A ZigBee sniffer based on STM32F4Discovery board and OLIMEX MOD-MRF24J40 radio module
In this repo you can find a library to work with MRF24J40 module. This library is designed only for sniffing purposes and I have no guaranties that it will work in other conditions.
Note: You can find documentation in docs folder of this repository
LCD Display for this sniffer - WH2004A LCD display with character generator - has to be connected via I2C interface. Library for given LCD was borrowed from [this source](https://petoknm.wordpress.com/2015/01/04/ serial-lcd-driver-for-stm32/). Data shown on display is very small - that's because of lack of space on display. I had to use acronyms to show something more than just frame type.
Pinout for STM32F4:
Pinout for MRF24J40 can be found in OLIMEX Data Sheet.
