I have recently realised that the DALI protocol seems widely known as being sensitive to noise? DALI libraries require the micro to use interrupts to sense the bits coming in. Are there any comms protocols that don’t depend so heavily on interrupts to detect the edge of the next bit in the stream?…interrupts are dreadfully sensitive to noise…so bits may be misinterpreted. Surely its best to just have sync bits now and again, and then do a bit_sense at intervals of the bit period….possibly even sensing the logic level in each “bit window” multiple times, and then only believing it’s a one or zero if most of the sensing results were logic high, (or low).
So what are the most noise insensitive comms protocols that can transmit/receive at up to USB 2.0 frequencies?
Is the key in differential signalling?
