SPI to CAN FD SBC + LIN Transceiver BoosterPack User's
The SPI to CAN FD SBC + LIN BoosterPack™ features the TCAN4550-Q1 CAN FD controller with
integrated transceiver providing microcontrollers without an integrated CAN FD controller, or those
needing additional channels, access to CAN FD applications through a SPI interface. LIN applications can
also be developed using the TLIN2029-Q1 fault protected LIN transceiver and the MCU UART port
making this BoosterPack an ideal starting point for any CAN FD or LIN system.

However, by default, 0-Ω resistors have been placed across the choke pins to connect the CANH and CANL pins of the TCAN4550-Q1 device with the rest of the CAN bus connectors and features of the BoosterPack. To add a choke to the BoosterPack, simply remove resistors R10 and R15 from the BoosterPack and install the choke in their place.

    EN floats. Firmware The TCAN4550-Q1 CAN FD controller with integrated transceiver SBC supports classic CAN and CAN FD communication through a SPI interface and incorporates the common Bosch_M_CAN controller. The provided firmware examples helps users configure their MCU for CAN or CAN FD communication without a deep understanding of the CAN/CAN FD protocol.

  • Page 15: Visual Representation Of Mram Allocation

    NOTE: No segment can be equal to 0 tq, yet this is a valid value to be input to the TCAN4550-Q1 registers for the CAN bit timing. Therefore the TCAN4550-Q1 interprets the values input to the registers as 1 greater than the input value.

The controller then tries to send the messages on the bus at the first available opportunity given the arbitration rules and message identifier priority level as compared with the other messages being transmitted from other nodes at that moment.

    In the example firmware, the message contents can be seen through the use of the debugger by setting a breakpoint on the line of code following the line where the message is read from the TCAN4550-Q1. The following line of code is the line that reads message from the TCAN4550-Q1.

    For non-AutoSAR applications this code library provides all of the building blocks to use as a starting point for any system development. This API abstracts TCAN4550-Q1 function calls to call upon a SPI Abstraction Layer function, allowing the user to quickly change code to a different microcontroller by only changing the code which controls the SPI peripheral.
