Hi all
I have configured the DCUL7 with 256 color palette and TFT display.
How to change the contrast or brightness value in the DCUL7?
Thanks.

A TFT display has no contrast voltage as it is required for STN and CSTN displays. But depending on the display and inverter, you can sometimes change the backlight brightness of the TFT display. As the DCUL7 can drive both, TFT and STN displays, it is equipped with a STN contrast voltage circuit. This voltage can be regulated with the software and can also be switched on and off. This can also be used to control the backlight brightness. However you'll need some additional hardware to make this voltage (0..35V, Vee- or Vee+ on the display connector) work with your specific display.
