Hardware Abstraction Layer (HAL) for IBM's LMIC 1.6 communication stack
|
|
|
|
|
targeted to RPi and Dragino LoRA/GPS HAT.
|
|
|
|
|
|
|
|
|
|
The goal was to keep the LMIC 1.6 sourcecode untouched, and just provide a
|
|
|
|
|
Hardware Abstraction Layer (HAL) for Raspberry Pi and Dragino LoRa/GPS HAT.

## Installation
|
|
|
|
|
|
|
|
|
|
### WiringPi
|
|
|
|
|
To control the RPi's GPI ports, the WiringPi GPIO interface library has to
|
|
|
|
|
be installed. On some operating systems WiringPi is already installed per
|
|
|
|
|
default. For instructions on manual installation please refer to the
|
|
|
|
|
following site:
|
|
|
|
|
http://wiringpi.com/download-and-install/
|
|
|
|
|
|
|
|
|
|
### Enable SPI interface
|
|
|
|
|
Per default, the SPI ports on the Raspberry Pi are disabled. You need to
|
|
|
|
|
manually enable them using raspi-config.
|
|
|
|
|
Follow the instructions given here:
|
|
|
|

This example does not use radio, it just periodically logs a counter value.

Can be used to checked if the timer implementation on RPi works as expected.
