Hi @松彬,

To configure the SPI module for the TCAN4550 chip, ensure you use the register addresses specific to the TCAN4550, not those of the 28335 microcontroller.

Configuring the SPI Module:

Access Hardware Board Settings:

• Navigate to the Hardware Implementation settings and expand the 'Target hardware resources' section.
• You will find options for SPI channels such as SPI_A, SPI_B, and SPI_C.

Set Parameters:

• Configure the mode, baud rate, pin assignments, clock assignments, and chip select settings as needed.

Data Transmission:

• Use the Tx port to send data to the TCAN4550. Ensure that the data is correctly formatted according to the TCAN4550's register specifications.
• Use the Rx port to receive data from the TCAN4550.

Example Setup: When writing to a specific register, format the data appropriately for the TCAN4550. For example, if the TCAN4550 requires a specific command and address format, ensure your Tx data adheres to this format.

Hope this helps!
