Digital Voice Modem Firmware (Hotspot)

The DVM firmware provides the embedded microcontroller implementation of a mixed-mode DMR/P25 or dedicated-mode DMR or P25 repeater system. The firmware; is the portion of a complete Over-The-Air modem implementation that uses an ADF7021 to provide a raw RF interface.

This project is a direct fork of the MMDVM (https://github.com/jelimoore/MMDVM_HS) project.

Building

Please see the various Makefile's included in the project for more information. This project includes a few Makefiles to target different hardware. (All following information assumes familiarity with the standard Linux make system.)

Makefile - This makefile is used for targeting a generic STM32F103/ADF7021 device.
For STM32F103 using Ubuntu OS install the standard ARM embedded toolchain (typically arm-gcc-none-eabi).
1. Create a directory under "/opt" called "tools" and change to the directory:
```
mkdir -p /opt/tools
cd /opt/tools
```
1. Checkout https://github.com/juribeparada/STM32F10X_Lib to /opt/tools: git clone https://github.com/juribeparada/STM32F10X_Lib

Use the make command to build the firmware, choosing the appropriate makefile with the -F switch.
