Hi, i have a problem with the small prg for test, in 18F452 work right, but in 18F4525 not work right, see below
| Code: |
// #include <18F452.h>
#include <18F4525.h>
#FUSES NOWDT //No Watch Dog Timer
#FUSES HS
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOBROWNOUT //Reset when brownout detected
#FUSES PUT //Power Up Timer
#use delay(clock = 20 Mhz)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
