Hi to all engineers, I need to generate 4 outputs like this and all 4 duty cycle Get changed at the same time. Even I had 4 hardware PWM in pic I do not think I could make it start like that. 0d 90d 180d 270d 360d |-----|-----|-----|-----| |------------| ________| |-- --------| |-- |____________| |-----------| | | |___________| | |-----------| |___________| | I use hi-tech c 18f452 any idea or recommendation Will highly appreciate. I was thinking to use array But then how to change duty cycle. The frequency is 60hz andre -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
