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 ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

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, ...

I2C_SCANNER is a class to build an I2C scanner, either minimal or more complex. The class provides different functions to analyse the connectivity of devices on the I2C bus. There are functions to ...

Inexpensive OLED displays with I2C interfaces abound, but there is a catch: they tend to be stuck on I2C address 0x3C. Some have a jumper or solder pads to select an alternate (usually 0x3D), but they ...

The I2C protocol, which stands for Inter-Integrated Circuit, is a serial communication protocol that uses two wires: a clock line (SCL) and a data line (SDA). The I2C protocol allows multiple devices ...

For several microcontroller projects, the integration of a minuscule display panel can be handy to show relevant information. For example, information gathered by an external sensor module. Here we ...

The Musical Instrument Digital Interface has a great acronym that is both nice to say and cleanly descriptive. The standard for talking to musical instruments relies on a serial signal at 31250 bps, ...

– Small size: As small as a thumb(20×17.5mm) for wearable devices and small projects. – Multiple development interfaces: 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, ...
