Thank you! Just some minor nitpicks.
use std::atomic_bool in example better sign-extension for both pressure and temperature support blocking usage on smol mcus remove deprecated nested layers replace buffer accesses with something more modern

Driver for the Bosch Sensortec BMP581 pressure and temperature sensor.
Example code outputs:
I am actually on 530 m, nearest weather station reports:
963 hPa at 515 m corresponds to 961 hPa on 530 m, which is basically what the sensor is reading. Absolute pressure accuracy is specified with ±0.5 hPa at 25 °C and ±1.0 hPa (max) over 0–65 °C. Unfortunately my PCB actually gets 40 °C hot, so that reading is correct as well.
Tested the sensor at different output data rates and in both polling and interrupt modes. Could test only in I2C mode and only on STM32 because that's how my board is wired up.
