This project will show you how to show how to use a 16x2 alphanumeric Liquid Crystal Display (LCD) with a PC. First we show how to connect it to the parallel port and echo and handle keyboard input.
Then we show how to use the LCD to display temperature from a 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.
All C source code is provided for you to learn from along with many web references.Specifications
