T-Panel_V1.3 CANFD

Operating System

T-Panel_V1.3 CANFD

Description

Can you give some clarification on the CANFD version of the board? Is it CAN (Controller Area Network) or is it CAN FD (Flexible Data)? If it's CANFD, I gather that TWAI isn't compatible with CANFD?

I don't see any other reference to CANFD in the github.

I want to use the T-Panel to read CAN messages in a car, and display info derived from it. Does the T-Panel both send and receive CAN messages? Or does it require an external board?

@TobyLies The T-Panel CANFD version can automatically send and receive CAN messages. Normal communication requires that your other device also supports the CAN protocol. The following link provides an explanation of the CAN bus. CAN bus

You can refer to the following sample program to use CAN. CAN T-Panel_Test_V1_2

What CAN transceiver do you use on this board? I see nothing on schematics.
