It was a question of sending the right code.
When I started this attempt, I had the idea, that I should send the following command from a Beo4 remote: press "Light" and press "Green" (or any of the other colors) in order to control an LK FUGA TOUCH UNI350 dimmer.
http://www.lk.dk/produkt/5703302141772 (probably the most common dimmer in Denmark)
You supplied me with the following two Raw codes:
Code: Select all
Light = +200, +2925, +200, +2925, +200, +15425, +200, +2925, +200, +6050, +200, +6050, +200, +6050, +200, +9175, +200, +6050, +200, +2925, +200, +9175, +200, +6050, +200, +6050, +200, +2925, +200, +6050, +200, +9175, +200, +6050, +200, +2925, +200, +9175, +200, +6050, +200, +12300, +200,
Green = +200, +2925, +200, +2925, +200, +15425, +200, +2925, +200, +6050, +200, +6050, +200, +6050, +200, +6050, +200, +6050, +200, +6050, +200, +6050, +200, +6050, +200, +9175, +200, +6050, +200, +2925, +200, +9175, +200, +2925, +200, +9175, +200, +2925, +200, +9175, +200, +12300, +200,
These two codes are correct readings, but they do not work for controlling the dimmer. If I convert only the datapart of the two codes above to burst pairs, I get:
Code: Select all
Light = RRR1R01R - R0R1R01R
Green = RRRRRRRR - 1R010101
If I then use this document:
https://www.mikrocontroller.net/attachm ... talink.pdf (page 5) to convert the B&O burst codes to binary, I get:
Code: Select all
Light = 00011011 - 10011011
Green = 00000000 - 11010101
Converting to Hex I get:
Code: Select all
Light = 0x1B - 0x9B
Green = 0x00 - 0xD5
Refering to this link:
https://github.com/christianlykke9/Beom ... Commands.h the Hex codes for Light and green are:
So the Raw codes convert correctly, but the dimmer doesn't react to them. I also tried to use Georges BnO code to send the Hex codes: 0x9B + 0xD5, which didn't work either. After looking at the code, i could see, that what I was sending in Hex was actually:
Code: Select all
Light = 0x01- 0x9B
Green = 0x01 - 0xD5
Note the difference in the first byte. This is because Georges code "pads" an extra byte 0x01 onto the data:
from this:
https://forum.beoworld.org/forums/p/11816/191651.aspx and this
https://github.com/christianlykke9/Beom ... eomote.cpp
It seemed, that the first byte in the B&O data part of the IR code was an address byte, and the second byte was a command byte. All the values for the command byte seems wery well described in both Georges code, and in the beomote link above. I havn't been able to find any description of what values for the address byte should be used, but this document:
http://mlgw.bang-olufsen.dk/source/docu ... to0240.pdf
Describes in part 4.2 four values, where 0x01, as George uses seems to correspond to controling an Audio source, where 0x00 from the Raw Green code above suggests a video source being controlled. This link:
https://forum.beoworld.org/forums/p/11816/191651.aspx suggested, that an address byte value of 0x1b should correspond to Light sources being controlled, which interestingly corresponds to the address byte of the Raw Light code being sent above.
So I tried sending:
Code: Select all
0x1B + 0xD5 (destination byte = Light, command byte = Green)
, which works perfectly.
I have tried looking for a list of address byte values, but without luck, except from what I've listed, but it seems they can be derived from the Raw codes, by looking af the first databyte in the Raw code, when pressing the nine source buttons (TV, Light, Radio, DTV, DVD...etc.) .
Perhaps because I have got it working
