Programming 363

Programming Model 363 Cameras/camera modules

This article reflects the current state of the software to operate Elphel model 363 camera, including synchronizing of multiple camera. Not all the software is in the final state, but - anyway.

Sensor board control (10347)

CCD sensor front end in the model 363 camera consists of a sandwich of the two PCBs - 10347 - FPGA-based timing/interface module and 10342 - analog sensor front end. In addition to the 10342 board, 10347 controls optional mechanical shutters, it has interface connectors fro some 35-mm motorized lenses, opto-isloated I/O for synchronization and general purpose 5VDC output that can be used to turn on fan or drive other circuitry.

This board is controlled from the processor board ([10353]) through a 2-wire serial interface, there is init347.php (can be reached as http://<camera_ip>:81/init347.php) that sets initial values to the sensor registers (commented in the code), including main and mechanical shutter sequencers. This script is called automatically during camera initialization, it can be used as a sample for custom PHP applications to control the acquisition parameters, for manual changing parameters I would recommend copying it (or modified version) to RAM-disk based TMPFS (ftp to /var/html directory in the camera) - it will be availble as http://<camera_ip>:81/var/init347.php (or you may rename it as you wish, preserving .php extention)
