NAME:
|
|
Demonstration of Autoscroll function
|
|
|
|
DESCRIPTION:
|
|
This sketch demonstrates the use of the autoscroll() and noAutoscroll()
|
|
functions to make new text scroll or not.
|
|
* The sketch is intended preferrably for 16x2 LCD, but can be configured
|
|
for 20x4 LCDs just by uncommenting and commenting related sections.
|
|
* The sketch is just for demonstration purposes, so that it is not
|
|
optimized for memory usage.
