subject: [PIC] PIC18F8720 Speed . . . >>I wonder what is the problem? . . . > Even worse.. most 8720s have a core bug that prevents them to work reliably over 4MHz.. . . . Wow! I did not know that. How does the PIC18F8722 work at 10 MHz external, HS PLL 40 MHz internal, as on the PIC dem HPC Explorer board? Thanks! Grinder __________________________________ Yahoo!
