PIC32MX starter kit user?s guide ? 2009 microchip technology inc. ds61144d-page 35 chapter 4. PIC32MX starter kit hardware 4.1 introduction this chapter describes the hardware features of the PIC32MX starter kit. 4.2 hardware features the key features of the PIC32MX starter kit are listed below. they are presented in the order given in section 1.4 ?PIC32MX functionality and features? . you can refer to figure 1-1 on page 8 for their locations on the board. 4.2.1 processor support the PIC32MX starter kit is designed with a permanently mounted (i.e., soldered) PIC32MX360f512l processor. 4.2.2 power supply there are two ways to supply power to the PIC32MX starter kit: ? usb bus power connected to j1. ? an external application board with a regula ted dc power supply that provides +5v can be connected to the j2 application board connector that is provided on the bottom side of the board. one green led (d3) is provided to show th at the pic32 microcontroller is powered up. 4.2.3 usb connectivity the PIC32MX starter kit includes a pic18l f4550 usb microcontroller, which provides both usb connectivity and support for pr otocol translation. the pic18lf4550 is hard-wired to the PIC32MX device to provide two types of connectivity: ? i/o pins of pic18lf4550 to icsp? pins of PIC32MX ? i/o pins of pic18lf4550 to jtag pins of PIC32MX the PIC32MX starter kit currently uses t he jtag pins of the PIC32MX device for programming and debugging. note: the basic PIC32MX starter kit does not include an application board and is intended to be usb-bus powered.
PIC32MX starter kit user?s guide ds61144d-page 36 ? 2009 microchip technology inc. 4.2.4 switches push-button switches provide the following functionality: ? sw1: active-low switch connected to rd6 ? sw2: active-low switch connected to rd7 ? sw3: active-low switch connected to rd13 the switches do not have any debounce circ uitry and require the use of internal pull- up resistors; this allows you to investigate debounce techniques. when idle, the switches are pulled high (+3.3v). when pressed, they are grounded. 4.2.5 leds the leds, rd0 through rd2, are connected to portd of the processor. the portd pins are set high to light the leds. 4.2.6 oscillator options the installed microcontroller ha s an oscillator circuit connect ed to it. the main oscillator uses an 8 mhz crystal (y2) and functions as the controller?s primar y oscillator. use of an external crystal is not required for pic 32 designs. your design may use the internal oscillator, if desired. the pic18lf4550, at the heart of the usb subsystem, is independently clocked and has its own 8 mhz crystal (y1). 4.2.7 120-pin modular expansion connector the PIC32MX starter kit demo board has been designed with a 120-pin modular expansion interface, which allows the board to provide basic generic functionality now, as well as easy extendability to new tech nologies as they become available. table 4-1: starter board connector part numbers connector hirose electric pn starter board connector fx10a-120p/12-sv1(71) application board connector fx10a-120s/12-sv(71)
