How to Set Up a Timer in PIC16F877A

We have Three Timers in PIC16F877A , and here we have a look to how to setup the TIMER0 in PIC16F877A using HiTech C programm  • To set up the timer, one must first disable interrupts so that an interrupt doesn’t occur when the timer expires. • Then, enable the timer and assign the prescaler to the timer. • Establish the prescaler value, and finally, load the timer register.  Whenever the timer expires, the......

Using Timers in PIC16F877A

A timer counts pulses of a fixed, known frequency usually the system clock for the processor.Physically, timer is a register whose value is continually increasing to 255, and then it starts all over again: 0, 1, 2, 3,4...255....0,1, 2, 3......etc.  This incrementing is done in the background of everything a microcontroller does.It is up to programmer to think up a way how he will take advantage of this characteristic......
