Crate tmp1075

TMP1075

A platform agnostic driver to interface with the TMP1075 temperature sensor. The driver supports async and blocking mode, selectable wit hthe async and blocking features.

TMP1075

Platform agnostic rust driver for the TMP1075 temperature sensor.

Can be used with async and sync I2C interfaces that implement the embedded_hal or embedded_hal_async traits.

• TMP1075 product page
• TMP1075 datasheet

Missing Features

• Set High and Low limit registers as floats for finer granularity. Currently only setting the MSB as i8 is supported.

Example

This example runs the async configuration using embassy on an stm32.

use embassy_executor::Spawner;
use embassy_stm32::{
    i2c,
    time::Hertz,
};
use embassy_time::{Duration, Timer};
use fmt::{error, info};
use tmp1075::Tmp1075;

#[embassy_executor::main]
async fn main(_spawner: Spawner) {
    let p = embassy_stm32::init(Default::default());

    let mut i2c_conf = i2c::Config::default();
    i2c_conf.timeout = Duration::from_millis(500);
    // Depending on your setup pullups might not be needed
    i2c_conf.scl_pullup = true;
    i2c_conf.sda_pullup = true;
    let mut i2c = i2c::I2c::new(
        p.I2C1,
        p.PB6,
        p.PB7,
        Irqs,
        p.DMA1_CH2,
        p.DMA1_CH3,
        Hertz::khz(400),
        i2c_conf,
    );

    let mut temp_sens = Tmp1075::new(i2c);

    loop {
        match temp_sens.get_temperature().await {
            Ok(temp) => info!("Temperature: {}", temp),
            Err(e) => error!("Error: {:?}", e),
        }

        Timer::after_millis(500).await;
    }
}
