11.11 Set Increment/Decrement of the contrast set (D6/D7 H)
This command can increase the contrast step by +1 (D6 H) and decrease the contrast step by –1 (D7 H).
It is the most convenient way to change the contrast of the display by programming.
11.12 Set Normal/Inverse Display (A6/A7 H)
This command turns the display to be either normal (A6 H) or inverse (A7). In normal display mode, a RAM data of 1
indicates an illumination on the corresponding pixel in the normal white panel. In inverse display mode, a RAM data
of 0 will turn on the pixel. It should be noted that the icon line is not affected. The icon line is not inversed by this
command.
Example:
For a normal white display panel (Set Normal Display: A6Hex):
