The PICDEM LCD 2 Demonstration Board (DM163030) shows the main features of Microchip’s 28, 40, 64 and 80-pin LCD Flash PIC microcontrollers including the LCD voltage booster and contrast controller. It is populated with the PIC18F85J90. Other devices are supported via a transition socket and are available separately. A sample LCD glass display is included for custom prototyping. The glass features 7-segment displays, wipers, thermometers, star bursts, and other common icons.
Included applications: ● Voltmeter A/D module measures the voltage of the on board potentiometer and displays a voltage between 0.00V and 3.30V on the LCD. ● Thermometer The A/D module measures the voltage of the thermistor and converts to temperature both in Celsius and Fahrenheit to continuously display the temperature. ● Clock Timer/Clock function shows hours:minutes:seconds with a moving second hand using on board 32 kHz watch crystal. ● Charge Pump and Software Contrast When using the PIC18F85J90 family of devices the LCD module can be configured as a charge pump and software contrast control is activated.
