- Arduino Yun Boot watcher
-
- Allows you to use the Yun's 32U4 processor as a
- serial terminal for the linino processor
-
- Upload this to an Arduino Yun via serial (not WiFi)
- then open the serial monitor at 115200 to see the boot process
- of the linino processor. You can also use the serial monitor
- as a basic command line interface for the linino processor using
- this sketch.
-
- The circuit:
- * Arduino Yun
-
- created March 2013
- by Massimo Banzi
- modified 26 May 2013
- by Tom Igoe
-
- This example code is in the public domain.
