video output through gpio
#1
I use a pi3 in an arcade i built and currently get video to my tv via component output with a 240p signal using a retrotink... 

i was curious since the tinkerboard has gpio as well is it possible to get something like the retrotink working? It uses the gpio to output component ypbpr..

curious if anyone has ideas or insights. http://retrotink.com

Hi, sportman
   Thanks for your information sharing. I just read the website. Since the author did not open source for this project (he just provide the lakka/retropi image link which modified by him), we have no enough information to check if Tinker Board can support or not. Need the author give more info to us.

New version 2.0.3 is out for download.  May have fix for some problems.

Is this the interface being used by the retrotink?

The first was the gert VGA ( https://github.com/fenlogic/vga666 ) which I think these are a refinement of.

documents/vga_manual:
Quote:the BCM2835 has a parallel display interface on the GPIO pins .. The B+ however has all of the necessary DPI signals brought out.

I've not seen any mention of the rockchip rk3288 having similar features so it's probably not easily possible.

We did not see the related SPEC. from RK3288 also We are checking with our chipset vendor now.

RK3288 can support DSI interface but needs to use the dedicated pin and these pins can not use as GPIO.
In other words, Tinker can not support DSI through 40 pin GPIO header.
