This Python application is designed for a Raspberry Pi with a TRNG device (TrueRNG, TrueRNGpro, or TrueRNGoroV2). It reads in a number of bits from the TRNG at a user-specified interval and counts the number of 'ones'. The datetime and count are then stored in a .csv file and the bits collected are appended to a .bin file for control.
- Raspberry Pi with Python3 installed (https://www.tomshardware.com/reviews/raspberry-pi-headless-setup-how-to,6028.html - Refer to this guide if you want to setup a headless Raspberry Pi)
- A TRNG device (TrueRNG)
- Python 3.x
- lxterminal package installed (default in most Raspberry Pi distributions)
- The following Python packages: bitstring, python-dotenv, pyserial.
- Clone the repository in your Desktop folder:
git clone https://github.com/Thiagojm/rasp_rng.git
- Install the required packages if they are not already installed:
pip install bitstring python-dotenv pyserial
-
In the root folder edit the
variables.envto specify the sample size (in bits), the interval between samples, the duration for each data collection cycle, and the paths for the temporary folder. -
Give execute permissions to the scripts:
chmod +x /path/to/rasp_rng.py
- Create an autostart entry:
sudo nano /home/pi/.config/autostart/rasp_rng.desktop
- Insert the following content into the .desktop file, changing the path to the path of your script, save and exit the file:
[Desktop Entry]
Type=Application
Name=RaspRNG
Exec=/usr/bin/lxterminal -e "python3 /path/to/rasp_rng.py; bash"
- Make the .desktop file executable:
sudo chmod +x /home/pi/.config/autostart/rasp_rng.desktop
I recommend using a RTC to keep files with correct name and not overwriting old ones. Check: https://pimylifeup.com/raspberry-pi-rtc/
The scripts will run automatically on startup.
