Aug 14 12:47:57 hey prpplague Aug 14 12:48:27 vmaster: hey Aug 14 12:48:48 vmaster: we are getting ready to do a run of some ft2232 based jtag devices Aug 14 12:49:02 vmaster: similiar to the schematic you shared with me awhile back Aug 14 12:49:49 mhh, which one exactly? i've seen too many lately Aug 14 12:50:02 vmaster: hehe Aug 14 12:50:13 vmaster: you email me a design about 6 months ago Aug 14 12:51:20 vmaster: iirc you said your professor had done the design Aug 14 12:51:38 mhh Aug 14 12:51:42 yeah, i remember Aug 14 12:51:59 the one using opto-couplers? Aug 14 12:52:25 vmaster: yea Aug 14 12:52:28 it's not really an ideal solution - the parts are expensive, and only support 3.3v and 5v, but not less than that Aug 14 12:52:45 i have a newer design that supports a wider range of voltage, using cheaper parts Aug 14 12:53:03 vmaster: yea, the boss has re-done the design Aug 14 12:53:23 vmaster: one thing he was asking about was the system reset is active high Aug 14 12:53:43 vmaster: whats the reasoning behind that since most of the systems use reset active low? Aug 14 12:53:57 i guess there was no reasoning at all Aug 14 12:54:40 ahh ok Aug 14 12:55:00 vmaster: would like for me to get permission for you to see the schematic? Aug 14 12:56:23 i'm wondering if the olimex jtag dongle uses reset active high as well Aug 14 12:56:38 i don't think, so, but i'm still waiting for one to arrive Aug 14 12:57:02 i've pmed you a link to a newer design Aug 14 12:57:17 not sure if it's ok to make that one public, so i'd rather not have it on purl's log :) Aug 14 12:58:08 ahh ok Aug 14 20:30:38 vmaster: ping Aug 14 20:33:56 prpplague: pong Aug 14 20:34:07 you're lucky, just got home from a soccer match Aug 14 20:34:20 hehe Aug 14 20:34:30 i'm forwarding you one more schematic Aug 14 20:34:36 vmaster: if you get time have a look Aug 14 20:34:40 yeah, sure Aug 14 20:36:16 otw Aug 14 20:36:28 brb Aug 14 20:39:57 poof **** ENDING LOGGING AT Tue Aug 15 02:59:58 2006
