This project will show you how to drive a 16x2 alphanumeric Liquid Crystal Display (LCD) using a PC.
First we show how to connect it to the parallel port and echo and handle keyboard input.
Then we show you how to use the LCD to display temperature using the included Dallas DS1620 Digital Thermometer / Thermostat chip and set the HI & LO trigger points in it. Once the DS1620 is programmed it may be removed and placed in another device for temperature control.
