esp-idf-m5stack-speaker

Example to ring the speaker of M5Stack with esp-idf. I ported from Arduino core for M5Stack.

The buzzer needs enough current. If there is not enough current, Brownout will occur. ESP32 has a built-in brownout detector, which is enabled by default. Brownout detector can trigger system reset if supply voltage goes below safe level.

Brownout detector was triggered
