hdc1080-embedded-rs - Driver for sensor temperature and humidity

Made on the model of a crate for HDC20xx

HDC1080 referenc

Designed for use with [embedded-hal]

Features

• Reading data from a sensor with one request read()
• Separate commands for reading temperature and humidity temperature() and humidity()
• Getting information about the sensor: get_device_id(), get_man_id(), get_serial_id()
• Low battery check: battery_low()

Usage

```rust

![deny(unsafe_code)]

![no_main]

![no_std]

extern crate cortexm; extern crate cortexmrt as rt; extern crate nb; extern crate stm32g0xxhal as hal;

use hal::{prelude::*, stm32, time::Hertz, i2c::Config}; use nb::block; use rt::entry; use embeddedhdc1080rs::Hdc1080;

fn main() { let dp = stm32::Peripherals::take().expect("cannot take peripherals"); let mut rcc = dp.RCC.constrain(); let gpioc = dp.GPIOC.split(&mut rcc); let gpioa = dp.GPIOA.split(&mut rcc); let mut delay = dp.TIM14.delay(&mut rcc); let mut led = gpioc.pc6.intopushpulloutput(); let sda = gpioa.pa10.intoopendrainoutput(); let scl = gpioa.pa9.intoopendrain_output(); let mut temp:f32; let mut hum:f32;

let mut timer = dp.TIM17.timer(&mut rcc);

let conf:Config = Config::new(100.khz());

let mut i2c = dp
    .I2C1
    .i2c(sda, scl, conf, &mut rcc);
let mut dev = Hdc1080::new(i2c, delay).unwrap();

dev.init().unwrap();
//hprintln!("device ID {:?}", dev.get_device_id().unwrap());
//hprintln!("manufacturer id {:?}", dev.get_man_id().unwrap());
//hprintln!("Serial ID {:?}", dev.get_serial_id().unwrap());
//hprintln!("curent config {:?}", dev.read_config().unwrap());

timer.start(500.ms());
loop {
    led.toggle().unwrap();
    let (temp, hum) = dev.read().unwrap();
    //hprintln!("temperature {}", temp);
    //hprintln!("humidity {}", hum);
    block!(timer.wait()).unwrap();
}

} ```
