An Arduino library for I²C device operations. This is an abstraction class which can be used for all I²C devices to manage access at the register level. In addition to the device abstraction, it ...

This Arduino Mega/Due sketches use 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.

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

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 ...

The Challenger RP2040 WiFi is a microcontroller board from iLabs. It combines a Raspberry Pi RP2040 microcontroller with an ESP8285 for Wi-Fi connectivity. The board has two LEDs, one of which is a ...
