This is a library dedicated to stepper motors for Arduino and microcontrollers. Since it is written in C language, it can be used with PIC microcontrollers such as 16F1827.
This will not work with Arduino IDE 1.6.5 (or below) or with non ESP32-S2/S3 devices (e.g. Arduino UNO, Arduino MEGA, etc.). To use this library you need to have Arduino core for the ESP32 installed.
