analogWrite (DAC) Examples?

[ScruffR]

I've posted some PoC for playing some raw audio via analogWrite()

Photon play sampled music (wav file) using DAC

It shouldn’t be too complicated when using SparkIntervalTimer library to push the samples in a “sort of steady” pace to the two DACs. Try this one //SYSTEM_THREAD(ENABLED) SYSTEM_MODE(MANUAL) #include "SparkIntervalTimer/SparkIntervalTimer.h" #include <math.h> const int MIDPOINT = 2048; // zenter point for DAC const int MAX_VOL = 1600; // amplitude around (+/-) center point (no more than 2047! to avoid clipping) const int SAMPLE_PERIODE = 1000000/44100; /…
