OSContrastValue Variable (Macro)

system.h

unsigned char OSContrastValue;

Byte containing the value of the current contrast.

Note that if you change this byte (valid values are 0-15 on HW1 and 0-31 on HW2), the contrast will not be changed. You have to use OSContrastUp and OSContrastDn to actually change the contrast.
