[M460] CAN FD Transceiver Delay Compensation

• Application: This example code describes how to use the M460 CAN FD transceiver delay compensation function.
• BSP Version: M460_Series_BSP_CMSIS_V3.00.002
• Hardware: NuMaker-M476HJ_V1.0
  

This example code describes the transceiver delay compensation function of CAN FD. To ensure that CAN FD is sending messages at high speed, the transmitter is prevented from entering the BUSOFF. Transceiver Delay Compensation (TDC) mainly solves the problem of the physical delay of the transceiver loop on the reliability verification of signal read back.

To facilitate the understanding of the principle of TDC, this example first introduces the TDC function from the following points, and then introduces the code configuration method:

• What is a delay in sending and receiving?
• Why to use transceiver delay compensation?
• How to set the TDC?
• Case Analysis
  

This example code needs to be provided with a CAN FD debugging tool to observe the data sent and received. In this example, there is already a capture diagram of the communication signal, and if you need to verify it, it is recommended to have an oscilloscope for observation.
