PSoC-1 page below the first paragraph= has the link to two kits I mentioned: 'An Overview on PSoC 1 Kits =96 Clic= k Here '. I couldn't find it by any other route. I'm managing to get a bit better at navigating the site, but it's still rather frustrating. Latest annoyance, I've been going through the PSoC Designer video tutorials to re-familiarize myself with the IDE. I spent a bunch of time watching the "System View" tutorials, happily started up the IDE, then found out that as of the last couple of versions that part of Designer has been removed.

Spatial placement is interesting, but for the initial version I'll be happy with sending some things left, others right, and the remaining in both. > I'm not sure if the 28-pin devices will handle all the inputs you need pl= us a stereo pair for outputs. You may need to establish a basic design then= look for another device that supports all the requirements. I'm starting to look into that now, but it should be close. I'm modifying things a bit from what the original app note is for. He's got a mono output that I don't need, but I do need an additional mic output driver with at least two (ideally 3) outputs, one input. I think I can free up enough analog blocks but I have to check that I'll be able to route the signals in and out of the chip. > I'd be happy to kibbutz and advise for credit in any published article.

I'm not really sure that anyone else would actually be interested in such a specific use device, but I'm happy to share how it all goes! My next task will be coming up with a low powered headphone amp that's powerful enough to drive my in-ear monitors successfully. Also...starting to play more with the PSoC. Thank you!
