This is the code to for Fourier Fencing Systems. This project makes use of a Raspberry Pi and a MCP3008 ADC to detect certain frequecies sent from a transmitter. An LED lights up when the frewuency is detected. The raw data gotten from the ADC is displayed on QT as well as the IIR frequency component and when a required frequency is detected, a signal is sent via Bluetooth to an Android Device. The Android code is in a different repo -https://github.com/FourierFencing/fourierfencingclient.

1. A Raspberry Pi
2. The git commandline tool on the RPi
3. MCP3008 ADC
4. An LED
5. Android Studio and a debugging device

From the RPi, clone this archive:

git clone https://github.com/FourierFencing/Team8-FFS.git

Open the directory

cd Team8-FFS

Then compile the code

qmake QTTest2.pro

make

1. startx ./Team8-FFS

1. startx ./Team8-FFS
2. Start the Fourier Fencing app on Android device and connect to "raspberry pi"
