How to DMA without PEx

wendersonolivei — Fri, 08 Aug 2014 11:00:38 GMT

Hi all,

I was trying to configure the DMA module at low level (without PEx or PDD). But i don't got it, something is missing..

Someone who knows how to configure it can help?

I've attached my project, with PEx bean (working) and the low level code.

Thanks

You can get DMA code for the KL25 at KINETIS Project Code (all available as source code with KL and K compatibility and no need to generate for particular processors).

It includes memory to memory (memcpy() and memset() optimised for maximum performance based on aligned DMA), as well as UART and ADC/DAC DMA.

Furthermore it allows the DMA operation to be simulated so that it can be studied and any errors easily detected ad corrected before final tests on HW.
