Guys
Did a lot of homework and got incremental and HBridge
controller working for my DC Geared motor control
system.
Now I am finding reason to focus on the firmware, but
am really confused if I can get the
PIC16F877A/PIC18F4550 to output 2 PWM at SAME
frequency (the freq at which the HBridge is driven)
but at 2 different duty cycles (to control the RPM of
the two motors)...
Is is possible to have two different duty cycles of
the same freq from two different pins of a PIC.
I am obviously asking about hardware PWM as a software
solution would tie up the PIC too much AFAIC...
Do get back.
Vimal
