skyyu.zhang's example code from https://github.com/skyyuzhang/UAVCAN_NODE_FreeRTOS reshaped as a PlatformIO STM32Cube project.

keywords: STM32F103C8, CAN bus, UAVCAN, libcanard, PlatformIO, STM32Cube, FreeRTOS

• tested on STM32F103C8 ("Blue Pill")
• CAN RX: pin A11
• CAN TX: pin A12
• bus speed: 250kbaud (you can change CAN_SPEED in uavcan.h)

Build and upload using PlatformIO as usual.

After connecting to your PC's CAN bus hardware, you should see new UAVCAN node named skyyu.node.demo with id 50 in UAVCAN GUI Tool.

The code uses original skyyu.zhang's FreeRTOS version because there's no FreeRTOS for stm32cube platform in PlatformIO. I have placed it in lib/FreeRTOS-stm32cube directory for better reuse but FreeRTOSConfig.h is placed here too which is not a good solution. I could probably use some includedir black magic but it would not be much better solution IMHO...
