Old Text Does Not Clear

How do I fix this overlap of text, it seems it does not always clear the old text out when the mode changes.

You have to use the ReefAngel.LCD.Clear function. You have it in your code already. Just make sure you do it in the area where the text is overlapping before you draw your mode.

You need to clear anything you want to erase.
You already have something that clears in your code. I just don't know what it clears.
You must do the same thing for the area of concern.

Code: Select all

ReefAngel.LCD.Clear(COLOR_BLACK, 1, 11, 132, 11);

ReefAngel.LCD.Clear(COLOR_BLACK, 1, 11, 132, 11);

Those gave me the horizontal black lines. Did I use it incorrectly? How do I use it to clear?

Use color white and expand the coordinates to go over the text in concern
