Overview
The PIC24F Curiosity Development Board is a demonstration, development and
experimentation platform based on the PIC24FJ128GA204 eXtreme Low Power
(XLP) microcontroller. The board has a built-in programmer/debugger and provides
all of the hardware necessary to get started developing a complete embedded
application. Some key features of the board include:
• PIC24FJ128GA204 general purpose, 16-bit microcontroller
• PICkit™ On-Board (PKOB) circuit implements basic
programming/debugging ability
• MCLR Reset button + two general purpose push buttons
• Red/Green/Blue (RGB) LED + two general purpose indicator LEDs
• 10k potentiometer
• 32.768 kHz crystal
• Female headers for access to microcontroller I/O pins
• Small prototyping area + Bluetooth® LE radio footprint
• mikroBUS™ interface for hardware expansion
Board Power-up
The board is intended to be powered through the micro-B USB connector (USB1).
An MCP1703 linear regulator (U6) generates the +3.3V rail used by the
PIC24FJ128GA204 microcontroller.
Getting Started
Microchip Technology provides several example projects that can be used to get
started with the PIC24F Curiosity Development Board. The source code, the
MPLAB® X IDE, the XC16 C compiler and the MPLAB Code Configurator (MCC)
can be obtained from:
http://www.microchip.com/curiosity
http://www.microchip.com/pic24fcuriosity
http://www.microchip.com/mplab
http://www.microchip.com/xc16
http://www.microchip.com/mcc
The preprogrammed “out-of-box” demo project for the PIC24F Curiosity
Development Board implements an RGB color mixing application. In the demo, the
potentiometer can be used to adjust each color channel intensity, independently,
while the push buttons are used to select the channel to be adjusted.
