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. :lol:

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 -

https://learn.adafruit.com/introducing- ... eo-outputs
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

I got it right! :D
SpoilerShow
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?

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. ;)
