Cf-533

I have a CFA-533-YYH-KU. It installed 633_Wintest.The backlight works but the LCD Display does not.
Also cf_linux_examples for 633 seem to have the same effect.I have tried quite a few commands.The write to LCD , Contrast and Keypad Activity don't seem to work.
Is there a special 533_wintest or equivalent?
Looking for additional LCD resources? Check out our LCD blog for the latest developments in LCD technology.

The CFA633 version of WinTest should see the CFA533 and communicate with it without any issues.

Does Windows see the CFA533? Is there a virtual Com port set up for it in Device Manager? You will need to select this port in the 633_WinTest for it to communicate. Once you do, you can also toggle between the two baud rates to see if that works as well.

Yes Windows can see CFA 533.I can also see it in the Device Manager.And I can only change the brightness of the LCD using 633_Wintest.No other command seems to work.
