Description

• Save / restore / initialize NC393 based camera systems parameters.

Notes

• The project was ported from NC353 camera series with minor changes related to:
  • reading the extension board information
  • having 4 sensor ports instead of a single one
• The camera system type is stored in the EEPROM of the 10389 extension board and is not reset by software updates
• Depending on the initialized ports the configuration files are stored in /etc/elphel393/:

http://192.168.0.9/autocampars.php?sensor_port=0 -> /etc/elphel393/autocampars0.xml
http://192.168.0.9/autocampars.php?sensor_port=1 -> /etc/elphel393/autocampars1.xml
http://192.168.0.9/autocampars.php?sensor_port=2 -> /etc/elphel393/autocampars2.xml
http://192.168.0.9/autocampars.php?sensor_port=3 -> /etc/elphel393/autocampars3.xml

• Storing parameters is done individually per port (access and hit save 4x times).
• If the configuration for a port not found on boot but it was initialized - a new default configuration is created
• If accessed from a browser supports:
  • reboot - works for single cameras, for multi camera systems works for the master camera that is supposed to reboot others.
  • cancel sync - if the camera was booted from NAND flash - cancels syncing of the overlayfs layers if not needed - as any changes to the configuration files through the web interface raise a sync 'flag' (/tmp/overlay_sync)

Usage

Fig.1 autocampars.php web interface

web

• http://192.168.0.9/autocampars.php (Fig.1)
  • the top table gives access to change the camera/sensor parameters through parsedit.php interface. The parameters are split into groups. Select groups of interest then follow View/Edit current link.
  • the bottom table allows to save/restore the configuration of all parameters. If boot from NAND flash the changed configs must be synced to survive reboot - use either REBOOT button or shutdown -r now ('reboot -f' will not sync overlayfs layers)

command line

• only to (re)create new config

Terminal:

$ ssh root@192.168.0.9
root@elphel393:~# /usr/bin/autocampars.php

Output:

Usage: /usr/bin/autocampars.php [--init] [--new] [--ignore-revision]
Initialize camera using saved parameters (usually at boot)

Source

• elphel-apps-autocampars is integrated and built using the elphel393 project that sets up the build environment and pulls all projects.
