PIC24 DMA SPI
Posted: Mon Jul 17, 2017 1:16 pm
I am using PIC24HJ64GP202 with SPI DAC MCP4921 to generate an analog signal.
I have tried several approaches: CORDIC, lookup table and polynomial approximation (even ASM).
I would like to speed up the process in order to provide more samples per second to the DAC by using DMA.
Do you have any example how to setup the DMA with SPI in order to accomplish that with Flowcode 7?
