+# bosch-bme690
+AI-generated Rust port of the official Bosch BME690 environmental sensor driver.
+## About
+This crate provides a `no_std` Rust driver for the BME690 environmental sensor, based on the [official Bosch C driver](https://github.com/boschsensortec/BME690_SensorAPI). The implementation has been automatically translated and verified to match the floating-point calculation formulas from the original C driver.
+## Features
+- ✅ Temperature measurement (°C)
+- ✅ Pressure measurement (Pa)
+- ✅ Relative humidity measurement (%)
+- ✅ Blocking and async implementations using `embedded-hal` traits
+- ✅ `no_std` compatible
+- ✅ Calculation formulas verified against official C driver
+## Limitations
+- Gas resistance measurement not yet implemented
+- Only forced mode supported (no sequential/parallel modes)
+- Basic configuration only (1x oversampling)
+## Usage
+### Blocking
+```rust
+use bosch_bme690::{AsyncBme690, DeviceAddr, Measurement};
+use embassy_time::Delay;
+// Create driver instance
+let i2c = /* your I2C peripheral */;
+let delay = Delay;
+let mut bme = AsyncBme690::new(i2c, delay, DeviceAddr::Primary).await.unwrap();
+// Take measurements
+let data = bme.measure().await;
+println!("Temperature: {} °C", data.temperature);
+println!("Pressure: {} Pa", data.pressure);
+println!("Humidity: {} %", data.humidity);
+```
+### Async (embassy-rs)
+```rust
+use bosch_bme690::{AsyncBme690, DeviceAddr};
+use embassy_time::Delay;
+let i2c = /* your async I2C peripheral */;
+let delay = Delay;
+let mut bme = AsyncBme690::new(i2c, delay, DeviceAddr::Primary).await.unwrap();
+loop {
+    let data = bme.measure().await;
+    // Use measurement data...
+    Timer::after_secs(1).await;
+}
+```
+## I2C Addresses
+- **Primary (0x76)**: SDO pin connected to GND - use `DeviceAddr::Primary`
+- **Secondary (0x77)**: SDO pin connected to VDD - use `DeviceAddr::Secondary`
