Many readers will be familiar with interfacing I2C peripherals. A serial line joins a string of individual I2C devices, and each of the devices has its own address on that line.

The circuit shown can be used to interface multiple serial devices to the I2C bus, even if they lack the extended-addressing capability required. Information transfer be-tween ...

An I2C bus scanner can be a helpful first step in debugging an I2C system. Are all the devices that I think should be present actually there and responding?

In I2C mode, two programmable GPIO pins are available for additional peripheral control. Power for attached sensors or peripherals, within limits, can be sourced from the 1-wire bus “making the ...
