CanOpenSTM32 | CANopenNode on STM32 microcontrollers

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. The STM32G0C1E-EV Evaluation board is a high-end development platform for the STM32G0C1VET6 microcontroller. It has many features including two CAN FD controller and physical layer on board. You don't 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 CN12. FDCAN IP block is same for any STM32G0xx MCU family, hence migration to your custom board should be straight-forward. Nucleo includes an arduino compatible headers which can be used to add MAX33040ESHLD to it and this bundle provide the minimum required components to establish a CAN communication and CanOpenNode on top of that. This project is tied to the CubeMX configuration, so it is up to the user to provide compatible configuration using CubeMX (bitrate, interrupt activiation and etc). Have a look at STM32CubeMX configuration file for pin mapping.
