Made some progress last night: https://image.ibb.co/iHVzpm/HDMI_Board_Vineheart01.png Atm I think the mysterious chip has to be a companion of the touch controller and is useless for us.

That one took me about 5mins to even make out a single digit lol, not even sure if i read it right. Knowing our luck, that bottom right one is the backlight con...

I saw that particular piece of code and I also had the same doubt! in the first place why is he initializing it with arduino? the scr...

I think you have a power supply issue. The PowerBoost is rated at 1A max. If the Raspi and the other components (display, controller9 use too much power (current), the voltage will drop, then the components become unstable or crash. I saw that some builds with the Pi3 use a super cap to stabilize th...
