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,
