Notes de mise en route
"Quick Start Guide", Section 11
If you want to use WiFi, you must follow these steps. The WiFi driver is not present in the Linux image in SPI flash because it is too large. The Linux SD image also includes ALSA, V4L2, python, SSH, node.js, and openCV.
Linux Python script from Arduino sketch
/*
This example uses Linux system calls to create a python script which writes
number 0-9 to a file, log.txt, one number per second. Then execute the
python script in the background, and regularly read the contents of the logfile
in the sketch while the python script is updating it.
