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

The venerable I²C bus has never been more popular. Most modern microcontrollers either have a hardware I²C interface or are capable of bit-banging one in software. Many sensors, AD and DA converters, ...

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 ...

Last week, I covered some of the bitter details of an interesting hack that lets us split up the I²C clock line into multiple outputs with a demultiplexer, effectively giving us “Chip Selects” for ...

The interfacing between the Arduino with I2C is being explained in this project. The interfacing between the Arduino with I2C is being explained in this project. One good thing about using the readily ...

You will probably be familiar with I²C, a serial bus typically used for not-very-fast communication with microcontroller peripherals. It’s likely though that unless you are an I²C wizard you won’t be ...

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your Arduino, or any microcontroller ...

The inter-IC bus, or I2C bus for short, is a two-wire bus designed for connecting simple peripherals that do not require rapid transfer of large amounts of data. In this three-part series we will look ...
