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.
This document describes the serial peripheral interface (SPI) in the TMS320C5515/14/05/04/VC05/VC04 Digital Signal Processor (DSP). The SPI is a high-speedsynchronous serial input/output port that allows a serial bit stream of programmed length (1 to 32 bits) to be shifted into and out of the device at a programmed bit-transferrate. The SPI
The SPI is a high-speed synchronous serial input/output port that allows a serial bit stream of programmed length (2 to 16 bits) to be shifted into and out of the device at a programmed bit-transfer rate. The SPI is normally used for communication between the device and external peripherals.
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.
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 simplified SPI block diagram shows its basic control mechanisms and functions. There are four I/O signals associated with the SPI peripheral. All of the data passes through receive and transmit buffers via their specific interfaces. The control block features are enabled or disabled depending on the configuration.
The SPI bus interface is widely used for synchronous data transmission because this interface allows relatively high transmission rates with versatile configurations.
