Driver for LR1110 radio
This project has moved to LR11xx driver project.
The source code remains available but will not be maintained.
This package proposes an implementation in C of the driver for LR1110 radio component.
The driver is split in several components:
- Register / memory access
- System configuration
- Wi-Fi Passive Scanning
- GNSS Scan Scanning
- Crypto engine
This component is used to update the firmware.
Register / memory access
This component is used to read / write data from registers or internal memory.
This component is used to interact with system-wide parameters like clock sources, integrated RF switches, etc.
This component is used to send / receive data through the different modems (LoRa and GFSK) or perform a LoRa CAD (Channel Activity Detection). Parameters like power amplifier selection, output power and fallback modes are also accessible through this component.
Wi-Fi Passive Scanning
This component is used to configure and initiate the passive scanning of the Wi-Fi signals that can be shared to request a geolocation.
This component is used to configure and initiate the acquisition of GNSS signals that can be shared to request a geolocation.
This component is used to set and derive keys in the internal keychain and perform cryptographic operations with the integrated hardware accelerator.
Each component is based on different files:
- lr1110_component.c: implementation of the functions related to component
- lr1110_component.h: declarations of the functions related to component
- lr1110_component_types.h: type definitions related to components
The HAL (Hardware Abstraction Layer) is a collection of functions that the user shall implement to write platform-dependant calls to the host. The list of functions is the following:
