Reference design to demonstrate CAN FD communication on Hercules™ microcontrollers


Design files


This reference design showcases controller area network, flexible data-rate communication (CAN FD) on Hercules™ TMS570 microcontrollers using the TCAN4550 CAN FD controller. The interface between the TMS570 and the TCAN parts is done through a serial peripheral interface (SPI). This example can be used to implement CAN FD communication on any Hercules™ microcontroller that does not natively support CAN FD.

  • Demonstrates CAN FD communication on TMS570 microcontroller
  • TMS570LS1224 microcontroller connected to TCAN4550 controller to emulate a CAN FD network node
  • Included application code demonstrates CAN FD communication between two nodes
  • This reference design is tested and includes firmware, demo and a Getting Started guide
