Dali D8X3N Thermal Camera (view source)
Revision as of 18:17, 14 September 2025
, 18:17, 14 September 2025added professional pcb adapter
rev2 with temperature readout https://pastebin.com/u107Q85w
rev3 and onward will only be available directly as a Webpage on the Device (see below).
====Raw Viewer for the internal Webserver (recommended)====
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<br /u>'', check the contents of both files. FTP sometimes messes them up. also run dos2unix /app/web/webpages/cgi-bin/proxy.cgibecause linux <>windows difficulties that couldnt be resolved in over 30 years. <blockquote> performance may need improvement.</blockquote>
The [https://2477569.playcode.io/ Viewer Page] is written in JS and does not require any special dependencies, it can run as a plain html file offline.
==Using the Thermal module without Webserver==

to use it, you need to interface it directly.
To interface, you need to make have 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: *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]
</syntaxhighlight>
