LCD for 2 proyects - Electronic Circuits Projects Diagrams Free

Happy New Year to everybody here. I have a problem: I wanna use one single LCD (16*1) for 2 diferent proyects (frecuency meter and LCmeter). I will use one and later the other. In other words, i will not use the both circuits at the same time, one first and the other later

hi,
How are you driving the LCD.? PIC etc?
If you are writing your MCU programs, you could program the MCU to be either a Fmeter or LCmeter..

It would be useful if you could post a simple block diagram on how the two meters and the LCD are required to be connected..

I'm drivind the LCD with a pic,but dont do the code

Here are the schematics of both meter

hi,
Only one, the LC, schematic is shown..

Is this right?
On the web you have found 2 meters that you want to build.
You only have 1 LCD display you would like the circuits to share it.
You do not know how to program in any language.

Just put the LCD display on a header, your PCB then uses a socket and you can plug it into either.

Why not just buy another one. It's not like they're expensive.

In my country, they're very expensive, like 27 $USD. That's the reason that i wanna do this proyet

Take a look at the mondo superprobe.

It uses a 7 seg LED display and has 17 functions including freq and cap meter.

I'll ask the fellow at Mondo if he minds me making the superprobe a kit.

I'd really like to bring it up to date first. And add the debug port, 16F886 or 18Fxxxx ?

anthony123 · 8th January 2008, 01:11 AM

mmmm that's a really good option, but the range are not that i'm looking for..

The super probe could use a LCD display.

The unit is designed to have as many functions possible using as few parts as possible. It works surprisingly well. A little TLC and a handful of parts might result in an improved tool. The voltmeter function is limited to +5. A nice autorange voltmeter without that limitation would be nice.

But i need to use one single LCD to 2 proyects
