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.
The SPI bus interface is widely used for synchronous data transmission because this interface allows relatively high transmission rates with versatile configurations.
3 sty 2019 · This tutorial describes how to set up and use the on-chip Serial Peripheral Interface (SPI) of the Arduino Board. Most AVR devices come with an on board SPI and can be configured according to requirements.
Serial peripheral interface (SPI) is one of the most widely used interfaces between microcontroller and peripheral ICs such as sensors, ADCs, DACs, shift registers, SRAM, and others.
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.
Serial peripheral interface (SPI) is one of the most widely used interfaces between microcontroller and peripheral ICs such as sensors, ADCs, DACs, shift registers, SRAM, and others.
This technical brief provides information about Serial Peripheral Interface (SPI) on tinyAVR® 0- and 1-series, megaAVR® 0-series, and AVR® DA devices, and intends to familiarize the user with AVR microcontrollers. The document describes the application area, the modes of operation, and the hardware and software requirements of the SPI.
