MCP251XFD CAN FD主板

The MCP251XFD CAN FD Motherboard provides a simple, low-cost board to evaluate the MCP2517FD family of devices. The board features one mikroBUS™ socket to accommodate the MCP2517FD click Board.

The MCP251XFD CAN FD Motherboard together with the MCP2517FD click Board can be used to implement a CAN FD node.

The MCP251XFD CAN FD Motherboard contains a PIC32MX470F512Hmicrocontroller with a Service Provider Interface (SPI) peripheral. The microcontrollercontrols the MCP2517FD via the SPI interface.

A firmware Application Program Interface (API) is available for rapid applicationdevelopment, which is written in C programming language for

HarmonyIntegrated Software Framework. It can be easily ported to other microcontrollers.
