I was messing around with my 16x2 LCD display yesterday, and I discovered that there's no truly easy way of scrolling only one line of text while leaving the other stationary. A quick google search proved frustratingly fruitless! A few people in the past have had similar questions, and the answers t…

Thanks a lot for this. As a beginner, I've been trying to wrap my head around one line scrolling and this is the best solution I've found so far. But the 39 character limit is a bummer. Have you been able to improve the code to include more than 39 characters? My first thought was, can't we use subs…

I managed to write a code to solve the problem. It works, but almost certainly it isn't the best way to do it. I would love to have suggestions, improvements and corrections! // Code for printing out a fixed string in line one of 16x02 LCD, and a scrolling // string with unlimited length in line t…

If you wanted to avoid using a ram buffer you could use my hd44780 library (hd44780_pinIO class). It can read the display ram so you could read & write what is on the display to actually move the characters location in display ram. You would also need to hook up an extra Arduino pin for the r/w li…
