Dummy needs LCD tutorial,

[DynamoBen]

I'm working on a project right now that is displaying a similar LCD display. I have a bargraph for the bottom of the display and text values for the top.

I used the following basic stamp project as a template to start from.

With PBP you don't have to mess around with all the nibbles that are in this problem. Also you will need to alter some of the variables. In the end I stripped out all the subroutines that write to the display and just used LCDout. Works great! It took a little bit to understand some of the math but once you have that it makes compelete sense and works well.

Hi all,

And thanks for all the infos. Now i've understood most problems and i can display almost all what i want and it will be enough for my project.
I have to measure currents and voltages that are moving rapidly, they follow the voice shape.
I used the code sent here in this post by Acetronics. I removed all what i did not need and it works perfectly.

As the display is moving fast, it would be nice if i could display a "holding bar" for a few moments at the peak value.

What is the best way to store the peak value in a variable ?
Maybe somebody has already made a similar code ?

For the moment i did not use an analog input, i randomly generate the values.

Greetings,
