CAN FD To USB Gateway Project With Teensy 3.2 And Microchip MCP2517FD CAN FD Controller
Our Teensy 3.2 With CAN FD Breakout Board provides all the components needed to create your CAN FD to USB-Micro Gateway. The board comes with the Microchip MCP2517FD CAN FD controller, while the Teensy 3.2 provides the USB connection. It also has an onboard 5 VDC regulator and reverse-voltage protection.
The MCP2517FD is a cost-effective and small-footprint CAN FD controller that efficiently connects to the Teensy CPU via an SPI interface. Consequently, the CAN FD channel offers an extension to a microcontroller that is either lacking a CAN FD peripheral, or doesn’t have sufficient CAN FD channels.
The MCP2517FD supports both, CAN Bus data frames in the Classical format (CAN2.0 A/B) and CAN Flexible Data Rate (CAN FD) format.
All that is needed to complete the gateway application is the firmware, which is available as a download from the Github website. The protocol software converts CAN FD data into ASCII to be transmitted per USB and vice versa. Also, the USB side can send ASCII data for CAN FD port setup (open/Close channel, CAN FD Baudrate, etc.) and request hardware and firmware versions.
There is also a Youtube video, explaining the setup and use of the gateway.
