1-wire keyfob and reader

[Jose]

You can use this function to list devices on a certain 1-Wire bus:

Code:

require('ow')

function list(bus)
 local res = {}
 local dir = ow.dir('/uncached/bus.' .. bus) or {}
 for _, entry in ipairs(dir) do
   local chunks = entry:split('/')
   if #chunks == 4 and chunks[ 4 ]:match('^%x%x%.') then
     res[ #res + 1 ] = chunks[ 4 ]
   end
 end

 return res
end

log(list(0))
log(list(1))

Thank you very much.
I will try it.
