Chapter 3. Tutorial

The tutorial program is preprogrammed into the sample device. (For example, the file p16demo.hex is for a PIC16 device and p18demo.hex is for a PIC18 device.) This program also is on the included CD-ROM program disk for user reference. (If the sample device has been reprogrammed with another program, the tutorial may be reprogrammed into the device.)

For a flowchart of the tutorial program, see Figure 3-1.

For detailed information on the PICDEM 2 Plus hardware, please refer to Appendix A.

3.1 TUTORIAL PROGRAM OPERATION

The tutorial program is made up of four components, which are individually displayed on the LCD.

1. Voltmeter

This mode uses the A/D module to measure the voltage of the R16 pot and display a voltage between 0.00V and 5.00V on the LCD.

Voltage is continually updated until the mode is exited by pressing RB0.

2. Buzzer

This mode turns on the Piezo buzzer, using the CCP1 module I/O pin, RC2.

The period and duty cycle of the CCP1 frequency can be changed while the buzzer is on. The changes in period and duty cycle are recognized immediately in the buzzer tone.

- To change the period and/or the duty cycle, press RB0 under the “Buzzer” menu.

The buzzer will then sound off with the default setting of 80h for the period and duty cycle. The cursor will flash over the period’s first digit, indicating that the PR2 register is ready to be incremented.

- To change the duty cycle, press RA4 once and the cursor will now flash over the duty cycle’s first digit, indicating it is now ready to increment the CCPR1L register.

The next press of RA4 will exit the buzzer function.

3. Temperature

This mode uses a TC74 thermal sensor to measure ambient temperature in Celsius and then display that temperature on the LCD. Communication between the PIC is exited by pressing RB0. This mode contains code that will write to the external on-board EEPROM. Every two seconds, the code will write to a defined EEPROM address and store the current temperature in that address.

MCU and sensor is accomplished using the MSSP module. This mode

PICDEM™ 2 Plus User’s Guide

4. Clock

Once this mode is entered from the main menu, a Real-Time Clock will start counting from 00:00:00.

The Timer1 module and a 32 kHz clock crystal are used to establish a Real-Time Clock.

By pressing RA4, the clock time can be set to the user’s preference. When RA4 is pressed to set the time, the cursor will flash over the hours’ ten digit. Press RA4 again and the cursor will now flash over the minutes’ ten digit.

RB0 is used to increment hours and minutes whenever the cursor is flashing over either. After the minutes have been set, press RA4 and the time will be set and the LCD is returned to an active clock display.

The data that is sent to the LCD is also sent to the RS-232 serial port using the USART on the PIC MCU. A HyperTerminal™ program on the PC will be able to display the same information that is displayed on the LCD
