Hi Lonkny,
Unfortunately, I don't believe LCDC has specific support to dynamically change the backlight colour of our tricolour displays yet. You can check in at lcdc.cc to see what they're up to, maybe post a request in their forums, and even send an email directly to the LCDC creator, Matt, while you're there.
You can, however, save your desired start-up backlight colour. If you set remember on, save the base backlight colour, and turn remember off you should see your colour on startup. You'll need to send some basic commands to the display, so I'd recommend taking a look at the
manual, and downloading our
uProject software.
In uProject, set up your communication settings, then move over to the main tab and test them out with the backlight check box or the send text button. If communication is good move over to the uploader tab, open up the other branch and drag a raw data command into the window. Again, be sure to confirm with the manual but I believe you'll need three commands; 254 147 1, 254 130 [red] [green] [blue], and 254 147 0. Once these are entered, hit execute or F9, double check your communication settings, then hit ok to run. When you're done, you can save this command list for another time.
If you have any further questions or concerns regarding your LK204-7T-1U, don't hesitate to post.
Thanks,
~Troy
