 Hi everyone,

   

I use a L6234 three phase driver motor with my PSOC. To control my motor I need to get 3 PWM which are dephased 120° as you can see on the picture attached.

   

What is the best solution?

   

Thank you

The main reason I posted it was using LUT to get the 120 degree

   

phase outputs for motor drive.
