Hello,
First, i want to apologize for my bad english.
I am no developer neither hardware nor software, all i do is tinkering around with some arduino stuff.
My Headunit features RGB backlit buttons on the front panel.
I would like to have everything in my car RGB which isnt the problem since its only replacing the stock bulbs with rgb leds.
To controll them i want to use an adruino pro mini which is controlled by the headunit. and there is the problem.
The RGB setting is handled by android and given to the mcu which handles the led controlling (i guess)
So the best solution would be to somehow let the arduino read from the bus between the two and that way let it know the values for RGB.
My crude solution is to simply add 3 optocouplers (1 for each channel) and get the infomation that way.
What do you think?

First off, grovelling apologies for what is probably a painfully newbie-ish question - I am entirely new to Android phones. I have tried searching - came across this thread, for example: http://forum.xda-developers.com/showthread.php?t=1124669 - but haven't found much in the way of practical solutions yet. This may conceivably be more of an "Android question" than a "Galaxy S2 question" as well, I'm not sure....
Anyway: one of things I use my phone for an awful lot is watching videos. What I'd like to be able to do is get the the display a little closer to a properly callibrated TV - so the whitepoint should be somewhere near D65, proper white balance across the whole grey-scale, the gamma somewhere near 2.2 across the scale, primary colours not too saturated, and so on.
The main problems at the moment seem to be that the white point is pushed quite badly towards the blue, and that the green primary colour is oversaturated (this is in line with the findings in the thread above). So my question is: what can one do about this?
I've investigated the "Display" settings menu, and discovered the "auto-adjust screen power" option which (again, according to the thread above) improves the gamma (reducing black-crush) at the cost of somewhat reducing maximum brightness. I've also spotted the "background effect" option; setting this to "Movie" makes colours a bit less over-saturated, but green saturation still isn't right. And within the standard video-playing application I've got the "colour balance" set to "Warm", which helps with the blue push a little, but not enough.
Are there any other display adjustment/callibration options that I've missed? Are there any apps which allow the display characteristics to be tweaked? And are there any 3rd-party video-playing apps which allow more precise callibration of the overall colour balance without compromising playback performance?
Hi Everyone..
Is there any way or an app by which we can adjust not only the Brightness and contrast, but also saturation, gamma correction and adjust the color balance of the TFP screen?
I browsed a bit but could not find any!
Thanks!
I don't think there's any app out like that. It may be possible after rooting. I think Asus doesn't allow that because most wouldn't really know what their doing and mess the whole display up..lol.
If i come across something like that ill let you know.
I am connecting my Nexus 4 to a projector - but the resulting image is trapezoidal due to keystone. I want to be able to control this using software such that the image that goes out of the android is already corrected for this problem (In such a case, the projection will get smaller for the wider edge of the trapezoid and will be equal to the narrow edge; the remaining area can be black pixels.) There are two things to do here - one is the actual algorithm for keystone correction, which I think I have found here - Algorithm for software keystone correction. Any other efficient algos? And the second is how to modify the displayed screen in android to the one I want to send (if I were somehow able to change the android screen resolution to a trapezoidal value!). I don't mind distorting the phone display as long as the projected display is good. Also, would prefer this for any running app, not necessarily my app. Thanks a ton!
Hi everybody
Have you tried the item can used as led lamp also paly music with color changing? I want to find this lamp can support bluetooth distance at least 30M, I found some only support 15M, then the bluetooth disconnected. If I have a big house, I should control the lamp in the baby room while I am in another bedroom. any one can give some suggestion? thank you.
Hi all,
Have been investigating some sources of eye strain and headaches with the PIxel 6, none of the PWM apps work for me, but it's been suggested that temporal dithering employed by the device might be at least a part of the problem.
Does anyone know if it's possible to turn this off in software? if rooted possibly?
It certainly seems that some older ROM toolkits had the ability, but they've long gone.
T.I.A.

I would like to see some solution for Pixel's 6 PWM as well.
I have also tried multiple apps. They help a little, but the issue with Pixel 6 is that it flickers even on 100% brightness.
I do wonder if it it even remotely possible to force the device to DC dimming or there are HW barriers.
