3.17 Generating Test Patterns

The camera can generate a test pattern to aid in system debugging. Use the command
svm 2
at 0 again. Use the test pattern to verify the proper timing and connections between the
camera and the frame grabber.
End-of-line Sequence
To further aid debugging, the camera can generate an end-of-line sequence. The end-of-
line-sequence outputs "aa", "55", "aa", "line counter", "line average", "pixels above
threshold", "pixels below threshold", "derivative line sum". To activate the end-of-line
sequence, use the command
command
