Hi all

 

I've tried to use the TPM0 to trigger a DMA transfer to DAC, but without success.

I don't know what is the problem, but I think which is at TPM0 configurations.

 

I've attached my project. Can anyone help?

Hi Wenderson,

Please have a look and search for "DAC" and another search for "DMA" that has several post that might be helpful.

One in particular:

DAC Example with the Freedom Board | MCU on Eclipse

and bonus one:

Tutorial: PWM with DMA on ARM/Kinetis | MCU on Eclipse

Regards,

David
