Fixes #2: Piwebcam: Enable overriding of camera settings
How to override camera settings:
Connect to the ttyACM device and issue
/usr/bin/v4l2-ctl -L | less
Then, put the SD card back into the computer,
create a file called camera.txt in /boot and put all parameters
you want to be overridden, for example:
auto_exposure_bias=15
You can also remount the boot partition read/write to edit it
on-line:
mount -o remount,rw /boot
Now with more debugging!!!
