eFlex PWM Using DMA Not working

OnoFame — Wed, 28 Sep 2022 07:36:00 GMT

Hello everyone, I am having issues getting eFlex PWM to work on the MKV44F128VLH16

The packet length is 384 and it is 16-bit. I need to send this to the register continuously.

Can anyone help me please?

Thank you so much for your interest in our products and for using our community.

I am sorry to inform you that so far we do not have that specific example code with the PWMA/eFlexPWM module.

The closest I've found to what you're looking for, which you could use as a reference, are the application notes AN5121 and AN4598, as well as the SDK example evkbimxrt1050_qtmr_inputcapture_outputpwm_dma. Although I must clarify that they are for other devices.

Please excuse any inconvenience this may cause you.

Have a nice day!
