This repository includes resources that I developed while using the AD5933 impedance sensor.
The python script "AD5933Interface.py" is a script intended for use on the Raspberry Pi as a point of high level interaction without the need for a microcontroller. Once data is obtained, it can very quickly be analyzed in Raspbian directly as a CSV. The SMBus2 library (used for I2C communication wrappers) is the only dependency that must be installed outside of the natively supported python libraries.
The "AD5933.X" directory contains the MPLAB X project that I developed as an example for using the AD5933 with a microcontroller. The project is using specifically the PIC24FJ64GB002 (one of the PIC24 chips included with the Microstick 2 development kit), but can be reconfigured as long as the MCC pregenerated I2C libraries are regenerated for the new PIC device. Otherwise, it is a simple bare metal microcontroller program where pins are set high after a certain percentage change is made from the initial measured impedance.
