ClipBoard Communication PC Pi With Python

I normally use my Raspberry-Pi on a windows shared desktop. I also share a network drive with the Pi. This is great, but I still have the annoyance of the clipboard on the PC not being reflected on the Pi. There may be cross platform apps out there for this problem, but I though it would be more fun to try to make my own solution using Python. It was fun, useful, and you can learn a bit of Python from it. In the end it took only about 100 lines of code to do the job. Everything here is open source, no purchases required. This instructable does assume that you know your way around the Raspberry-Pi and have some minimal knowledge of Python. If you do not check instructables and the web where you will find lots of information. Some references are included here, but just a tiny, tiny fraction of what is out there.ClipBoard Communication PC Pi With Python

Step 1: Tools and Materials

Tools and Materials

This is what I used, adapt the list to your environment, many variations are possible.

On the PC

  • Windows 7, but any version should do. On the PC side Ubuntu or Mac OS should also work ( not tested ).
  • I used Python 2.7 any version from about 2.6 up should work, I have not tried Python 3.
  • I used an IDE called Spyder which I highly recommend ( if you have not used a Python IDE, and do much programming then get it ), but you could do it all in just a text editor or with Idle ( included in most Python installations ). Spyder is installed as part of Anaconda if you want it, get it at
  • You probably need to beef up your Python with rpyc and pyperclip. From the command line the following should do it: ( run from cmd )

pip rpyc

pip pyperclip

  • I have a shared drive with the PI, but any method that helps get files between the computers is useful.
  • I also share the PI desktop with the PC, this is useful, but not necessary.

On the Pi

  • I used Raspbian installed originally from NOOBS but other other OS versions should work if they have Python installed.
  • Again Python probably needs beefing up. The following commands did this for me: ( run from a terminal)

sudo apt-get install python-pip

sudo pip install rpyc

sudo apt-get install xsel

sudo pip install pyperclip

Step 2: ​Try It


  • Get the files from the instructable and download to both computers. They are and
  • Either the Pi or the PC can run either program or both at the same time, but start with one program on each.
  • To make the programs work you need to know the tcp/ip address of the computer that is running rpc_copy. This computer is where the copying takes place, I will call it the rpc_copy computer.

On windows you can find the tcp/ip address from the command line ( run cmd ) with ipconfig.

On the PI you can find tcp/ip address by running ifconfig in a terminal window.

  • When you have the address, code it in the program using what ever Python editor you use. Idle which comes with Python, is fine for this and has a menu option to launch the program when you are ready.
  • On the computer where you are running rpc_paste, no edits are necessary.
  • First start rpc_paste on the rpc_paste computer then rpc_copy on the other. Leave them running both places. You can start rpc_paste first but if it cannot connect in the first minute or so ( adjustable in the code ) it will give up.
  • You should now be able to copy from the rpc_copy computer and paste to the rpc_paste computer.
  • If you run both programs on both machines then you can copy and paste both ways.

Step 3: ​How it Works and Comments

How It Works and Comments

One of the best way to understand how a computer program works is to read and investigate its source code. I have included fairly well commented programs you should do that. However, a brief high level overview may help. The basic technique used here is called Remote Procedure Call or RPC. It uses the Ethernet connection between the two computers to communicate. This should work between any two computers at any distance if they are on the same network and have the proper ports open. The OS should not matter as long as they support Python and the modules that extend them.

We use two modules that are often not in the distribution of Python:

  • rpyc: module supports a fairly simple RPC connection between computers.
  • pyperclip: module supports access to system clipboard.

RPC from your PC to the Pi has many more uses than just clip board communication. You can fairly easily control any Pyton progrm on the Pi from your PC ( and vise versa ).
