STM32L476XX CAN functionality Support?

I have purchased a 

https://os.mbed.com/platforms/ST-Nucleo-L476RG/

 board for evaluating STM32L476XX MCU. However I am interested in the CAN functionality provided by the MCU and my question is do I need CAN transceiver(for example an MCP2551 chip) to be able to communicate with a CAN Device or the CAN functionality available out of box with

STM32L476XX 

MCU is sufficient to communicate with a CAN Device.

Thanks,

Ajay.

Usually you would need the line translator to talk to any normal CAN device.

but between nucleo boards for example, a diode circuit would suffice.

To start communicating on CAN, I suggest you purchase a transceiver and work on the receiver code first.

I used the CanDo unit.

Pro-Tip: Look at circuits used on EVAL series boards for examples of peripherals not provided on the NUCLEO boards.

Where is example code for STM32 MCU CAN bus master mode?

'its in the repository ' may or may not be true...

I would search for Canbus stm32L examples code in google...

We are here to help when you get stuck, it can take days to work on 1 small issue.

There is a CAN Tx/Rx example for the STM32L476 here

STM32Cube_FW_L4_V1.11.0\Projects\STM32L476G-EVAL\Examples\CAN\CAN_Networking

The examples demo basic functionality, if you're looking for more you might have to dig a bit.
