Post by thread:Parallax Emulator under OS/2?

>PSIM has lots of trouble under os/2. It almost always crashes for some >reason. Is this only me? Hope it is. I dunno: I haven't gotten far enough to crash yet ;-) I'm really surprised to see this kind of flakiness, though: it's clear that there's a lot of thought and talent behind the Parallax designs, and they put a lot of work into things like documentation and the "app notes" that most of their competition does poorly, if at all. You just don't expect to see a produ ct with that kind of support have diagnostics that simply say "ERROR", beep, and give up. I went through the Parallax BBS last night, and found little help or encouragement. I found someone who'd had problems with another product (the Stamp downloader) who'd solved them by enabling access to the hardware timer, but that didn't help. Worse, I downloaded a "diagnostic" routine for the ClearView that says it failed verifying that memory had been cleared. No indication of where, alas: it just said "ERROR" instead of "OK". It runs the tiny sample programs I've tried okay, but I'm worried that there's a bad RAM chip or something that'll screw up a schedule that's already impossibly tight. Interestingly, I put my serial line monitor on the CV to see if I could spot th e problem, and it complained incessantly about framing errors at every baud rate I tried. I wonder if they're running a non-standard rate... Ran
