can anyone please help me how to write program in TMS320F28335 Controller to control phase angle of the triac....also how to interface TMS320F28335 to optoisolator MOC3021
First you need a zero cross input signal.
Phase angle is just a delay time referred to the zero cross signal.
How to to connect MOC: There is a datasheet, application notes and a lot of reference designes around.
simply this circuit will help you. You will take zero cross detection point and fire the optocoupler depends on duty cycle.thank you for your reply....can u please provide me a link for refernce design??
