Some questions on motor speed control

ADCIN 0, CCPR1L ' Read Pot, and put the result directly to PWM register. Assuming 8-bit adc reading

Hi sayzer, thanks for the time. I settle to use L298 because that's what I have right now. Can you help me check my connection between the PIC and L298..is this okay? Like I said in first post I was able to control the L298 but without PWM conttrol on PortB. Now I want to apply the PWM on PortC.1, but not really sure how is the connections...

thanks in advance,
joe

I never used L298, I always made my own H-Bridge.
Using PWM on L298, some people drive Enable pin by PIC's PWM output. I am not sure how effective this is.
I would, however, use 7408 AND gate (two gates, one pin common to PWM pin), others to direction pins.
This way, you always have a PWM channel, and also have the control of the direction.

thanks, sayzer. I will try to take time to study it.
