Hi all, I just tried to use half bridge mode of ECCP in PIC16F616 to build a SMPS. Its integrated comparators used for short circuit protection and voltage error correction. All are working but PWM adjustment resolution is low. Method used to adjust pwm duty cycle is changing PWM1CON register value so that to change dead band delay. Any one have idea to get better resolution?
