Quick Start G uide

Overview

The PIC24FJ256GA7 Curiosity Development Board (DM240016) is a demonstra­tion, development and experimentation platform based on the PIC24FJ256GA705
low-power, low-cost 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:

• PIC24FJ256GA705 general purpos e, 16-bit microcontroller

• PICkit™ On-Board (PKOB) circuit implements basic
programming/debugging ability

•MCLR

• Red/Green/Blue (RGB) LED + two general purpose indicator LEDs

• 10k potentiometer

• 32.768 kHz crys tal

• Female headers for access to microcontroller I/O pins

• Circuit prototyping area

• Two mikroBUS™ interfaces for hardware expansion

Board Power-up

The board is intended to be powered th rough the mic ro-B USB connector (USB1).
A MIC5528 linear regulator (U5) generates the +3.3V rail used by the
PIC24FJ256GA705 microcontroller.

Getting Started

Microchip Technology provides several example projects that can be used to get
started with the PIC24FJ256GA7 Curiosity Development Bo ard. The source code,
the MPLAB
(MCC) can be obtained from:

http://www.microchip.com/pic24fj256ga7curiosity
http://www.microchip.com/curiosity
http://www.microchip.com/mplab
http://www.microchip.com/xc16
http://www.microchip.com/mcc

The preprogrammed “out-of-box” demo project for the PIC24FJ256GA7 Curiosity
Development Board impleme nts an RGB color mixing applicat ion. 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.

In order to use the PKOB programmer/debugger within the MPLAB X IDE (v3.55
or later recommended), select:
