STM32 Servo controller

STM32Servo

STM32Servo turns your STM32 micro-controller into a multi-channel servo controller with some additional goodies. This version was specifically written for the Blue Pill but can be easily adopted to other boards. The firmware is controlled via a simple set of UART commands.

You can find a demonstration video on YouTube.

This firmware was originally written for a robot project but I have never had the time to complete it :(

Basic Features:

• Servo calibration. Sets the PWM length for 0° and 180°. I might change this in the future to make it more flexible!
• Timed PWM interpolation. E.g. you can turn a servo from 45° to 170° within the next 2,5 seconds.
• Each servo has it's own time line. They are completely independent.
• Currently supports up to 24 servos in parallel. This can be easily extended. You can virtually turn every pin of your micro-controller into a PWM generator.
• Enabling/disabling servos on the fly.
• Adoptable to other micro-controller boards. The servo code is controller agnostic and the rest is done using libopencm3 + PlatformIO.

The example directory contains a simple test console and an interface class for the servo controller. Have fun!
