When an air quality display project needed a display, [Inderpreet] looked into small character-based LCDs. [Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than shy away, ...

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 ...

In embedded systems, SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit) protocols are both used for communication between microcontrollers and other integrated circuits. Which of ...

The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a ...

In the world of slower communications, the most popular protocols by far are I²C (for ‘Inter-Integrated Circuit’ protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well suited ...
