# Adafruit Feather M0 RFM95

## Installing the MCCI LMIC Library
[Adafruit Feather M0 with RFM95 Product Page](https://www.adafruit.com/product/3178)
[Adafruit Feather M0 with RFM95 Datasheets & Files](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/downloads).

From the Arduino IDE, open the Library Manager (Sketch->Include Library->Manage Libraries). In the search box, type MCCI and select the MCCI LoRaWAN LMIC library should be the first result.
## Required Arduino Libraries

## Board Support
### Important
Make sure you do not have other LMIC arduino libraries installed, otherwise you will experience
build errors. You can find your Arduino libraries for your operating system below, simply delete the directory if you would like to remove a library.

### Feather M0 RFM95 - Adafruit
linux: /home/{user}/Arduino/libraries
windows: Documents/Arduino/libraries
mac os: Documents/Arduino/libraries

1. Add Adafruit package index, instructions [here](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/setup).
2. Install both Arduino and Adafruit SAMD board support, instructions [here](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/using-with-arduino-ide#install-samd-support-6-5).
3. (Windows Only) Install drivers, instructions [here](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/using-with-arduino-ide#install-drivers-windows-7-and-8-only-6-11)
From the Arduino IDE, open the Library Manager (Sketch->Include Library->Manage Libraries). In the search box, type the library name below and install the latest version.

[IBM LMIC framework](https:/matthijskooijman/arduino-lmic)

### Required Configuration
This library requires that a config file be setup properly. After you have installed the `IBM LMIC framework` library, navigate to it's directory on your operating system found below. Next, replace the `config.h` file in this directory with this [config.h](https:/helium/longfi-arduino/blob/master/Sparkfun-Pro-RF/longfi-us915/config.h) file.

windows: Documents/Arduino/libraries/IBM_LMIC_framework/src/lmic
mac os: Documents/Arduino/libraries/IBM_LMIC_framework/src/lmic

## Required Arduino Board Support

1. Install Arduino SAMD Support, instructions [here](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/using-with-arduino-ide#install-samd-support-6-5).
2. Install Adafruit SAMD Support, instructions [here](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/using-with-arduino-ide#install-adafruit-samd-6-7).
3. (Windows 7 & 8 Only) Install drivers, instructions [here](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module/using-with-arduino-ide#install-drivers-windows-7-and-8-only-6-11)

#ifndef _lmic_config_h_

// In the original LMIC code, these config values were defined on the
// gcc commandline. Since Arduino does not allow easily modifying the
// compiler commandline, use this file instead.

// #define CFG_eu868 1

#define OSTICKS_PER_SEC (1000000 / US_PER_OSTICK)

// Set this to 1 to enable some basic debug output (using printf) about
// RF settings used during transmission and reception. Set to 2 to
// enable more verbose output. Make sure that printf is actually
// configured (e.g. on AVR it is not by default), otherwise using it can
// cause crashing.
#define LMIC_DEBUG_LEVEL 0

// Enable this to allow using printf() to print to the given serial port
// (or any other Print object). This can be easy for debugging. The
// current implementation only works on AVR, though.
//#define LMIC_PRINTF_TO Serial

// Any runtime assertion failures are printed to this serial port (or
// any other Print object). If this is unset, any failures just silently
// halt execution.
#define LMIC_FAILURE_TO Serial

// Uncomment this to disable all code related to joining
//#define DISABLE_JOIN
// Uncomment this to disable all code related to ping
//#define DISABLE_PING
// Uncomment this to disable all code related to beacon tracking.
// Requires ping to be disabled too
//#define DISABLE_BEACONS

// Uncomment these to disable the corresponding MAC commands.
// Class A
//#define DISABLE_MCMD_DCAP_REQ // duty cycle cap
//#define DISABLE_MCMD_DN2P_SET // 2nd DN window param
//#define DISABLE_MCMD_SNCH_REQ // set new channel

//#define DISABLE_MCMD_BCNI_ANS // next beacon start, automatical disabled by DISABLE_BEACON

// In LoRaWAN, a gateway applies I/Q inversion on TX, and nodes do the
// same on RX. This ensures that gateways can talk to nodes and vice
// versa, but gateways will not hear other gateways and nodes will not
// hear other nodes. By uncommenting this macro, this inversion is
// disabled and this node can hear other nodes. If two nodes both have
// this macro set, they can talk to each other (but they can no longer
// hear gateways). This should probably only be used when debugging
// and/or when talking to the radio directly (e.g. like in the "raw"
// example).
//#define DISABLE_INVERT_IQ_ON_RX

// This allows choosing between multiple included AES implementations.
// Make sure exactly one of these is uncommented.
//
// This selects the original AES implementation included LMIC. This
// implementation is optimized for speed on 32-bit processors using
// fairly big lookup tables, but it takes up big amounts of flash on the
// AVR architecture.
// #define USE_ORIGINAL_AES
//
// This selects the AES implementation written by Ideetroon for their
// own LoRaWAN library. It also uses lookup tables, but smaller
// byte-oriented ones, making it use a lot less flash space (but it is
// also about twice as slow as the original).
