Re: DALI Interface Proposal

Hi,

This is another good document for our DALI project : https://www.nxp.com/files-static/microcontrollers/doc/ref_manual/DRM004.pdf

At the receiver side, if you start and synchronize a same frequency free running clock with the negative going "start bit" and ex-or the incoming frame with this clock then you decode the code and obtain the same data. This is the same technique how I designed and made Turkey's first military digital voice scrambler unit 40 years ago :)
