How to change the resolution of an lcd screen in the text-lcd-16x2 code


I have a 20x4 screen, but it looks like there is no code for that, so, how can change the code so it fits the screen?


I don’t have a 20x4 LCD on hand to test this with, but can you try with the node available from importing the attached “xodball” and see if that works for you?

You can also try if your LCD has an I2C interface, which it doesn’t look like it does… I only have a 16x2 screen to test on, so it would be nice to have someone verify it does work for other sizes.
