UNDERSTANDING THE DEMO
Starter Kit for PIC24H Microcontrollers User’s Guide
The PIC24H MCU device on the starter kit is pre-programmed with the main application
demonstration. The CD that accompanies the starter kit also contains the main appli-
cation code. As shown in Figure 2-14, this sample application uses the board to cap-
ture the triaxial acceleration signals from the accelerometer, and plays speech
messages through the speaker with a visual display on the OLED display.
The board also features conditioning circuitry that provides the user the flexibility of
plugging in a wide range of sensors and performing signal processing on the captured
sensor signals.
Detailed descriptions of the basic modules are provided in Chapter 4. “Hardware”.
The following sections give a brief functional description of these modules.
FIGURE 2-14:
2.2.1
The starter kit has a triaxial analog accelerometer. The three (X, Y and Z) acceleration
outputs are captured using the ADC module on the PIC24H MCU device. The
ADC-captured accelerometer samples are processed differently in the PIC24H MCU
based on the game chosen.
2.2.2
The starter kit has a 128 x 64 OLED display. Different screens are displayed for the user
to choose from. Depending on the stimulus obtained from the accelerometer and the
switches, different screens are displayed, signals are graphed and games are
controlled.
2.2.3
The speaker plays messages. The speech messages are compressed using the G.711
A-law and are stored in the program memory of the PIC24H. The PIC24H decodes the
compressed data and generates PWM signals which are demodulated before being
output through the speaker.
