Serial Peripheral Interface (SPI) is an interface bus commonly used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data lines, along with a select line to choose the device you wish to talk to.

This article provides a brief description of the SPI interface followed by an introduction to Analog Devices’ SPI enabled switches and muxes, and how they help reduce the number of digital GPIOs in system board design. SPI is a synchronous, full duplex main-subnode-based interface.
The SPI bus interface is widely used for synchronous data transmission because this interface allows relatively high transmission rates with versatile configurations.
The most common serial interface used in precision data converters is a standard known as Serial Peripheral Interface abbreviated as SPI. There are two control lines for SPI. The controller, usually a microcontroller or DSP, controls a peripheral select and the serial clock used for data synchronization.
The SPI is a high-speedsynchronous serial input/output port that allows a serial bit stream of programmed length (1 to 16 bits) to be shifted into and out of the device at a programmed bit-transferrate.
20 lut 2022 · I have included a detailed specification, pin diagram, and code for SPI communication between two Arduino boards. I have also included Arduino SPI read example with the RFID-RC522 reader. After this article, you will learn how to use the SPI protocol and read/write data via the SPI protocol.
18 gru 2018 · Arduino SPI Communication Circuit Diagram. The below circuit diagram shows how to use SPI on Arduino UNO, but you can follow the same procedure for Arduino Mega SPI Communication or Arduino nano SPI communication. Almost everything will remain the same except for the pin number.
