  1. Lab 5 Environment setup • BeagleboneLibrary for Python • Introduction to Python • Programming exercise

  2. Beaglebone Library for Python • Library for Beaglebone– PyBBIO • Including bbio libraries and so on. • Provides pin configuration and functions we need when programming. • Download and update from internet.

  3. Beaglebone Library for Python • Step1Connect Beagleboneto PC through USB cable and to router(DHCP supporting) by Ethernet cable . • Step2 Log in to your Beaglebone with Terminal program. • Step3 Make sure your beaglebone getting on the Internet.Using ping instruction.Ex: ping google.comEnd it by using Ctrl+c

  4. Beaglebone Library for Python • Step4 Download BeagleBone Library for Pythonpython-distutils, python-mmap, python-pyserial and PyBBIO • Type in ↓opkg update && opkg install python-distutils python-mmap python-pyserial

  5. Beaglebone Library for Python • Type in↓cd ~/*Changes to root directory

  6. Beaglebone Library for Python • Type in ↓git clone git://github.com/alexanderhiam/PyBBIO.gitLoad(Clone) PyBBIO.git to your Beaglebone. • Check “root” directory by ls, make sure there is a folder “PyBBIO”

  7. Beaglebone Library for Python • Step5 Change directory to PyBBIO and see if there is a file setup.py

  8. Beaglebone Library for Python • Step 6 Install PyBBIO by ↓python setup.py install • All will get ready when installation has done.

  9. Introduction to Python • Python has been provided in our Beaglebone OS • Type in python –V for checking version.

  10. Introduction to Python • Type in python for getting into conversation mode

  11. Introduction to Python • Try to input >>> a=5>>> b=3>>> a+b>>> a-b>>> a*b>>> a/b>>>a%bafter ‘>>>’ • See what happened.

  12. Introduction to Python • Use quit() to leave conversation mode.

  13. Introduction to Python • Write a python source code file with .py . • Run Python source code bypython xxx.py

  14. Introduction to Python • Printprint xxxprint ‘xxx’ or print “xxx”print value • Print multiple objectprint ‘abc’, 10result = root@beaglebone:# abc 10 • raw_input()raw_input(“Index”)

  15. Introduction to Python • Flow control • If [condiction]: statement 1elif [condiction]: statement 2else: statement 3 • Distinguish statement by indent.

  16. Introduction to Python • while [condiction]: statement statement statement

  17. Introduction to Python • for [var] in range([init.], [term.], [step]):statementEx: for i in range (1, 16, 3 ) • for [var] in [array]:statementEx: for j in my_array

  18. Introduction to Python • Nest loop • for [var] in range(): for [var] in range(): statement2 statement1

  19. Programming exercise • 1. Write a program enable you to input your Student ID and nickname.Print out the information.

  20. Programming exercise • 2. Write the instructions we mentioned in example of conversation mode into a file and execute it.Print the results.

  21. Programming exercise • 3. Print out the 9*9 table. Using flow control statement.
