A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a ...

[Wayne] wrote in to share an item he just finished working on, an I2C GPS shield for the Arduino. While other GPS solutions have existed for quite some time, his caught our eye due to its feature l… ...

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 ...

Actually, PCF8574 and PCF8574A are identical, except for the different fixed portion of the slave address. The three hardware address pins allow eight of each device to be on the same I 2 C-bus, so ...

NXP Semiconductors has introduced its first no-offset I2C-bus buffers, which are designed to isolate capacitance and so allow interface with other bus buffers. Significantly, the bus buffers use the ...
