4.2.4
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 circuitry 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
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
The installed microcontroller has an oscillator circuit connected to it. The main oscillator
uses an 8 MHz crystal (Y2) and functions as the controller’s primary oscillator. Use of
an external crystal is not required for PIC32 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
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 technologies as they become available.
