Adjust the Cropping

This is now deprecated in the latest firmware release

The original purpose of the cropping was to avoid compatibility issues. The latest firmware has found a fix for most of the problems and now the full area should be usable without need for cropping.

The instructions below are retained for legacy users who have not updated.

The NeTV2 crops the overlay image by 32 pixels on each side horizontally and 10 pixels vertically. This is done to avoid any problems with compatibility with some TVs that are very fussy about data being modified near the edges of the screen.

You can try to open up the cropping for your particular system by doing the following set of commands:

ssh [email protected]  # assumes you have bonjour installed, see guides on finding Raspberry Pi IP address otherwise

pm2 stop netv2-status  # this prevents the netv2-status daemon from "stealing" flterm characters
cd ~/code/flterm
./flterm --port /dev/ttyS0 --speed 115200  # this opens a new terminal session to the NeTV2 command line interface
# now inside flterm
debug setrect <left> <right> <top> <bottom>  # items in <brackets> should be an integer that is the pixel offset desired
# hit control-c to break out of flterm
pm2 start netv2-status  # restarts the status reporting daemon
