"display power on" doesn't work

  • Hi all,
    I have the problem that the display is losing its contrast value, after turning the display controller off and back on. I tried in several ways:


    1. with ndcucfg.exe: display power off -> on
    2. With the power saving feature of windows
    3. programatically by using the function ExtEscape()


    The display controller turns off and back on again, but then with no picture. By changing the contrast manually (e.g. "contrast +" in ndcucfg.exe) the picture reappears. Is it an issue with my lcd (ER057)?


    Thanks in advance,
    Mate

  • Hello,


    This is a bug in the display driver. I have fixed it today.

  • Hi Holger,
    it seems to work. I have tested it with your demo app (nd52_video_power) and the display gets black and reappears after 5 seconds. Is there any chance to get that error fixed in the cf2 image - our boards are currently preinstalled with NK82_CF2_061024?


    Thanks,
    Mate
