Hello everybody,

I'm looking for a way to refresh a part of the display without erasing all with glcd_clear(). Because clear() is very very slow (like 2s) and I need to update data quickly... If I try to redraw data at the same position without clearing the screen, the characters get stacked one over another and it's giving me ugly symbols.
Isn't there a function to erase just a line or just a character so I can clear the old characters before drawing the new ones while keeping a decent refreshing rate.

Thanks in advance for your help !

Hello Pierre,

Are you using Flowcode? If so then please can you sign up to the Flowcode forum using the links in my signature.

Using the print function with transparency set to 0 should allow you to correctly overwrite old text with new text.
