LCD Usage
LCD Initialization
216
ATmega169/V
The following section describes how to use the LCD.
Prior to enabling the LCD some initialization must be preformed. The initialization pro-
cess normally consists of setting the frame rate, duty, bias and port mask. LCD contrast
is set initially, but can also be adjusted during operation.
Consider the following LCD as an example:
