+This is the source code of ADF7021 version of the MMDVM firmware (MMDVM Hotspot), based on Jonathan G4KLX's MMDVM software. This firmware supports D-Star, DMR and P25 digital modes, System Fusion is still untested. 
 
 This software is intended to be run on STM32F103 microcontroller. You can build this code using Arduino IDE with stm32duino package, and also using "make" with ARM GCC tools. Also, Arduino with 3.3 V I/O is supported, this firmware works on Arduino Due and Arduino Zero.
