> Putting tech Support Asside... What makes Zilogs Inferior to PICs.. or vice > versa??... Well, the basic architecture of the Z8 is nice, all ram is registers, and all instructions work in all registers. So, imagine a pic with 200 W registers. Also, any pair of registers is a 16 bit pointer, if you want it to be. The AVR sits inbetween, with 32 registers, and most instructions work on all registers. On the down side, the Z8 gets one instruction per 12 crystal clocks (12 MHz = 1 mips) where the Pic gets one per four (4 Mhz = 1 mips) and the AVR gets almost one for one. (some avr instructions take two, and there are rare ones that take more) When I last worked with them, the Z8 line didn't have any flash based parts, it was OTP, "Piggyback rom", or mask rom only. Their emulator was totally useless, however Signum's emulators worked nicely. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
