BeagleConnect QuadESC: 4-Channel BLDC Controller · File : am13e23019-gpio-led-blink.ino · Language : C · Use case : Faire clignoter une LED via GPIO pour valider l'initialisation du système.

Minimalist example of TI SDK GPIO driver initialization to control a digital output.

Uses TI AM13E2X SDK. Verify the physical LED pin on the BeagleConnect Torque schematic. Compile with the SDK makefile and flash via JTAG/SWD. Requires prior system clock initialization.
