SX1262 Radio Driver

A type-safe embedded-hal driver for the Semtech SX1261/2 sub-GHz radio transceivers. This crate provides a robust interface for controlling these highly integrated, long range, low power radio transceivers designed for ISM band applications.

Features

• Frequency Range: 150-960 MHz
• Modulation Support:
  • LoRa: SF5-12, BW 7.8-500kHz
  • (G)FSK: BR 0.6-300kbps
• Output Power:
  • SX1261: -17 to +15 dBm
  • SX1262: -9 to +22 dBm
• High Sensitivity: Down to -148 dBm
• Power Management: Integrated voltage regulation (DC-DC or LDO)
• Flexible I/O: Programmable DIO pins for interrupts and control
• no_std Compatible: Suitable for embedded systems
• Type-safe Interface: Built on regiface for reliable register access

Installation

Add this to your Cargo.toml:

[dependencies]
sx1262 = "0.1.0"

Usage

The main entry point is the Device type which wraps an SPI interface and provides methods for register access and command execution:

use sx1262::{Device, commands::operational::SetStandby};
use embedded_hal::spi::SpiDevice;

fn configure_radio<SPI: SpiDevice>(spi: SPI) -> Result<Device<SPI>, SPI::Error> {
    // Create new device instance
    let mut device = Device::new(spi);
    
    // Read/write registers
    let reg_value: /* register type */ = device.read_register()?;
    device.write_register(/* register */)?;
    
    // Execute commands
    let cmd_resp = device.execute_command(/* command */)?;
    
    Ok(device)
}

The driver is organized into modules for registers and commands:

• device: Main interface for hardware interaction

  • Wraps SPI communication
  • Provides register access methods
  • Handles command execution

• registers: Hardware register definitions

  • rf: Frequency, power, etc.
  • packet: Packet handling
  • dio: Digital I/O configuration
  • system: System configuration

• commands: Control interface

  • rf: RF/modulation configuration
  • dio: Interrupt control
  • operational: Mode control
  • status: Monitoring and statistics
