Read MoreUART – The Universal Asynchronous Receiver-Transmitter
UART is a full duplex serial interface. It enables two devices to communicate over just three wires and supports variable speeds. UART Characteristics Like the name suggests, UART is an asynchronous interface. Unlike SPI or I2C there is no need for a dedicated clock. The two devices just need to use the same transmission speed.…
Read MoreI2C – The Inter-Integrated Circuit Bus
The I2C bus is very commonly used in the embedded realm. We explain how it works and how to set it up on the Raspberry Pi with an example. I2C Characteristics The Inter-Integrated Circuit Bus is a synchronous serial communication bus. Philips Semiconductors was responsible for the invention in 1982 but the interface quickly gained…
Read MoreSPI – The Serial Peripheral Interface
SPI means Serial Peripheral Interface. With SPI you can exchange data blazingly fast between two devices. And you only need four wires. SPI Characteristics The serial peripheral interface is a synchronous communication interface for short distances. Synchronous means that the data is sent in form of blocks or frames and the the two devices are…
