TMS320F28379D: Generate PG signals from an internal variable representing rotor position

Part Number: TMS320F28379D

How to generate PG signals from an internal angle variable?

The eQEP module takes encoder signals (A, B, Z) as input to calculate rotor position and frequency. I want to generate encoder signals (A, B, Z) using the DSP from an internal variable representing rotor position. Any suggestions of how to do this?

    Hi Yao,

    Can you provide more details on the application you are needing this for? Are you looking to generate the ABZ signals using the ePWM modules? We don't have any documentation or examples covering this implementation, but to convert this information for the output of QEP signals, you would need to translate this rotor position information to period information which you can feed into the PWM module to output

    Regards,
