UAVCAN for STM32 Arduino is a simple UAVCAN libcanard (https://github.com/UAVCAN/libcanard) example for the Arduino IDE (https://www.arduino.cc/) running on STM32 development boards.
This example requires the use of Arduino STM32 core package (https://github.com/stm32duino/Arduino_Core_STM32).
It has been tested on STM32F103C8 and STM32F303CC development boards, using Arduino IDE v1.8.5 with Arduino Core STM32 v1.8. CAN bus commands were generated using UAVCAN GUI (https://uavcan.org/GUI_Tool/Overview/) v0.9.0 running on 64 bit Win 10.
