Hi all!

Maybe something wich can be used.

Perhaps another way to make a voltmeter on. 0 - 30 Volt with 1or 2 digits after the decimal.

First, I must admit the calculation I have used from a sample of seven segment led displays from MM. My idea was that it could possibly be used for a LCD diplay too. At some changes here are a functioning voltmeter. Of course you need to make a voltage divider using resistors as always. I have tested it, and it work fine.

Hi Jorgen!
Thank you for sharing that with us!
I alter your flowchart and I made an simple voltmeter with some custom 7 segment display. It`s awesome
I attach the new flowchart and a photo with the voltmeter.

Hi Bercioiu!

Wery nice, In fact, it was the original with 7seg I changed to lcd, hi hi.

Thank you for sharing, I will test your program. I am pleased also to contribute.

I noticed that was originally with that type of display because I saw the name of the variables.
The flowchart is a little spread due to the type of display that I used. I forgot to translate in flowchart, "AFISAJ" stand for ANODE, and "CIFRA" for displayed digit. The last switch case is for the uniform brightness of the three display.
Enjoy!
