General signal generation using data buffer fed with DMA transfers

javiercambra — Tue, 11 Jun 2013 12:21:10 GMT

Hello,

I am trying to feed the DAC buffer using the DMA. We can find a simple example in the DAC_LDD help.

I configured the devices following this example step by step, but does not work. The execution thread never reach the event DA1_OnComplete.

When configuring the DAC_LDD device in processor expert you can see that "Hardware trigger" must be Enable. But no more details are explained in this example. If I enable "Hardware trigger", then only can choose PDB, but in this example does not appear anything related to PDB, so I am little confused, and I don't know how to configure the trigger.

Any help will be apreciated.

I am using the microcontroller ColdFire V1+ MCF51QM128VLH and CodeWarrior 10.2

Regards,

Javi
