Hi, I've just started a project using a PIC12F675. Just to get started I'm trying to drive all of the port pins high, but I'm having no success. I'm aware that the ports have multiple functions and need to be set up. I don't seem to have nay control over any of the pins. I'm using HI Tec PICC lite embedded into MPLAB 8.1. My code is: /* PIC 12F flash.c */ #include "pic12f6x.h" vo...

vaishnavi236, Well first, the 12F675 does not have hardware PWM. It does have a Timer1 and Comparators, but no PWM. I can explain the functions of the bits in T1CON, but that won't help the PWM situation, or more precisely, the lack of it. Secondly, you say you want TON = 10% and TOFF = 90%. What exactly is 'T'? Lastly, what exactly are you trying to accomplish with this program? Le...
