SPI to control register data transfer using DMA
Could I use DMA for read a 16 bit data from a master SPI and transfer the data on two 8 bit control registers?
Since the SPI works at very low frequency (1MHz), I need to update both registers only at the end of the reading procedure.
It is enough only one DMA channel or the procedure requires two different transfers ( SPI->RAM, RAM->control register), thus two DMA channels?
Thanks in advance
