I got tired of writing low-level register code for sensors, so I made a declarative<br> abstraction layer.</p> <p>Instead of bit-shifting I2C data, you write:</p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> sensor = hardware.attach("I2C", type="BME280") sensor.on_threshold("temperature &gt; 25°C", lambda e: fan.on()) </code></pre> </div> <p>It's called BitBound, available on PyPI. Supports 20+ devices, runs in simulation mode for desktop<br> testing.</p> <p>Happy to share the link if anyone's interested – just comment below!</p> <p>What sensors/actuators would you want supported?</p> python micropython esp32
