Hi, I'm kind of beginner, for now a little tired because of DS18B20 refusing to give me bytes even when using default procedures from dallas appnotes. I' ll continue with that again after some rest:) For now, I am looking for some description about frequency measuring. I see a lot of PIC-based F counters with asm code, but that code usually is overloaded with display management and other stuff so are quite hard to understand. Do anybody know any reference where I could read some good description _how_ to do that. using pic16f84a for now, with gpasm in linux. -- KPL -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
