  1. I have considerable experience in reverse engineering protocols what with protocol design being part of my day job. However, being in the intellectual property business myself, I personally decided years back to only reverse engineer protocols when either my arm is twisted or it's for a protocol no longer in production and the engineering documents are lost to antiquity. (I don't include the normal sniffing one does when two implementations of a protocol don't interoperate as an exercise in RE.) So, while doing an RE on LOR is likely straightfoward, it's not something I myself would do. And I do recognize this as a personal choice thing: I don't mean to be judging anyone who feels differently. PICs are fun. I started using them back in the late 80's shortly after General Instruments sold off the division. These days I sort of favor AVRs since there's nice tool chains for the Mac, but they're both real fine choices. (Well, if I have to write in assembler, I'll pick an AVR any day over a PIC ;-) Cheers, Dan
  2. Interesting idea, using X10 this way. Certainly hadn't occurred to me. There's plenty of implementations of X10 for AVRs and PICs and I've even used it in an AVR project. Rolling serial interfaces is no big deal if necessary. I may play around some with this but am already going down a LOR -> DMX 512A route as I already have an iDMX-1000 and it will also work from a controller playing from flash (or aux. SD card). Thanks for the suggestion! Cheers, Dan
  3. Has the LOR protocol ever been publically released? Reason I ask is that I'm often making little PIC and AVR based microcontrollers for various halloween and christmas displays (RGB LED lighting, sensors, odd sounds, servos). Presently, I trigger them with a LOR channel which then sends them juice via a relay (poor man's DIO board) which they then notice. Would be more interesting and flexible to implement a subset of LOR and have them listen on the daisy chain. Lacking a spec for LOR, I can just as readily use my LOR <-> DMX converter and implement DMX 512. Yeah, yeah, I could get DIO and ServoDog boards, but other than knowledge of the LOR protocol, I already build all of that myself and so do not have a serious need for them. (They ARE very neat and useful, I just happen to make my own point solutions for my specific needs.) Thanks, Dan
