Video Out of GBZ on Kite's Board

[kite]

Can you show a picture how you have it wired?

You should expect to see a still black image, not that!

Once you have a still black image, I'll point you at the cloner

Have you got another Pi that you can make sure composite video works on to confirm?

Sure thing!

Color gradient is
grey -> black -> "white" Audio L
purple -> red -> "red" Audio R
blue -> red -> ground
green -> black -> video

I know it looks a little bit strange, but it didn't have any other colors. I wanted to make it pluggable.

Plug

Sound works when I plug it in completely, but then comes the humming and the funny picture (green bar/stripes).
I've checked the contact on every cable.

I have another pi zero and pi 3 where I can check.

Looks like I have mixed up + and -

here it said: "The hole on the left, nearest to the TV text, is the signal (+) line, the pin to the right of it is the ground (-) line. Solder two wires to these pads and connect them to an RCA Jack like this one"
My TV text is on the right.

When I swap it I am the opinion I didn't have sound. I'll try that again.

The one closest to the inductor/edge of board is GND

Swap those over and then see what you get on video out. When done you should be able to do this:

Code: Select all

wget https://github.com/geebles/Circuit-Sword/blob/master/dpi-cloner/dpi-cloner
chmod +x dpi-cloner
./dpi-cloner

running "./dpi-cloner &" will let it run in the background

EDIT: I could get a plain RCA cable and solder directly without using your jack for the time being, just to prove you have video out properly.. then link up to the jack and using a multimeter to make sure you are using the right pins

[starmagoo]

I got it right!

First Test.

Test with AV Jack

Shell Scripts

There is a error in your URL. "blob" musst be "raw"

github.com/geebles/Circuit-Sword/raw/master/dpi-cloner/dpi-cloner
the alternative is to clone it via GIT

I have configured it to switch it on and off via 2 shell scripts in the ports menu.

Thanks for your help.

....

I see what you did there. And I like it.

#define MODEL MODEL_CSORIGINAL
//#define MODEL MODEL_CSADVANCE
//#define MODEL MODEL_CSPOCKET

When will you release the "pocket" version of your sword?

[kite]

Woohoo congrats good work glad it worked as you wanted!

Only thing to note is the cloner uses about 1% cpu when running, if I changed it to 30fps cloning (rather than 60fps atm) it might use 0.5% but I might change it to have command line options in future

Haha whoops I was meant to remove that from the source technically I have a fully working version already, but the LCD is out of production.. I've found a replacement but I need to make an FPC adapter in order to use it!

Ok good to know, I'm gonna check this out. Let me know when you implement it.
