Quadrature pulse output generation with MC56F827 controller.

Hello all,

I need to generate the quadrature pulse (each with 90degree displacement) like the motor encoder signals. How to generate this with eFlex PWM in MC56F8247 microcontroller. What configuration should I made for this..??

I am using codeWarrior v10.6

Can anyone help me out for solving this.

Thanks in advance.

Hi,

As you know that the eFlexPWM module supports phase shift feature, so it i okay to generate the phase shift signals to simulate the PH_A and PH_B signal with PWM output signals.

I attach the example based on MC56F84789, pls refer to it.
