Part Number: CC2642R-Q1
Other Parts Discussed in Thread: TCAN4550-Q1, TCAN4551-Q1, TCAN4550

Tool/software:

In an automotive BLE module using the CC2642R-Q1, we are considering communication with the CAN interface.

Since the CC2642R-Q1 does not have a CAN interface, we believe that conversion is necessary.

What is your company's recommended solution for running the CC2642R-Q1 with the CAN interface?

We have an existing BLE module that contains the CC2642R-Q1, but we would like to use it as much as possible.

By the way, in similar E2E in the past, it seems that SPI is connected to TCAN4550-Q1 or TCAN4551-Q1.
(Is this the latest recommended solution?) ）

SDK: 6.30.00.84

interface: UART(SPI is wired, but the function is turned off by FW)

Application: In-vehicle meters

Hi there,

In order to interface with CAN on the CC2642 platform, we recommend leveraging a SPI2CAN transceiver like the TCAN4550, but there are also other newer options from TI that can be used as well. We have a CAN driver that works out of box with TCAN455x family though as well as a reference design that can be seen in https://www.ti.com/tool/TIDA-020032. This reference mentions AoA, but we recommend mainly referring to it from the perspective of CC2642 + TCAN4550 as a reference.

Under the Drivers Table you can refer to CAN.h and TCAN455x.h.

https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_7_40_00_77/docs/drivers/doxygen/html/index.html

You will need to update your SDK to the latest release to leverage this driver though.
