This is correct - I only built daliserver around the Tridonic/Lunatone DALIUSB device. I didn't have anything else available back in 2011. If you're looking for something more generic, please...

I think I've seen what you mentioned, but it's been a while, and I didn't investigate further because I was happy with sending commands and receiving responses. At some point,...

This will surely help: http://ww1.microchip.com/downloads/en/appnotes/01465a.pdf

I absolutely agree. Did you find out how Tridonic transmits 24bit messages on the USB port already? I currently lack the time to do more reverse engineering myself. I'm also...

Humm. Ok. I have no idea where exactly the priority comes in, but I guess it's part of the DALIUSB message. My test rig consisted of a Linux PC, a...

Perhaps we should finally design and build a custom DALI USB interface to address the terrible lack of documentation? Or a Raspberry Pi Hat?

@rnixx Good find. The Arduino library mentioned there uses bit banging to drive the bus. The circuit seems a bit primitive, though. No galvanic isolation, and the Arduino is powered...

This circuit looks much better: https://mouser.com/applications/lighting-digitally-addressable/ It has polarity protection and galvanic isolation, as should be standard for this sort of device.

Back when we reverse engineered the protocol, we were not sure what the 0x77 messages meant exactly. They were not relevant for basic operation anyway, so we did not pursue...

Thanks for investigating. Did you find out anything else about the message content? Or alternatively, can you send me sample packets? I will add a "Invalid packet received" message type...
