ESP32_DSHOT.ino

/*==========================================================================================
Demo Progam for: ESP32_DSHOT - ESP32 Arduino library for bidirectional DSHOT

Starts DSHOT300_BIDIR and DSHOT300 on pins 23 and 21 and cycles thottle.

Tested on ESP32 with Arduino-ESP32 v2.0.14 (ESP-IDF v4.4), might work on other ESP32 variants with modifications.
