I've done a basic test sending a single
int value to Arduino from Processing via the Processing Serial library and all's fine. I would like to send multiple int values, but not entirely sure what's the best way to that.
Acoording to the docs Serial.write
writes bytes, chars, ints, bytes, Strings to the serial port
so one option would be to send a string I can split and get the values:
but I'm not sure how I would read the data convert when I receive it in Arduino.
Another thing that comes into mind is to use a
byte since I'm sending multiple values, but I haven't worked with bytes much, so any advice on how pack/unpack two into a
byte and back would be really handy.
