Hello,

I've got a EVAL6208PD board with Practispin ST7 based driver board.

Problem is I can't get the Practispin software to speak to the ST7 board over RS-232. The board has 5V (5.01V) coming from the 6208PD board and I get 5V on the processor and max232 chip. I adjusted R18 to 50% as the instructions call for.

All seems well except it won't communicate.

Is there some trick? I've tried two different known working cables on 3 different known working PC's.

Any ideas?

If anyone has a known working practispin and/or 6208PD board they would like to part with I'd be happy to purchase it/them.

Thanks,

Ken

Well, I replaced the 232 chip and no joy.

Is there any way to get support on this thing?

Thanks,

Ken

Looks like a bad Max232 chip. With the logic analyzer I can see data going into the 232 level converter chip, but nothing going out to the mpu.

Joy, another month to get a replacement board? I ordered a handful of 232 replacement chips as well.

Let me know please if you know anything, or can expedite a replacement, or have a working board you would part with.

Thanks,

Ken
