What do people build with it?

USE CASE 1

Build precise brushless motor control for a robotics or drone project using STM32 hardware directly.

USE CASE 2

Add real-time multitasking to a motor control system with FreeRTOS instead of Arduino's simple loop.

USE CASE 3

Scale up to more motor channels or a more powerful STM32 chip for higher-power applications.

USE CASE 4

Use hardware encoder and CAN bus features that Arduino abstractions normally hide.

What is it built with?

CSTM32FreeRTOSCAN bus

Copy-paste prompts

Prompt 1

Explain how this project rewrites SimpleFOC to use STM32 hardware features instead of the Arduino abstraction layer.

Prompt 2

Walk me through how FreeRTOS is used in this repo to run motor control tasks in real time.

Prompt 3

Show me how to add an extra motor channel to this project if I have a spare hardware timer.

Prompt 4

Help me understand the configuration file that documents the exposed input/output pins on this board.
