README.md

This is the source code of the MMDVM firmware that supports D-Star, DMR, System Fusion, P25, NXDN, POCSAG, and FM modes.

It runs on the Arduino Due, the ST-Micro STM32F1xxx, STM32F4xxx and STM32F7xxx processors, as well as the Teensy 3.1/3.2/3.5/3.6. What these platforms have in common is the use of an ARM Cortex-M3, M4, or M7 processors with a clock speed greater than 70 MHz, and access to at least one analogue to digital converter and one digital to analogue converter.

In order to build this software for the Arduino Due, you will need to edit a file within the Arduino GUI and that is detailed in the BUILD.txt file. The STM32 support is being supplied via the ARM GCC compiler. The Teensy support uses Teensyduino.

This software is licenced under the GPL v2 and is intended for amateur and educational use only. Use of this software for commercial purposes is strictly forbidden.
