Wemos dc motor SHIELD custom firmware to drive a stepper motor in microstepping mode and torque control .
Developed code developed for STM32F030 microcontroller using GNU ARM GCC compiler and OpenCM3 libraries
I have wrote some firmware for STM32f030 (GNU ARM GCC, libopencm3),the microcontroller used in this shield for two dc motors.
Actually Interface is serial to simplify development but I will adapt it for I2C soon
TB6621FNG H-Bridges and drive 1.2A steppers.Supports microstep mode up to 128msteps,editable microstep tables change resolution on the fly and voltage control.I will upload code to github when fully checked
