i am playing around with these 40pin pics .
i am trying to control three 12v DC motors (not steppers , not servo) over h-bridge, with no feedback.
the 18F4431 has power pwm module that comes build in to provide up to 8 channels in complemntry mode
however i read the datasheet on the power pwm module and cant understand how to work with this module easly.
i downloaded several application notes, but most of them are reffering to ccp pwm .
i will appricate any help or any step by step instruction on how to do that
Here is a code snippet to initialize the PWM module. It is not yet been tested since I had set that project aside for now. I hope it helps you get started.
You define the value of PTPER_VAL to set the PWM frequency. See table 17-2 of the PIC18F4431 datasheet for the suggested values.
