<p>This is a collection of tools for the 8.0 software development/testing, you can provide parameters in HTTP GET request.</p>
<p>Here are some of the current options</p>
<ul>
<li><a href="?constants">constants</a> - list all defined PHP constants related to Elphel camera</li>
<li><a href="?profile=50">profile=50</a> - show last 50 (up to ELPHEL_CONST_PASTPARS_SAVE_ENTRIES=2048) profile entries - recorded if profiling is enabled</li>
<li><a href="?histogram_direct=0.5">histogram_direct=0.5</a> - show part of the pixels below specified output value (on 0..1.0 scale - 0.5 in this example) for each color channel </li>
<li><a href="?histogram_reverse=0.5">histogram_reverse=0.5</a> - show pixel output value (on 0..1.0 scale) so that specified part of all pixels have output (after gamma conversion) valuebelow it, for each color channel </li>
<li><a href="?gamma_direct=0.5">gamma_direct=0.5</a> - show output pixel value (on 0..1.0 scale) for the specified (0..1.0 scale) sensor pixel value, for each color channel </li>
<li><a href="?gamma_reverse=0.5">gamma_reverse=0.5</a> - show what sensor pixel value would produce specified output (after gamma conversion) value (on 0..1.0 scale), for each color channel </li>
<li><a href="?jpegheader">jpegheader</a> - show data in the current JPEG header</li>
<li><a href="?frame=0">frame=0</a> - show raw data for the frame parameters internal data. There are 8 parameter pages used in sequence, so only the 3 least significant bits of the frame number are used</li>
<li><a href="?histogram=prev">histogram=prev</a> - Show histogram data for the specified frame - in addition to the absolute frame number you may specify prev1...prev6. Giving future or too long ago frame will result in an (uncaught) error</li>
<li><a href="?hist_raw=prev">hist_raw=prev</a> - Show raw histogram data for the specified frame - in addition to the absolute frame number you may specify prev1...prev6. Giving future or too long ago frame will result in an (uncaught) error. It shows the same data as <a href="?histogram=prev">histogram=prev</a> - just uses different access to the histogram arrays.</li>
<li><a href="?gamma">gamma</a> - show structure of the gamma tables cache. Among othe data it provides links to the individual gamma tables pages. This command takes morfe than 10 seconds to complete.</li>
<li><a href="?gamma_page=255">gamma_page=255</a> - contents of the gamma tables cache page (0 - index page, 1..255 - cache pages). Individual pages links are provided by the <a href="?gamma">?gamma</a> command. Some of the tables in the cache (reverse, FPGA) may be missing if they were never requested.</li>
</ul>
<p>There are additional development pages links available:</p>
<ul>
<li><a href="parsedit.php">parsedit.php</a> - this page includes links to multiple useful parameter controls as well as explanation how to create custom control pages by just modifying the URL line</li>
<li><a href="/tuneseq.php">tuneseq.php</a> - run-time tuning of sequencer latencies;</li>
<li><a href="$imgsrv">imgsrv</a> getting images from the camera internal buffer (you have to acquire them there first)</li>
<li><i>forced synchronization mode</i>: <a href="/fpga.php?a=0x4e&d=0x60">ON</a> and <a href="/fpga.php?a=0x4e&d=0x40">OFF</a> (default). When this mode is activated the camera will force re-synchronization between the sensor and the FPGA compressor at each frame start. Normally it is not needed and loosing synchronization is usually an indication of a software/fpga bug (there are some rare conditions when this is normal), this is why this mode is disabled by default so the problems would reveal themselves.</li>
<li><a href="/var/klog.txt">var/klog.txt</a> - read kernel messages (you first need to telnet to the camera and run "printk_mod &" and enable some of the DEBUG bits)</li>
</ul>
<h4>Make sure to run "printk_mod &" before enabling debug bits - some are from interrupt service routine, and default printk() output to console can really mess up things and make the camera "freeze".</h4>
