I should be able to view he native files Aug 31 02:15:17 I have no hope for using the FTDI JTAG-engine on the 2232PB Aug 31 02:15:47 2 of the pins are even shorted together. According to http://www.dlpdesign.com/usb/dlp-2232pbv14.pdf Aug 31 02:17:34 One could only use the GPIOs AC0-3 for bitbanging Aug 31 02:17:40 But that would be slow Aug 31 02:18:04 very..the engine is what we want. Aug 31 02:21:40 I'll look and see what I have to mod on my layout to accomodate the other unit Aug 31 02:21:53 ar you using the M or ? Aug 31 02:22:00 * ka6sox-away can't remember. Aug 31 02:23:56 DLP2232M Aug 31 02:26:35 I looked at that one for my purposes and decided to go with the micro for some "local" smarts. Aug 31 02:27:51 You could implement a JTAG engine on the Micro. Aug 31 02:28:33 yep. Aug 31 02:29:31 I hardly no PIC. Aug 31 02:30:14 s/no/know/ Aug 31 02:30:50 I tried 8051, effective instruction rate 12MIPS Aug 31 02:31:08 thats a fast 8051 Aug 31 02:31:20 most of them are like 3MIPS Aug 31 02:31:28 depending on instruction set mix Aug 31 02:31:47 I know. It is the Cypress USB2 chip used by the digilent Spartan USB IF Aug 31 02:32:04 thats nice but pricey Aug 31 02:32:13 48MhZ clock, 4 cales/instruction (believe a Dallas 8051) Aug 31 02:32:32 dallas' implementation is good. Aug 31 02:32:44 still an old core Aug 31 02:33:13 With this chip i got 0,5 to 0,8MHZ equivalent JTAG clock Aug 31 02:33:30 the FTDI does 6MHz Aug 31 02:33:34 the PIC only has 35 instrucions. Aug 31 02:34:04 all single clock cycle ? Aug 31 02:34:10 yes Aug 31 02:34:23 and I think it runs at 20mhz Aug 31 02:34:36 I see a 20MHz crystal on 2232PB schematic Aug 31 02:34:58 I don't think its a 2 phase clock Aug 31 02:35:13 how much RAM ? Aug 31 02:38:10 368 Aug 31 02:39:43 not a big buffer Aug 31 02:40:01 yep Aug 31 02:40:41 well...I need to get some sleep here...be on in about 8hrs. Aug 31 02:40:49 thanks for looking at that. Aug 31 02:41:02 Time for lunch here :-) Aug 31 02:42:10 enjoy! **** ENDING LOGGING AT Wed Aug 31 02:59:56 2005
