Want to use CAN API with NUCLEO-F446RE

As the title says, I wanna use CAN bus with NUCLEO-F446RE.
This is my first time using CAN bus and I don’t know what I need.
Please let me know if I need to prepare anything else additionally.

By the way, I want to run rmd-x6(motor) with F446RE.


The STM32F446RE is equipped with two CAN controllers. However for connection to CAN-Bus you need also a CAN transceiver. For example old MCP2551. This will convert Tx & Rx from controller to differential pair Can-High and Can-Low for CAN-Bus.
The Can-Bus itself is created by two wires connected by terminators (resistors with typical value 120 ohms).
For better imagination use picture below.

Of course you have to check datesheet of your motor.

Thanks for showing the diagram of how to connect.
It’s always helpful.
