how many lcd pages can you make?
Thanks

#2

Someone can correct me if I’m somehow wrong, but I don’t think there’s theoretically any limit. You tell the code, “If this button is pressed, add 1 to the page number.” And then the page number corresponds to text on screen. I don’t know what language you’re using, but this is the basic idea. I’ve used an LCD screen for autonomous selection, and I had 8 or so pages I believe… Page number is just a variable that can be used to tell the screen what it should display.

thank you

As many as will fit into memory, which means more than you will have time to scroll through during a match.

it is still not working

#6

what should i do?

#7

Someone hasn’t played No Man’s Sky…

#8

What doesn’t work. Also try reposting the code with the code tags ( button that looks like </>)
