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.
*/

char output[3];

void setup() {
  
  Serial.begin(115200);
  
  system("echo '#!/usr/bin/python' > myScript.py");
  system("echo 'import time' >> myScript.py");
  system("echo 'for i in range(10):' >> myScript.py");
  system("echo '    with open(\"log.txt\", \"w\") as fh:' >> myScript.py");
  system("echo '        fh.write(\"{0}\".format(i))' >> myScript.py");
  system("echo '    time.sleep(1)' >> myScript.py");
  system("chmod a+x myScript.py");
  system("./myScript.py &");     
}

void loop() {
  
  FILE *fp;
  fp = fopen("log.txt", "r");
  fgets(output, 2, fp);
  fclose(fp);
  Serial.println(output);
  delay(1000);
  
}

Accès via Telnet

// How to – Use Galileo Linux using an Ethernet cable and a home network Router(DHCP server)

void setup() {
    system("telnetd -l /bin/sh");
}

void loop() {
    system("ifconfig eth0 > /dev/ttyGS0");
    sleep(20);
}

Accès SSH

Par defaut, la distribution fournie n'inclut pas de serveur SSH.

Pour y remedier, Intel met a disposition une image plus complete qui entre autre, en possède un: https://communities.intel.com/docs/DOC-22226 (LINUX IMAGE FOR SD for Intel Galileo)

Une fois telechargé, voir la section 11 du document "Quick Start Guide" pour mettre cette image sur une micro-SD.

Après avoir récupérer l'adresse IP via le programme décrit dans la section précédente, faire simplement un ssh root@adresse_ip pour se connecter a la carte
