Thanks ..what none of the websites tell is what current the lamps have to pull from the DALI bus in order to transmit pulses back to the DALI controller....if the DALI is rated to 250mA.....then each lamp must be capable of pulling 250mA from the DALI bus in order to collapse it from 16V to 0V in order to send the low pulse.?
The bus is intended for hundreds of nodes, so 1 will never do that.Thanks, this is our DALI TX/RX circuit, but our TX circuit , as you can see, could never draw 250mA from the DALI bus. I will look into you kindly supplied docs.
The DALI-TX drive voltage is just 2.5V.
Thanks, it sounds like maybe you concur with me that 16MHz is way to high for an internal oscillator of a micro thats running simple DALI dimming signals in RX only....(its just a simple dimmable lamp).....DALI is 1200bits/sec, so i think our software guy has made the micro oscillator way too quick at 16MHz?The other requirements make no sense yet.
Thanks, though there might only actually be one lamp on the DALI bus......we have DALI for our outdoor lamps. but each lamp has its own DALI controller which just broadcasts dimming signals to it.The bus is intended for hundreds of nodes, so 1 will never do that.
