Increasing/Decreasing LCD Contrast
The contrast of the LCD display varies with the ambient temperature. Therefore, this terminal
automatically detects the ambient temperature and determines an optimal contrast based on the
acquired data. However, it may not immediately react to rapid temperature variations or be ideal for
each specific user. This function is used to correct the contrast value, which has been automatically
calculated by the system, to an optimal level.
The resulting contrast value adjusted using this function can be acquired via the
SYS_GetLcdContrast() function.
