1. value = knxdatatype.decode ( event.datahex, dt.bool )
2. data = string.format ( '%s value is %s' , os.date ( '%c' ) , tostring ( value ))
3. -- write to the end of log file preserving all previous data
4. file = io.open ( '/mnt/usb/log.txt' , 'a+' )
5. file: write ( data .. ' \r\n ' )
6. file:close ()
Output:
Mon Jan 3 05:25:13 2011 value is false
Mon Jan 3 05:25:14 2011 value is true
Mon Jan 3 05:25:32 2011 value is false
Mon Jan 3 05:25:33 2011 value is true
Example: Read data from file (config in format key=value)
1. for line inio.lines ( '/mnt/usb/config.txt' ) do
2. -- split line by '=' sing
3. items = line:split ( '=' )
4. -- two items, line seems to be valid
5. if #items == 2 then
6. key = items [ 1 ] :trim ()
7. value = items [ 2 ] :trim ()
8. alert ( '[config] %s = %s' , key, value )
9. end
