# Install Pyserial package with: python -m pip install pyserial # On Linux - may need to be root or set /dev/tty port permissions to 666 You can change blocksize or numloops to capture different amounts of data or modify the code for your own purposes There is a 1,024,000 byte “random.bin” file in the current directory that conatains the captured data This is what the output looks like when capturing with a TrueRNGpro. On a machine that has a functional TrueRNG install, Python 2.7, and Pyserial, you just need to download the python code (read_truerng_example.py) and run it from the directory where you put it with: python read_truerng_example.py Installing Python 2.7 and pyserial on Ubuntu Linuxįor Ubuntu (or other Linuxes that use apt), log in and issue the commands: sudo apt-get update sudo apt-get install python2.7 sudo apt-get install python-pip python -m pip install pyserial Should be good with the Python and pyserial install. To test the install, run “python” from a Command Prompt window and then try “import serial”. If this doesn’t work then your environment variables aren’t correct or you need to open up a new Command Prompt window to use

To install pyserial (Python serial port library), open up a Command Prompt window and use “python -m pip install pyserial” to install Your Python27 and Python27\Scripts directories here according to the install directory you chose. Choose the “Path” variable and click edit.
To get there in Windows 10, you use Window-x, click “system”,Ĭlick “Advanced system settings”, then click “Environement Variables”. Next, we need to add the Python directories to the path. This should install Python in c:\python\python2.7 or c:\python2.7 “Windows x86 MSI installer” for the latest version of Python 2.7 (currenly it is 2.7.12). On Windows, you go to the Python website and download the “Windows x86-64 MSI installer” or Installing Python 2.7 and pyserial on Windows 10 Or change to whatever device node that your system assigns to the device like: sudo chmod 666 /dev/ttyACM0
Note: on Linux, to access the TrueRNG as a user, you may need to modify the device node permissions to allow users to access the Will make it show up also as /dev/TrueRNG. Installing the udev rule per the instructions On Linux, you should see the device in your dmesg (i.e. You should see it come up in the device managerĪs a ‘Port’ (Window-x on the keyboard, then click Device Manager in Windows 10) On Windows, you download and install the.

We get questions about how to use our TrueRNG random number generators so I thought I would write a tutorial on how to get it running with Python on Windows and Linuxįirst – follow the instructions for installing the driver for the TrueRNG.
