RS232 Spectrum Analyser

This project came from the idea that I needed a simple, light spectrum analyzer which couldĀ be easily interfaced to embedded applications. This design was a proof of concept which made use of a RFM22B radio module and a PIC16F690. A simple GUI was also constructed for initial testing purposes. Photos of the prototype can be seen below. Source code for the proof of concept can be found downloaded here:
