Ok. Thanks a lot. I'm gonna look into your link and try that PICBasic. Damn. 16f84s are still in mass production here. I feel like a caveman. Hehe. But still I'm wondering, do you think it's possible to communicate 2 of those serially with a well written program? And what PIC do you suggest I use? I've read people suggesting PIC16f628 in forums. Is it good? Thanks again. I really appreciate your reply.
