BeagleConnect QuadESC: 4-Channel BLDC Controller · File : uart-dshot-debug.ino · Language : C · Use case : Configurer l'UART pour le débogage série ou la communication DShot bas niveau.

UART configuration for serial echo, useful for debugging or DShot protocol.

Uses 'arduino_serial' alias. Enables RX interrupts. Echo code tests serial link. For DShot, replace echo with precise pulse generation via PWM/Timer.
