testcard

Post by pa2mrx » Sat May 04, 2019 9:13 am

Hi All,

I completed one portsdown using the Limi -mini. Now my question is:
How do I change my testcard when TX-ing. I already managed to change is using "https://wiki.batc.org.uk/Portsdown_2018 ... 2_Software" This works for "comp video", but when changing back to lime-mini or portsdown again I get the girl testscreen again.
Next: where are these pictures located and called on de SD card, so i can use my own.
**Edit: ignore the location question, found it searching the directories. "/home/pi/rpidatv/video".
I use 201903250 version.

Thanks

Hi Frank

The Test Card F used for the transmit test card modes is stored at

Code: Select all

/home/pi/rpidatv/scripts/images/tcf.jpg
The image name is hard-coded in multiple places so you will need to replace it with an image of the same name (and size).

Note that any new file will get over-written by any software update, so keep a copy handy!

Dave,

thanks for the info.
I found these other also in another directory since I knew where to look for.
