I would like to build PCB that would have 3 major functions:
1.) it would drive 5 inch LCD display. Video source would be HDMI signal. LCD model is "[url removed, login to view]"
2.) it would extract/split audio signal from HDMI, so i get line out stereo signal ([url removed, login to view] audio jack)
3.) this LCD also has 4 wire resistive touch screen integrated (4 wires are integrated into LCD FPC). So i would like this PCB also to implement touch screen controller. Please use some cheap touch screen controller chip. Touch screen would be than sent over USB to PC.
Why i need this PCB?
The idea is to connect this pcb to mini Android computer - MK802. ([url removed, login to view])
MK802 has theese interfaces: HDMI1, USB-HOST, USB OTG.
So i would like to get video signal on 5 inch LCD, i would like to get audio signal from HDMI signal and i would like to control MK802 with touch screen over USB.
I would like developer to:
- provide schematic, firmware, PCB(gerber) so i can manufacture this pcb myself
I would like some cheapest components (controllers) to be used. Please as you progress inform me which components will be used.
Please ONLY bid developers who have done something simmilar before (HDMI controller, touch screen controller,..), because I will assign this project only to bidders who has done something simmilar before.
