This Arduino Mega sketch uses direct port read and bit manipulations to sniff an i2c bus running at up to 100 kHz. The analysis of the i2c communication is displayed on the Serial monitor. Connect SDA ...

This library is written to use the NXP PCF85263 RTC. The functionality implemented is just basic date time retrieval. The device can run in a stop-watch mode. The range goes up to 999 999 hours, which ...

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 helpful ...

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many of those pitfalls, ...

Serial Kickstarter campaign creators SwitchDoc Labs have now launched their fourth campaign via the crowdfunding website to raise the required funds they need to take their new Raspberry Pi and ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...
