TCAN4550-Q1: TMS570 SPI abstraction layer and TCAN4x5x API

Other Parts Discussed in Thread: MSP430FR6989, , TCAN4550

Hi Team,

For my new automotive project, I m using CC2642 MCU and TCAN1550 CAN controller, and through SPI interface, so we can achieve the CAN communication.

In TI website, Texas Instruments provides Microcontroller Abstraction source code but it is important to note that the SPI Abstraction Layer driver is developed for a MSP430FR6989. But currently for my project i want SPI Abstraction Layer driver  for a CC2642 MCU, could you please suggest, where shall i get this SW. 

Kindly help me to get SPI Abstraction Layer driver for CC2642.

could you please tell me where can i get TCAN4x5x API doc

As per software user guide TCAN4x5x Software Users Guide.pdf , there is a SPI abstraction layer and TCAN4x5x API  available , where can we find these libraries and API information. 

We are planning to use TCAN4550 for our new ADAS project.

Other wise suggest the method or steps to implement SPI Abstraction Layer driver for CC2642.

    Hello Anilkumar,

    As you have already noted, the reference API code available for the TCAN4550-Q1 was developed using the MSP430FR6989 as the reference processor.  (TCAN4550 Demo Software)

    The Section 6.2 of the TCAN4x5x Software Users Guide discusses what changes need to be made to the SPI related functions when a different processor is used. 

    This was assigned to the forum that supports the TCAN4550 and I can address your device related questions.  But if you need help with the CC2642 programming and how to modify their SPI related driver code, I will need to move this thread to the processor forum so that it can be addressed by the CC2642 support team. 

    Would you like me to reassign this thread?

    Regards,

    Jonathan
