Today I’m going to work on getting the final piece of the ARM firmware settled: DMA. Right now, I’m acquiring samples from the SSP manually but I won’t be able to process data if I’m wasting all my time grabbing samples so I need to pass that task to the DMA controller. The unknown at this point is how the DMA controller affects to slave select line because I need it to toggle every 8 bytes to use it as the start acquisition line on the ADC.
