Quick Start Guide

Overview

The PIC24F LCD and USB Curiosity Development Board (DM240018) is a demon­stration, development and experimentation platform based on the PIC24FJ512GU410
low-power, low-cost microcontroller. The board has a built-in programmer/debugger and
provides all the hardware necessary to get started developing a complete embedded
application. Some key features of the board include:

• PIC24FJ512GU410 General Purpose USB, 16-Bit Microcontroller

• PICkit™ On-Board (PKOB) Circuit implements Basic Programming/Debugging

- CDC (UART over USB), supports 115.2k 8N1 only

• On-Board 5-Character LCD Panel with Backlight (8 common, 56 segments)

•MCLR

• Micro-B USB for developing PIC24FJ512GU410 USB Device Applications

• Red/Green/Blue (RGB) LED plus Two General Purpose Indicator LEDs

• Digital Temperature Sensor (TC77)

• 10k Potentiometer

• 32.768 kHz Secondary OSC for RTCC

• Female Headers for Access to Microcontroller I/O Pins

• Two mikroBUS™ Interfaces for Hardware Expansion

• Supports a Wide Variety of Add-On Click boards™ from MikroElektronika

Board Power-up

The board is intended to be powered through the Micro-B USB connector (J20 PKOB4) in
the upper left side of the board. The J16 USB connector does not power the board, but is
used for developing USB device applications with the PIC
MIC5528 linear regulator (U12) generates the +3.3V rail used by the PIC24FJ512GU410
microcontroller. The board can be powered by a CR2032 coin cell inserted into the B1 battery
housing. The default jumper J9 setup is 2 and 3; this configuration can be left for power
switching between USB and Battery Operation modes.

To measure the power consumption of the board, a meter can be placed between pins 2 and
3 of jumper J1 (that goes to the battery housing). To measure the current of the CPU, cut the
trace on the bottom of the board under jumper J1 and place a meter between the two pins.

Getting Started

The preprogrammed “out-of-box” demo project for the PIC24F LCD and USB Curiosity
Development Board has two main modes of operation, USB Powered and Battery-Powered.

USB Powered Mode:
In USB Powered mode, there are several different Display modes. Pressing the S2 button

will cycle between each of the USB Display modes. The Display modes are listed below.

1. Toggles between the text,

2. Displays the 12-bit value of the potentiometer.

3. Displays the build time of the project. Note that this is the build time of the

4. Displays the current temperature measured by the TC77 on the board. LCD Alternate

file. A clean/build will update the time.

Display mode toggles between Celsius and Fahrenheit.

Note: The backlight only operates while in USB mode.

The potentiometer will change the intensity of the RGB LED channel that is
currently active. Switch S1 will change which channel is currently active.

A COM port can be opened to view the data through the J16 USB connection.
All of the above data are displayed on the screen (time, temperature,
potentiometer, etc.). The PIC MCU’s USB peripheral is acting as the UART-USB
bridge.

Battery-Powered Mode:
If the USB power is disconnected, the board can run from a battery backup and

will go into Battery-Powered mode. In order to run in Battery mode, a CR2032
needs to be inserted in the B1 battery housing and jumper J9 needs to short
between pins 2 and 3.

In Battery-Powered mode, the moon icon is displayed. The battery status icon
indicates the current battery status.

The time will be displayed on the screen. The “:” blinks using the LCD module’s
blink feature. The CPU does not need to wake up to update the screen for the
“:”. The CPU wakes up once a minute in this mode to update the time on the
screen. LED1 will blink while the CPU is awake. The CPU will also wake up when
the USB power is detected.

All other functionality from the USB mode is disabled.

Note: The backlight only operates while in USB mode.

LCD Operation

Backlight operation is dependent on the USB 5V supply; the LCD backlight is
disabled during Battery-Operated mode.
