Hi, I have a problem with setting etpu about mpc5777c for PWMM.

I'm trying to make Double Pulse Test Code.

so, I have to control the high-side arm and low-side arm of each 3 phase respectively.

not simultaneously.

I want to modify example code for DPT test which is considering upper condition.

*base = High side, compl = Low side

this code control the high side and low side simultaneously.

only input_base_a, input_base_b, input_base_c does work.

and input_base_a, input_base_b, input_base_c these control the high side and low side simultaneously.

maybe I think there are wrong writing channel parameters.

so I'm asking for help.

 

Thank you.

I don't understand your question too much.

Base and complementary output runs simultaneously (with certain dead time). Pay attention to AN5374
