Hello, i would like to ask a few questions about whether i could find somewhere some examples of how could i print serial monitor inputs longer than the 16 characters limit of a 16x2 display. I've tried so far the basic example that comes with the arduino IDE but i can't seem to wrap my head around…

[image] cateaua96: for (lcd.scrollDisplayLeft()=0, lcd.scrollDisplayLeft() < 128, lcd.scrollDisplayLeft()++) } That is not how to use the function. Call the function before each print . That will shift the whole display one character to the left or right. Then print to the new blank sp…

Please take a look on the code i pasted in the post before yours, am i doing it correctly? That's what i'm trying to do for a while, but i'm really noob.

[image] groundFungus: Count characters and if more than 16, scroll and print the next character. Well from your first description I thought that these details are all managed by the library. handover 200 characters to the library and the library starts scolling the 200 characters through the…

[image] StefanL38: handover 200 characters to the library and the library starts scolling the 200 characters through the display automatically without any additional line of code. This page covers the memory organization of the hd44780 controller and shows why scrolling is necessary to displ…

[image] StefanL38: handover 200 characters to the library and the library starts I thought the library would have some function that does the scrolling "in the background"

[image] StefanL38: I thought the library would have some function that does the scrolling "in the background" Sorry, I misunderstood. The hd44780 library has no function like that that I know of. There is line wrap, but that goes to the next line, not continue on the current line.
