Art-Net DMX

[tomnord]

Try this:

Code:

if not server then   mapping = {     [1] = '32/1/1',     [2] = '32/1/2',     [3] = '32/1/3',   }   server = require('socket').udp()   server:settimeout(1)   server:setsockname('*', 0x1936)   header = 'Art-Net' .. string.char(0, 0, 0x50)   values = {}   function parse(data)     local count, value     if #data < 19 or data:sub(1, #header) ~= header then       return     end     local univlo, univhi = data:byte(15, 16)     local universe = univhi * 256 + univlo     if universe ~= 3 then       return     end     count = #data - 18     for i = 1, count do       value = data:byte(i + 18)       if value ~= values[ i ] then         values[ i ] = value         if mapping[ i ] then           grp.update(mapping[ i ], value)         end       end     end   end end data = server:receive() if data then   parse(data) end

When logging the "server" variable i get this status: udp{unconnected}: 0xb6e42ac0
