Posted on November 01, 2013 at 22:49Screen now is +- working. And contrast is superb, 1:10k. LCD can't do that. and viewing angle is >80 in all directions
(Hrr, fun does not end here, i have no blue color, have no idea why. I tested AMOLED and it is working with phone as it should. Ideas ? )
http://www.youtube.com/watch?v=-HWi4mpZ_PE if i want speed i can overclock, nearly double original speed, and if i want even more speed i have ADSP-21489 for it. And even if that would be slow, i always can take arm cortext A9 running 1.2GHz ( TI Sitara )
My goal is to get it working, so i can use it for project as it is, or use integrated controller like S1D13517.
I give up. I extracted init values while probing phone, i set LTDC controller so it generates same timings as my phone. and yet, i have problems upon problems. My biggest that i don't have one of three colors, now i don't have RED color,even if i connect all RGB565 line to VCC ( i should get white, but no, i get cyan).
Even when timings are the same, i have small line for x and y coordinates. Now only thing that's left is AMOLED voltage that is different. Phone use 2.8V for internal circuitry, but i use 3.3 ( max is 3.6V, so i should be ok ) VSS is exactly the same since i have DC/DC converter for it. and power-up is controlled by AMOLED controller, and it's working)
I don't know what can i do more. I only need to get it working, speed is not a problem for testing
