CANopenNode on STM32 microcontrollers.

CANopenNode example for STM32

CANopenSTM32 is a CANopen stack example running on STM32 microcontroller.

How to run demos

Examples are developed in STM32CubeIDE tool, official ST development studio for any STM32 microcontroller. You can directly open projects run prepared examples on the board.

Currently used board is STM32H735G-DK. It has many features of STM32H7xx series and includes 3 CAN transceivers on the board. You do not need any additional hardware to connect to existing CAN network. It also includes built-in programmer and virtual COM port for communication, hence evaluation is quick and easy.

CanOpen demo works at FDCAN1 port. Use connector CN18.

FDCAN IP block is same for any STM32H7xx MCU family, hence migration to your custom board should be straight-forward.

Features

• Runs out of the box on STM32H735G-DK board
• Bare metal or FreeRTOS operating system examples
• FDCAN1 (CN18) hardware is used for communication at 125kHz
• CANopen LED control is well integrated
• Debug messages are available through VCP COM port at 115200 bauds
• Can be used as a reference code for end product
