Rust embedded-hal driver for the A7105 2.4GHz FSK/GFSK Transceiver

1 unstable release

0.1.0 Nov 27, 2023

#439 in Embedded development





a7105 is a Rust crate that provides a high-level interface for interacting with the A7105 2.4GHz FSK/GFSK Transceiver, built on top of embedded-hal traits. This crate supports both synchronous (sync) and asynchronous (async) APIs, allowing users to choose the mode that best fits their application requirements.

This crate makes no assumptions for the protocol, if any, used on top of the a7105. Instead, the responsibility of this crate end at configuring the radio and reading/writing raw bytes over the air.

Sync and Async support is through embedded-hal and embedded-hal-async, configurable through the async and blocking features. By default the crate will use async variants. If blocking APIs are preferred, the blocking feature can be specified and default features disabled.

Getting Started


Add the following line to your Cargo.toml file:

a7105 = "0.1.0"

Example (Async)

This example utilizes the default async APIs. The blocking API has the exact same function signatures.

use a7105::prelude::*;

// Get a handle to the SPI peripheral attached to the A7105. This step
// will be highly specific to the hardware used and if a blocking or 
// async peripheral is being used
let spi = unimplemented!();

let mut radio = A7105::new(spi);

// It is usually a good idea to reset the radio before anything else

// Write a register, in this example setting IdData to 0x01234567
radio.write_reg(registers::IdData { 
    id: 0x01234567

// Read a register, in this example `DataRate`
let data_rate: registers::DataRate = radio.read_reg().await.unwrap();

// Transmit the given bytes 
radio.tx(&[0, 1, 2, 3]).await.unwrap();

// Receive a set number of bytes into the provided buffer
let mut buf = [0; 8];
radio.rx(&mut buf).await.unwrap();

// Set the radio's mode

// Destroys the radio instance and gets back the SPI peripheral
let spi = radio.destroy();
