Transcript Python for Galileo GEN2

Python for intel Galileo GEN2
TYWu
Software Download/Setup
• "Bigger" Linux Image
• Download the Arduino IDE for Galileo
– https://communities.intel.com/docs/DOC-22226
Software Download/Setup
• Unzip SDCard.1.0.4.tar
– image-full-galileo folder is generated
Software Download/Setup
• Copy all files/folder under image-full-galileo into
your micro SD card
• Your SD directory structure should look like:
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.
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.
Running "Bigger" Linux Image
• RS232 to USB
– Connect (RS232  Galileo)
• Black Wire  GND
• White Wire  TXO
• Green Wire  RXI
Running "Bigger" Linux Image
• Install Driver
– Download the File
http://www.prolific.com.tw/UserFiles/files/PL2303_Pr
olific_DriverInstaller_v1_10_0_20140925.zip
– Unzip
– Install
Running "Bigger" Linux Image
• Install Tera Term
– http://en.sourceforge.jp/projects/ttssh2/releas
es/
– Download teraterm-4.80.exe
– Execute teraterm-4.80.exe for installation
Running "Bigger" Linux Image
• Open Tera Term
– Select Serial
• Select COMxx:
Prolific …
– SetupSerial Port
• Change Baud rate to
115200
– SetupFont
Running "Bigger" Linux Image
• In the Tera Term
– Entry “Enter”
– Enter “root” as login
name
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
Python
• The second program blink.py
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 folder into the home directory of
your micro SD card
Python
• Install wiring-x86
– In Galileo
• Install wiring-x86 in Galileo
• Change Directory
– /media/mmcblk0p1/wiring-x86
• Entry
– python setup.py install
Python
• program blink.py
– Sorce

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
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()
