MPLAB® STARTER KIT FOR PIC24H

MICROCONTROLLERS USER’S GUIDE

Chapter 1. Introduction

Thank you for purchasing Microchip Technology’s MPLAB® Starter Kit for PIC24H Microcontrollers (MCUs). This kit is intended to introduce and demonstrate the features of the starter kit and the strong processing capabilities of PIC24H MCU devices.

The starter kit demonstrates a low-cost hardware and software solution for processing sensor signals and interfacing audio and visual displays. The board also includes signal conditioning circuitry, which helps users to perform a quick evaluation of the power of PIC24H MCUs by processing signals coming from an external sensor. In addition, the starter kit has on-board debug circuitry you can use to develop and debug your own applications without using other debug tools (i.e., in-circuit emulator or debugger).

This chapter introduces the starter kit and provides an overview of its features. Topics covered include:

•Overview

• Operational Requirements

• Board Setup

1.1 OVERVIEW

The MPLAB Starter Kit for PIC24H MCUs connects directly to the USB port on a personal computer (PC). The PC USB connection supplies communications and power to the board.

The starter kit includes debug and programmer circuitry that allows applications to be programmed onto the board’s PIC24H MCU device and then debugged, all using MPLAB IDE.

The sensor signals from an on-board triaxial analog accelerometer are routed to the fast on-chip ADC module in the PIC24H MCU for software processing. This feature allows the Starter Kit to be maneuvered by tilting. Based on the sensed acceleration due to the tilting of the board, a visual output is generated on the on-board OLED display controlled by the Parallel Master Port (PMP) module. Additionally, the speech segments are audibly produced through the on-board speaker via the output compare module as a Pulse-Width Modulated (PWM) digital waveform. This output is converted to an analog speech signal by a low-pass filter on the starter kit board. Alternatively, applications can use the conditioning circuitry to plug-in a wide range of analog sensors, grab the sensor signals through the ADC and process them.

In addition to the Recommended Reading listed in the Preface, the following manufacturers’ data sheets are also recommended as reference sources:

• Bosch Sensortec Data Sheet, BMA140 Triaxial Analog Acceleration Sensor

• National Semiconductor Corporation Data Sheet, LM4853 Boomer

1.2 OPERATIONAL REQUIREMENTS

To communicate with and program the MPLAB Starter Kit for PIC24H MCUs, the following hardware and software requirements must be met:

• PC-compatible system

• An available USB port on the PC or a powered USB hub

• CD-ROM drive

•Windows Systems.

Note 1: Only initial testing has been performed on the 32-bit Windows Vista

1.3 BOARD SETUP

Figure 1-1 shows the setup for the MPLAB Starter Kit for PIC24H MCUs. The USB connection provides communication and power to the board. As soon as the starter kit is powered through the USB cable, the preloaded demonstration starts.

MPLAB® STARTER KIT

FOR PIC24H MCU

Welcome

This chapter describes the MPLAB® Starter Kit for PIC24H Microcontrollers demonstration that is preloaded on the PIC24H MCU device, which showcases the multitasking of accelerometer sensing, the OLED display, speech playback, and the switch press monitor. This software application demonstrates how to use the MPLAB Starter Kit for PIC24H MCUs for signal capture and processing of the sensor signal, speech decoding and playback, and controlling the OLED display.

A detailed explanation of the starter kit hardware is provided in Chapter

4. “Hardware”. Topics covered include:

• Running the Demo

• Understanding the Demo

• Other Demo Code Examples

2.1 RUNNING THE DEMO

T o run the demo, follow these steps:

1. Power-up the starter kit by connecting the board to the USB port of a computer. You should briefly see a pop-up message in the system tray that states (1) new hardware has been found, (2) drivers are being installed, and (3) new hardware is ready for use. If you do not see these messages and the starter kit does not work, try reconnecting the USB cable. If reconnecting the USB cable does not work, refer to Section 3.8 “Troubleshooting”.

When powered up, an audible welcome message is played while simultaneously displaying the Start-up screen on the OLED display (see Figure 2-1).

After the start-up exercise, the Home screen appears on the OLED display, as shown in Figure 2-2.

The Home screen has four cells from which to choose: Accelerometer (Acc.) Graph, External (Ext.) Sensor, Orientation and Games. The starter kit can be maneuvered by tilting it about the X and Y axes. Based on the direction of tilt, one of the four cells is highlighted for selection. Switch S1 or S2 can be pressed to select the highlighted cell.

FIGURE 2-2: STARTER KIT HOME SCREEN

2. Selecting the Acc. Graph cell starts the application, which captures the triaxial outputs of the accelerometer and displays them on the OLED display as a graph, as shown in Figure 2-3. Switch S1 or S2 can be pressed at any time to return to the Home screen.

FIGURE 2-3: ACCELEROMETER GRAPH

3. Selecting the Ext. Sensor cell (see Figure 2-4) starts the application, which captures the output of the external sensor that can be plugged-in at points TP12 and TP11.
