I have a MCP4725 wired up to a T4 on pins 16 and 17 and it "works" but I may have chosen the wrong thing. What I want to do is have non-blocking way to play short (1 sec or so) audio samples. I was thinking I could use DMA over I2C but apparently there is no library to do that on the T4 (did not see anything dma related in wire). Do I need a I2S device? The amp the dac would be driving has an input range of +/-300mv.
