1-wire keyfob and reader

[admin]

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))
