2. Re: DMA transfer to a gpio data register
hsouders_1431076 Apr 4, 2016 3:57 PM (in response to hsouders_1431076)Thanks. I think I actually figured it out on my own after playing around for a bit. It looks like I need to configure the transfer for 32 bits, and then the top 24 bits get dropped. Weird, but I guess that's how it works when dma-ing directly into gpio registers?
Sample code is attached if anyone wants to take a look or has any thoughts.
