BME680 Rust Library
|
||||
=============
|
||||
|
||||
This repository contains a pure Rust implementation for the [BME680](https://www.bosch-sensortec.com/bst/products/all_products/bme680) environmental sensor.
|
||||
The library can be used to read the gas, pressure, humidity and temperature sensors via I²C.
|
||||
|
||||
It is a fork of the library written by Marcel Buessing: https://github.com/marcelbuesing/bme680.
|
||||
|
||||
To use this library, create a new project and add it as a dependency:
|
||||
|
||||
```toml
|
||||
[dependencies]
|
||||
bme680 = {git = "https://github.com/dnutiu/bme680-rust.git", version = "0.9.0"}
|
||||
```
|
||||
|
||||
# Getting started on Raspberry Pi
|
||||
|
||||
Assuming that you have connected the sensor to the Raspberry PI's GPIO ports.
|
||||
|
||||
Install required libraries for developing I2C.
|
||||
|
||||
```bash
|
||||
sudo apt-get install build-essential libi2c-dev i2c-tools python-dev libffi-dev
|
||||
```
|
||||
|
||||
Determine the I2C device path
|
||||
|
||||
```
|
||||
pi@raspberrypi:~ $ i2cdetect -y -l
|
||||
i2c-1 i2c bcm2835 I2C adapter I2C adapter
|
||||
```
|
||||
|
||||
Determine I2C-Address of sensor, `0x76` is the primary address, `0x77` is the secondary address.
|
||||
If in doubt determine the address via the following command:
|
||||
|
||||
```
|
||||
pi@raspberrypi:~ $ i2cdetect -y 1
|
||||
0 1 2 3 4 5 6 7 8 9 a b c d e f

||||

|

|
||||
```
|
||||
|
||||
The read-sensor-data from the examples folder is configured to use the I2C device `/dev/i2c-1` and the `0x76` address.
|
||||
|
||||
To run the example, clone the repository and go to the examples' folder:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/dnutiu/bme680-rust.git && cd bme680-rust/examples/read-sensor-data
|
||||
```
|
||||
Then run the example:
|
||||
|
||||
```bash
|
||||
export RUST_LOG=info
|
||||
cargo run
|
||||
```
