2.1 HARDWARE FEATURES

2.1.1 Microcontroller

USER’S GUIDE
The MCP251XFD CAN FD Motherboard accommodates a PIC32MX470F512H microcontroller with a 120 MHz/150 DMIPS MIPS32 controls the MCP2517FD via the SPI interface. The interrupt pins of the MCP2517FD are connected to the microcontroller input pins. The microcontroller can control the standby pin of the CAN FD transceiver on the MCP2517FD click Board using the STBY output.

M4K® core. The microcontroller

2.1.2 Clock Generator

The MCP251XFD CAN FD Motherboard uses the DSC1121, which is a Microchip MEMS clock generator, as the default clock source into the microcontroller. The DSC1121 on this board has been programmed to generate an output frequency of 8 MHz and is offered in a small 2.5 x 2.0 mm package.

2.1.3 Switches

Five push button switches provide the following functions:
• S1: Active-low switch
• S2: Active-low switch
• S3: Active-low switch
• S4: Active-low switch
• RST (S5): Active-low MCLR When Idle, the switches are pulled high; when pressed, they are grounded.

2.1.4 LEDs

Eight LEDs (D1 through D8) are available. Set the corresponding microcontroller output pins high to light the LEDs.

2.1.5 PICkit™ 3 In-Circuit Debugger connector

Connector J11 provides the footprint for a 6-pin PICkit™ 3 interface.

2.1.6 MikroBUS interface

Figure 2-1 shows the signal assignment to the mikroBUS connector. The MCP251XFD
CAN FD Motherboard is targeted to be used with the MCP2517FD click Board, but it could also be used with a variety of other click boards.

2.2 POWER SOURCES

The MCP251XFD CAN FD Motherboard must be powered using a +5V DC regulated power source. The user has two options to connect the power:
• USB connector (J14), or
• Test loops: 5VIN and GND1.
The jumper (JP1) is used to select between the power sources, see Table 2-1.

TABLE 2-1: POWER SOURCE JUMPERS

Index Description
JP1 • Powers-up the MCP251XFD CAN FD Motherboard from USB or an external
5V power supply between 5VIN and GND1.
• Short-circuit pins 2 and 3 (top and middle) to select VBUS, or pins 1 and 2 (middle and bottom) to select the external power supply.

2.4 CONNECTING THE BOARD

Figure 2-2 illustrates an example CAN FD network. The MCP2517FD click Board is
plugged into the MCP251XFD CAN FD Motherboard. A CAN FD tool from K2L is connected to the MCP2517FD click Board using twisted pair wires.
The demonstration board is powered using a Mini-USB cable. Alternatively, the board can be powered using a 5V power supply connected between 5VIN and GND1.
There are two terminations on the CAN bus:
• Two 60 Ohm resistors in series on the MCP2517FD click Board.
• A 120 Ohm termination resistor at the connector of the K2L OptoLyzer FD tool.

2.5 OPERATION

The user can write firmware for the MCU in order to create a custom CAN FD node. Check the MCP2517FD product page for the firmware API and for code examples.
The RST button ca n be used to reset the MCU. Switches S1-S4 ca n be used t o trigger the transmission of CAN FD messages to the CAN FD tool. LEDs D1-D8 can be controlled by the CAN F D tool using CAN FD messages.
All I/O pins of the MCP2517FD are easily accessible through pin headers. The differential CAN bus signals, CAN_H and CAN_L, are accessible on the
MCP2517FD click Board, or on the DB9 connector: CAN_H on pin 7, and CAN_L on pin 2.

Chapter 3. Software

3.1 INTRODUCTION

The MCP251xFD CAN FD Motherboard can be used with MPLAB X Integrated Development Environment (IDE), which is available free on Microchip’s website at
www.microchip.com. This software is used for programming and debugging the
PIC32MX470F512H on the MCP251xFD CAN FD Motherboard.

3.2 SOFTWARE OVERVIEW

The PICkit™ 3 through MPLAB X, is a low-voltage in-circuit debugger, as well as a low-voltage programmer, for the PIC32MX470F512H. In-circuit debugging allows the user to run, examine and modify programs for the microcontroller embedded in the board hardware. This facilitates the debugging of firmware and hardware concurrently. Use the in-circuit debugger with MPLAB X IDE to run, stop and single-step through programs; breakpoints can be set and the microcontroller can be reset. When the microcontroller stops, the contents of the registers are available for examination and modification.
