ttyACM0?

[jimmayhugh]

I'm running Arduino IDE 1.0.5 and Teensyduino 1.16 on a Debian 7.1 system. When I open the IDE, the "Tools" menu shows "Serial Port: (emulated)" in greyed out text, and /dev/ttyACM0 is also absent.

I can compile and load code for the Teensy 3.0 and the Serial monitor shows /dev/ttyACM0, so I guess I'm confused.

I added the Teensy 3.0 udev rules a while back.

Am I missing something?

When you select something without Serial in Tools > USB Type, Teensyduino uses emulated serial, so the Arduino Serial Monitor can still work, even though Teensy isn't implementing a serial device (after you upload code compiled with that setting). In that mode, you can't select a serial port. The HID interface that's used to emulate the missing serial is detected automatically.

If you want real serial, just set Tools > USB Type back to "Serial".

Gotcha! Thanks!

Ahh thanks for that explanation. I was wondering why the serial monitor was working even though my devices were set to midi. It's so convenient to have the monitor to debug at all times !
