PICDEM LCD 2 演示板展示了Microchip 28, 40, 64 和80-pin LCD Flash PIC 微控制器的主要性能。It is populated with the PIC18F87J90. 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:● VoltmeterA/D module measures the voltage of the on board potentiometer and displays a voltage between 0.00V and 3.30V on the LCD.● ThermometerThe A/D module measures the voltage of the thermistor and converts to temperature both in Celsius and Fahrenheit to continuously display the temperature.● ClockTimer/Clock function shows hours:minutes:seconds with a moving second hand using on board 32 kHz watch crystal.● Charge Pump and Software ContrastWhen using the PIC18F87J90 family of devices the LCD module can be configured as a charge pump and software contrast control is activated.
