PWM and PIC Microcontroller

[jacks]

Hello Friends

I am convinced I need to use the PIC Microcontroller for my H-Bridge circuit and motor. I have been reading the datasheet for PIC16F84A. I got my circuit working, using a function generator for PWM to speed up my motor.

I am not sure how to program the PIC to work as a PWM for my H-Bridge circuit? How do I translate the analog to digital? The pic has a pwm embedded in it. Thanks

The old 16F84A doesn't have hardware PWM. The better 16F628A has one channel and many 28pin PICs have two.

Hi Blueroomelectronics

Thanks for your reply. Is the 16F628A easy to program and do you know of a best site with good tutorials?

It's the same instruction set as the 84. I have links on my site to many great PIC pages. Nigels site is great for getting started.

Thanks, I will go to your site now.
