| 02:36.26 | dyoung-web | the 2232 should be whackable in short order. i drew a q/d schmatic in PCB with the 2232 and 9536 and hit it with autoroute. its pretty straight forward. |
| 02:41.38 | ka6sox-office | heh |
| 02:41.56 | dyoung-web | not pcb, I used the other one. what was it called again... |
| 02:42.03 | ka6sox-office | eagle |
| 02:42.06 | dyoung-web | yeah that one. |
| 02:42.59 | ka6sox-office | shipping tommorrow morning to me. |
| 02:44.36 | ka6sox-office | how goes the proggie? |
| 02:45.30 | dyoung-web | its not. |
| 02:45.38 | ka6sox-office | ow. |
| 02:45.55 | dyoung-web | I need to mod that board first. |
| 02:46.21 | ka6sox-office | the other one too unstable? |
| 02:46.46 | dyoung-web | no, theres too much crap on it. I cant get to aux-serial. |
| 02:48.29 | ka6sox-office | okay |
| 03:00.55 | beewoolie | Go dyoung. |
| 03:01.23 | beewoolie | Can you tell me what the 9536 is? |
| 03:01.26 | dyoung-web | I didnt say it was GOOD. I basically slapped it down to see how bad it was gonna be. |
| 03:02.02 | beewoolie | Really, how many parts do we need? A crystal, one or two chips (I don't know the 9536 number), and some caps and resistors. |
| 03:02.23 | dyoung-web | The xilinx 9536 is a cpld. that lets us have a wide range of voltage compatibility. |
| 03:02.44 | beewoolie | I should be done in a week or so with this milestone. At that point, I'm going to take a closer look at all of this JTAG stuff. |
| 03:02.58 | beewoolie | dyoung-web: Excellent. I didn't remember the part number. |
| 03:03.30 | beewoolie | What makes you think there is anything else to worry about? I suppose we need to rationalize the interface headers, but the rest should be handle-able in the FPGA/sw dev phase. |
| 03:03.37 | dyoung-web | theres really not a whole lot to it. |
| 03:03.47 | dyoung-web | Nothing else to really worry about. |
| 03:04.12 | dyoung-web | Was I worried? I dont remmeber. |
| 03:04.23 | beewoolie | dyoung-web: Sorry about this. I need to jet. If we get a schematic, I can run it by a EE I know who said he'd vet it for me/us. |
| 03:04.31 | beewoolie | He makes a lot of boards. |
| 03:04.51 | beewoolie | And I'm serious... |
| 03:04.52 | beewoolie | ttfn |
| 03:04.55 | dyoung-web | Cool |
| 03:29.30 | ka6sox-office | what is beewoolie trying to get done and what is the CPLD for? |
| 03:29.40 | dyoung-web | the JTAG Dongle |
| 03:30.18 | dyoung-web | the CPLD is for voltage compatibility. |
| 03:30.21 | ka6sox-office | oh...somebody has been keeping me kinda busy so I haven't gotten to that...but I do Have a Schemmatic. |
| 03:30.23 | dyoung-web | and glue logic. |
| 03:33.41 | dyoung-web | is "splitting" a signal in vhdl as easy as it looks? |
| 03:33.59 | dyoung-web | foo <= bar; baz <= bar; |
| 03:34.00 | dyoung-web | ? |
| 03:34.04 | ka6sox-office | yes |
| 03:34.06 | ka6sox-office | correcto |
| 03:34.47 | dyoung-web | I dont have a HC125 handy; but I do have some SOIC 244's. |
| 03:34.51 | dyoung-web | HC244's |
| 03:35.20 | ka6sox-office | okay...I ordered a bunch of HCT125's |
| 03:35.36 | dyoung-web | I was gonna mod it today though. |
| 03:35.40 | dyoung-web | so I can work on it tommrow. |
| 03:36.03 | ka6sox-office | use the '244...it'll work. |
| 03:36.19 | dyoung-web | is there a major danger in not terminating the extra outputs? |
| 03:36.30 | ka6sox-office | I used 47k pullups to reduce the drain... |
| 03:36.49 | ka6sox-office | in HC parts it is always good to ground unused parts. |
| 03:37.11 | dyoung-web | is 47k too much? |
| 03:37.15 | ka6sox-office | no |
| 03:37.16 | dyoung-web | the Xilinx AN says 500-1000 ohm. |
| 03:37.45 | ka6sox-office | 1k ohm means you draw 5ma when its pulled down. |
| 03:38.23 | dyoung-web | okay I'll try with 47k on the modded board. |
| 03:38.28 | ka6sox-office | :) |
| 03:38.38 | dyoung-web | but I'm not going to gound the extra stuff. |
| 03:38.44 | dyoung-web | that will take too long on this part. |
| 03:38.47 | ka6sox-office | yeah. |
| 03:39.27 | ka6sox-office | I need to go home...how long will yo be there? |
| 03:39.35 | dyoung-web | not long. |
| 03:39.38 | ka6sox-office | (its 30 minutes for me to get home) |
| 03:39.45 | dyoung-web | I'm just about done. |
| 03:39.45 | ka6sox-office | okay is there something I can help wiht now? |
| 03:40.13 | dyoung-web | not unless you can tell me where i can salvage a HC125 from. |
| 03:42.05 | ka6sox-office | um...dunno...haven't seen one swimming by the Islands recently. |
