SPI data rates are commonly in the range of 1 to 70 MHz and byte lengths can range from 8- and 12-bits to multiples of these values. Data transfers always consist of a data exchange. While the master ...

Interfacing with the outside world is a fairly common microcontroller task. Outside of certain use cases microcontrollers are arguably primarily useful because of how easily they can interface with ...

The serial peripheral interface (SPI) bus is a synchronous, full-duplex, serial data link commonly used for the short-distance data exchange between a master device, such as a microcontroller unit ...

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 ...

There comes a time when you need to wire up three, four, or more identical i2c devices to a common microcontroller. Maybe you’re thinking about driving 128 seven-segment displays with eight of those ...
