Hi, I have an LCD 16x2 display and I just found out that I only can make up to 8 characters. Actually I need 16 characters and I wonder wheter there are any tricks.
I use the standard LiquidCrystal library of Arduino.
Any tricks??? Would be great

Do you need all 8 characters at a time? Only trick is you can discard unused ones and create new.

There are only 32 spaces on the 16*2 display and you want 16 custom characters. that sounds a lot to me;)
Can you describe to me what you want to do on the screen and how the custom characters will be used?

Hi,
I would like to create 2 Bar Charts below each other (for 2 x 8  sensors at the same time)
The thing is the most logical is to have them in a mirror view that's why I need 16 characters

good design! Like this one only vertically?



You can use space (or character 254) and character 255 for full and empty to save 2 characters. Then use less accuracy, 2 lines, 4 lines, and 6 lines for up, same thing for down. Then you will have two custom char left to do say 1 line up and 1 line down.
