I'm using Platformio with the framework-arduinoteensy v1.56 package. Any idea how I can get it to use the 1.57 beta 3? Can I install the beta 3 version into the Arduino IDE and then copy the changed files from the...
Here's my code:
#include <Arduino.h>
#include <Audio.h>
AudioSynthWaveform sinegen; // generate waveform for test
float SINE_LEVEL = 0.5; // sine amplitude (max is 1)
float SINE_FREQ = 100; // sine frequency ...
I tried a simple program where I just generated a sine wave with AudioSynthWaveform and send it to AudioOutputSPDIF3. It works fine and I can receive the S/PDIF signal and see the sine wave just fine. However, then I...
