    - PyCharm Professional version from www.jetbrains.com (request student or academic discount)
    (the Community and Edu version do not support remote interpreters)

  • Establish a TCP/IP link between the host system and the Raspberry Pi and start a SSH terminal session with PuTTY

  • As you see the script is remotely run by the command /usr/bin/python -u /home/pi/scripts /Ex1.py. For most Raspberry Pi programs the script must be executed with sudo permission. To achieve this, create a Linux script pyrun (or any other name) in /usr/bin/ (with execute permission) as shown to the right. (The -Qnew option requests floating point division. The file is provided in the RaspiBrick firmware distribution.)

    #! /bin/sh
    sudo python2.7 -Qnew $*

  • Under File | Settings | Project Interpreter click the wheel and select Add Remote.At the line Python interpreter path, click the right [...] button. A dialog opens where you can select the pyrun script.
