PIC16F877A, PWM Pluse Generating for controlling switch

[rohan0630056]

pic16f877a pwm

Hello, Im new here...... can anyone tell me the MPLAB code for below project:

"PWM based DC-DC converter"

Description: In this project i need to do 2 thing: generating PWM pulse by comparing a changeable DC* with a sawtooth.

** Changeable DC is come from an outside world analog signal which i need to convert with ADC


"PLZ HELP ME............"

sawtooth signal in pic16f877

There are two possibilities
1- Digitize you analog signal and generate PWM from CCP module
2- use Comparator module it will generate PWM but that is not so much 'controllable'

Will you please tell the Frequency of PWM, Analog signal type etc.

see this topic, it also address using of PIC for PWM DC DC Converter
