Hi again My PIC16873 print a number of 14 digits using the 14 "7 segment display" I did a TIMER0 interrupt routine that triggers an 4017 that selects each display (digit), connected to an 4511... When i try the WRITE_EEPROM in the main() function (only with this function), i see that my 14 "7 segment display" flicks... is there some assembly routine produced by CCS compiler that disable TIMER interrupt? Well, i'm thinking to enable a EPROM WRITE COMPLETE routine...for less overhead for CPU...correct?
