Topic: Clear a specific line (Read 1 time) previous topic - next topic


i need help to clear a specific line on arduino uno , with the LCD SPARKFUN 128x64 .



What does the data sheet say?  Got a link?



I assume by "a line" you mean a line of pixels and not a line of characters. Did you try drawing a horizontal line from the left side to the right side?

sparkfun sells multiple 128x64 glcd products.

If you have the serial backpack version see the datasheet.
The datasheet shows a erase block command which allows you to specify
x1,y1 and x2,y2 coordinates for the block erase.

If using the non serial based product, you will have see documentation for whatever library
you are using to control it.
