Texas Instruments TCAN4550EVM

Overview

The Texas Instruments TCAN4550EVM features a TI TCAN4550-Q1 automotive system basis chip (SBC) with integrated CAN FD controller & transceiver.

Requirements

This shield can only be used with a board which provides a configuration for Arduino connectors and defines node aliases for SPI and GPIO interfaces (see Shields for more details).

Note

This shield configuration limits the maximum SPI clock frequency to 2MHz although the TCAN4550-Q1 supports up to 18MHz SPI clock frequency. This is done to accommodate the flywires usually used for connecting the TCAN4550EVM to the board running Zephyr.

Pin Assignments

Shield Connector Pin	Function
D6	nWKRQ
D7	WAKE_LV
D8	RESET
D9	nINT
D10	nCS
D11	SDI
D12	SDO

Programming

Set -DSHIELD=tcan4550evm when you invoke west build. For example:

# From the root of the zephyr repository
west build -b frdm_k64f tests/drivers/can/api -- -DSHIELD=tcan4550evm
