Serial Communication
Most cameras have a manufacturer-defined serial command set for camera control and status. To utilize this capability,
EDT boards implement serial transmit and receive using standard serial lines as defined by the Camera Link standard.
You can use serial communication in a number of ways, as discussed below.
At Initialization
, the initialization process uses directives in a configuration file to set the board
registers and the driver variables to match your camera model and your operating mode. Additional directives
(especially
serial_baud, serial_init, serial_binit,
and other
serial_*
directives) can be used to
send serial commands when the system is initialized. These are described in the EDT Camera Configuration Guide (see
EDT provides several example configuration files that contain the serial commands needed to put a camera into the
desired mode. You can edit these commands or copy them to a new configuration file.
For suggestions, see comments in the example configuration files
camera_config/generic
X
cl.cfg
(where
X
is
replaced by a specific bits-per-pixel value
–
for example,
generic8cl.cfg
) in the EDT installation package.
From Command Line
The command-line utility
serial_cmd,
allows you to send serial commands to
a camera and receive its response, in either ASCII or hexadecimal format. Command-line help also can be accessed
by entering
serial_cmd --help.
If you wish to incorporate this functionality in your own application, see the source code provided in
serial_cmd.c
in the EDT installation package.
From EDT GUI
In
vlviewer
, from the
Camera
menu, select
Programming
. The resulting dialog allows you to send and receive serial
commands from the camera. For details, see
