rev3 first web only edition running in javascript on the device.                                                                               


rev4..5: added CLAHE contrast enhancement, noise reduction, peformance improvement, see blow.                                                                                                                                                               


====Raw Viewer for the internal Webserver (recommended)====
It is also possible to use the Raw viewer directly in the browser.


To achieve this, the stream had to be proxied from port 5000 to 80 due to CORS.


luckily the internal lighttpd had the CGI module enabled, so piping it troug (using wget ... i know) worked with very low overhead.




To install, you need '''Terminal access''' to the Camera. see below.
optional for simplicity: '''ftp''' access
[[File:Dali D8X3N Webviewer.png|thumb|Web Raw Viewer with histogram (rev3)]]
Create the files and the code inside.
'''/app/web/webpages/raw.html''' https://pastebin.com/LM3Gmeez
'''/app/web/webpages/raw.js''' https://pastebin.com/n9wAVW63
and
'''/app/web/webpages/cgi-bin/proxy.cgi'''      https://pastebin.com/vii1HXcU
then run
chmod +x /app/web/webpages/cgi-bin/proxy.cgi
'''restart''' your camera.
It should be accessible now trough '''http://<camera ip>/raw.html''' in the browser and click Start Stream
'''NOTE''': ''<u>If it does not work</u>'', check the contents of both files. FTP sometimes messes them up.
also run
dos2unix /app/web/webpages/cgi-bin/proxy.cgi
because linux <> windows difficulties that couldnt be resolved in over 30 years.

To access the Terminal you need to solder or plug in a UART connection to Connector J7 on the "Glue" board.

''See "Automatic Dead Pixels and Flatmap Correction" below how to create new dead pixel and flatmaps using the system menu.''
 
There still needs to be work done to create own maps and flatfields but the cameras are still very capable and useable with fully cleared maps.
 
To clear the maps, just go to these offsets and fill with values around 0x3F or 0x0 for total length of  X Resolution x Y Resolution x 2 bytes (0x96000 for 640x480)

===Automatic Dead Pixels and Flatmap Correction===
It it possible to generate a new flat and dead pixel map automatically within the camera after flashing the cleared-map binary.
<br />
=====Dead pixels:=====
In the secret menu "System", navigate to Area - DeadPixelModel and set the AutoBP (sensitivity for auto bad pixel finding) to 50 or so. Then press C Button
This can take a while.

Afterwards, navigate to S: and press + to save it.
<br />
=====Flatfield:=====
In the Debug menu navigate to R2 and press +
now place something '''Cold''' infront of the Camera with a high emissivity. (it needs to fill the whole image)
Press '''+''', wait for it to says High temperature.


Place something '''Hot''' infront and press '''+''' again. 
Afterwards, save with '''S:''' again.
Flatfield should now be calibrated
<br /><blockquote>Note: Not all dead pixels are auto detected or get removed. you can manually select them in the Dead pixel editor but its not known yet how to select and correct them.</blockquote>

To interface, you need to make a adapter board with a DF12-50DS-0.5V(86) Docking socket.

A open source project can be found here, it includes pin access to:


The breakout board files can be found [https://oshwlab.com/gamerpaddy/d8x3c-backpack-usb here] but may be still work in progress.
*FPGA JTAG
*UART 3.3V with pin compatible FT232 socket
*Power 5V over USB-C
*5 Button inputs
*Buffered video output and socket for USB Videograbber
*Digital 14 bit video out header with hsync vsync and clk.
*


the pcb layout has been tested and seems to work.

==Sending Serial Commands directly over UART==
Sending Serial commands directly over UART to the core requires some additional bytes.
The packet structure is as follows (Strip spaces, commands are allways uppercase and 3 chars)
<STX> <LENGTH1> <LENGTH2> Command, Value, Checksum <ETX>
Pseudocode to craft a command packet may look like this<syntaxhighlight lang="c">
//cmd is allways 3 byte uppercase chars
//values can be multiple comma seperated like 320,240
function make_packet(cmd, values):
    payload = cmd + "," + join(values, ",") + ","
    bytes = ascii(payload)
    length = len(bytes)
    checksum = sum(bytes) mod 256
    return [0x02, length&0xFF, length>>8] + bytes + [checksum, 0x03]
