Process received data

[Rick]

Try this as a resident script. Edit serial.open with correct port name and settings.

Code:

1234567891011121314151617181920212223242526

if not port then   require('serial')   port = serial.open(...)   function read()     local buf = {}     while true do       local timeout = #buf > 0 and 0.5 or 15       local char = port:read(1, timeout)             if char then         buf[ #buf + 1 ] = char:byte()       else         return buf       end     end   end end res = read() log(res) if #res == 16 then   -- process 16 bytes of data end

Return value for read function is a table containing bytes that have been read converted to numbers. It assumes that there's at least 0.5 seconds between consecutive messages. You can edit the timeout value to suit your needs.

How can I extract the 12th or 13th data separately from the 16 reads？
