Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Who Won and Lost in Trump’s Tax Bill Scientists tracking ‘interstellar’ object that has come ...

This is why I read Hackaday every day. I2C is great in that it lets you connect up multiple devices to a pair of wires using a very bus architecture.

The circuit shown can be used to interface multiple serial devices to the I 2 C bus, even if they lack the extended-addressing capability required. Information transfer be-tween I 2 C devices ...

We’ve covered them before, but in short, address translators let you avoid I2C address conflicts while using multiple devices that share the same address.

Its maximum frequency is 360 kHz, vs. 90 kHz in the PCA8584. The new product also has an internal clock instead of an external one, and a 50-MHz interface. The PCA9564 is optimized for interfacing ...
