Don't get me wrong I love Xcode is is the best environment for developing desktop applications I have come across. But I don't think it is suited to an embedded situation. Take the instructions for opening up the serial monitor window:-
- Open /Applications/Utilities/Terminal.app
- The the command prompt in the new terminal window type (without the quote marks),
o "screen /dev/tty.usbserial"
o Hit the Tab key. The rest of the serial port's name should appear. If it doesn't, verify that the Arduino is plugged in via serial and is powered on.
o For example, the command for my Arduino looks like: "screen /dev/tty.usbserial-A4001Jdl"- Press return to execute the screen command. The Arduino will reset and should open the serial port.
- You can type to send characters, but there is no local echo (ie. you won't see the typed characters)
- To exit and close the serial port
o Press Control-A then 'k' to "kill" the window. This just stops the screen program and returns to the command prompt.
Well I think just hitting the monitor button is a lot easer and more convenient.
