在通过SPI配置TCAN4550芯片的寄存器时遇到了如下问题:
1.对于SPI模块中,使能寄存器地址,时28335的寄存器地址还是TCAN4550的地址
2.如何通过simulink SPI模块配置从机

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!
