QUICK START GUIDE

Chapter 1. Overview

1.1 INTRODUCTION

The PIC24F LCD Curiosity Development Board (DM240017) is a demonstration, development and experimentation platform based on the PIC24FJ128GL306 low-power, low-cost microcontroller featuring integrated segmented LCD controller. 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:

• PIC24FJ128GL306 16-bit microcontroller with 128-Kbyte Flash, 8-Kbyte RAM and up to 256 segments

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

• On-board 5-character LCD panel with backlight (8 commons, 56 segments)

• MCLR Reset button plus two general purpose push buttons

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

• Digital temperature sensor (TC77)

• 10k potentiometer

• 32.768 kHz Secondary Oscillator (SOSC) for RTCC

• Female headers for access to microcontroller I/O pins

• Coin cell battery socket and reverse battery protection for optional battery operation

• USB-UART serial communication bridge (MCP2221A) to interface with USB host/PC

• Two mikroBUS™ interfaces for hardware expansion:

- Supports a wide variety of add-on click boards™ from MikroElektronica(www.mikroe.com)

Note: The USB-UART connector does not power the board.



NOTES:



QUICK START GUIDE

Chapter 2. Board Power-up

2.1 POWERING UP THE BOARD

The board is intended to be powered through the Micro-B USB connector (USB1) in the upper left of the board. The USB-UART USB connector does not power the board. A MIC5528 linear regulator (U5) generates the +3.3V rail used by the PIC24FJ128GL306 microcontroller. The board can be powered by a CR2032 coin cell inserted into the B1 battery housing. Default jumper J9 setup is 2 and 3; this configuration can be left for power switching between the USB and the battery operation modes.

To measure the power consumption of the board, a meter can be placed between pins 2 and 3 of jumper J9 (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.

Note: The USB-UART USB connector does not power the board.

QUICK START GUIDE

Chapter 3. Getting Started

3.1 GETTING STARTED WITH THE PIC24F LCD CURIOSITY DEVELOPMENT BOARD

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

3.1.1 USB Powered Mode

In USB Powered mode, via the upper left micro-USB port, there are several different Display modes. Pressing the S2 button will cycle between each of the Display modes during USB operation. The Display modes are listed below.

1. Toggles between the text, “PIC24” and “LCD”. Toggling is done automatically by the LCD module using the Alternate Display mode of the module.

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 build_time.c file. A clean/build will update the time.

4. Displays the current temperature measured by the TC77 on the board. LCD Alternate Display mode toggles between Celsius and Fahrenheit.

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 USB/UART bridge. All the above data are displayed on the screen (time, temperature, potentiometer, etc.). The serial port needs to be set to 19200 baud, 8-bit, no parity, one stop, no flow control.

3.1.2 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-Powered mode, a CR2032 needs to be inserted in the B1 battery housing and jumper J9 needs to short between pins 2 and 3. Minimal external components are necessary to enable Battery mode, while one built-in software function will enable Sleep mode.

In Battery-Powered mode, the moon icon is displayed to indicate that it is in Battery-Powered mode. 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, while the core is still in Sleep mode. 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.

Note: The backlight only operates while in USB mode.
