Use this function to set the brightness of lcds backlight. This function only takes affect if the backlight is in "on" state ( %LCD.LightControl(1) ) and the lcd driver supports this feature.

The function demands the brightness (0..255) as the only parameter. 0..255 means that 0 = darkest value and 255 = brightest value.

Example:

%LCDs.Brightness(128)
