CTU_0 and CTU_1 same trigger source

alimeraj — Wed, 18 Jul 2018 08:15:25 GMT

Hi,

Is there any way to trigger CTU_0 and CTU_1 from FlexPWM_1 only?. if not how this is possible to achieve as I want to sample ADC0,1 and 2 at the same time.

Regards,

Ali

Hi,

If you need to trigger CTU0 and1 from your PWM signal.

Then you will have in CTU0 command list dual conversion for ADC0 and 1.

In CTU1 command list you will have ADC2.

Make sure CTUs triggers are executed in the same time.

Hi Peter,

thanks for coming back to my question.

The problem here is I am only using flexPWM_1 module to generate PWM and I can trigger ADC2 using CTU1 properly. the only issue I have is how can trigger the CTU0 from flexPWM_1 module or if there is any other way to sample ADC0 and ADC1 at the same time.

Ali
