Universal Status Reporting module

by Stu
(Spencerport, NY)

Universal microcontroler and LCD display

I would like to be able to use a microcontroller with an LCD display as a stand alone unit that I could incorporate into my circuits.

I need to be able to display either error codes or voltages etc. Such as:

If an input is pulled high or low The display may say "System on" or if a voltage on a line is 12.65 volts, the display may read "Fuel Cell Voltage = 12.65" etc. etc.

I would like the unit to be universal. I wire it into a circuit and change the display text.

This is probably too long winded and rambling but I hope I got the idea across.

 Serial LCD
by: Justin

You can always get an LCD and use it in 4 bit mode but that takes seven pins and a lot of wiring to move from circuit to circuit.

I just ordered a serial LCD controller that uses USART to send the text to be displayed. eg. if "Hello" is sent then "Hello" will appear at the current cursor position.

(I ordered the LCD from an ebay store).





Good luck,
Justin
