Python for intel Galileo GEN2

1. Python for intel Galileo GEN2 TYWu

2. Software Download/Setup • "Bigger" Linux Image • Download the Arduino IDE for Galileo • https://communities.intel.com/docs/DOC-22226

3. Software Download/Setup • Unzip SDCard.1.0.4.tar • image-full-galileo folder is generated

4. Software Download/Setup • Copy all files/folder under image-full-galileo into your micro SD card • Your SD directory structure should look like:

5. Running "Bigger" Linux Image (Option 1) • Unplug the USB connector of Galileo • Remove the Galileo power • Plug in the µSD card. • Then power it back up. • Plug in the USB connector • The first boot may take a little longer than average.

6. Running "Bigger" Linux Image(Option 2) • Unplug the USB connector of Galileo • Remove the Galileo power • Plug in the µSD card. • Then power it back up. • Plug in the RS232-USB connector • The first boot may take a little longer than average. • You can use the terminal to verify that the bigger image is working. Try running Python, for example.

7. Running "Bigger" Linux Image • RS232 to USB • Connect (RS232  Galileo) • Black Wire  GND • White Wire  TXO • Green Wire  RXI

8. Running "Bigger" Linux Image • Install Driver • Download the File http://www.prolific.com.tw/UserFiles/files/PL2303_Prolific_DriverInstaller_v1_10_0_20140925.zip • Unzip • Install

9. Running "Bigger" Linux Image • Install Tera Term • http://en.sourceforge.jp/projects/ttssh2/releases/ • Download teraterm-4.80.exe • Execute teraterm-4.80.exe for installation

10. Running "Bigger" Linux Image • Open Tera Term • Select Serial • Select COMxx: Prolific … • SetupSerial Port • Change Baud rate to 115200 • SetupFont

11. Running "Bigger" Linux Image • In the Tera Term • Entry “Enter” • Enter “root” as login name

12. Python • The first program helloworld.py #!/usr/bin/python # Hello world python program print "Hello World!"; • Editor: vi • How to execute it? • chmod 755 helloworld.py • ./ helloworld.py

13. Python • The second program blink.py

14. Python • Install  wiring-x86  • In PC • Download wiring-x86-master • https://github.com/emutex/wiring-x86 • Unzip • Rename the folder name to wiring-x86 • Copy the wiring-x8 folderinto the home directory of your micro SD card

15. Python • Install  wiring-x86  • In Galileo • Install wiring-x86 in Galileo • Change Directory • /media/mmcblk0p1/wiring-x86 • Entry • python setup.py install

16. Python • program blink.py • Sorce • http://www.emutexlabs.com/project/209-introduction-to-wiring-x86-for-intel-edison-and-galileo-gen2

17. Python • program blink.py #!/usr/bin/env python import time from wiringx86 import GPIOGalileoGen2 as GPIO gpio = GPIO(debug=False) pin = 13 state = gpio.HIGH # Set pin 13 to be used as an output GPIO pin. print 'Setting up pin %d' % pin gpio.pinMode(pin, gpio.OUTPUT) print 'Blinking pin %d now...' % pin

18. Python try: while(True): # Write a state to the pin. ON or OFF. gpio.digitalWrite(pin, state) # Toggle the state. state = gpio.LOW if state == gpio.HIGH else gpio.HIGH # Sleep for a while. time.sleep(0.5) # When you get tired of seeing the LED blinking kill the loop with Ctrl-C. except KeyboardInterrupt: # Leave the LED turned off. print '\nCleaning up...' gpio.digitalWrite(pin, gpio.LOW) # Do a general cleanup. Calling this function is not mandatory. gpio.cleanup()
