Probably if you add a [print] to the [comport] output you would get a list of 12 ASCII values for each sample.<br><br>In Pd you need to accumulate the list of incoming ASCII codes, subtract 48 (ASCII '0') from each, and route them accordingly. A 12-digit number won't display correctly as a float. Probably it's easier in Arduino to make your numbers ints on [0..255] and send them as BYTE. Then you get one number per sample and don't need to handle lists.<br><br>Martin<br><br> </body>
