DALI commands

[admin]

CANx-DALI sends all received bus telegrams which you can get capture via a script and parse as needed:

Code:

if not canx then
  canx = require('applibs.canx')
  canx.getlistener(1)

  function parse(frame)
    local hdr = frame:byte(1) or 0
    local typ = bit.rshift(hdr, 4)
    local len = bit.band(hdr, 0x3)

    -- bus data frame type
    if typ == 7 and len > 0 then
      loghex(frame)
    end
  end
end

canx.step(function(msg)
  -- message from CANx device 0.1
  if msg.lineid == 0 and msg.nodeid == 1 and msg.objectid == 1
    and msg.frombus and type(msg.data) == 'string' then
    parse(msg.data)
  end
end)
