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.
- 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_stdCompatible: Suitable for embedded systems- Type-safe Interface: Built on
regifacefor reliable register access
Add this to your Cargo.toml:
[dependencies]
sx1262 = "0.1.0"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 = device.read_register(/* register */)?;
device.write_register(/* register */)?;
// Execute commands
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
