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.
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 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.
MSP430’s peripheral communication modules helps you to reduce CPU loading. Be aware about the initialization sequence of USART and USCI modules (follow the recommendations of the User’s Guides) Detailed module descriptions can be found in the MSP430 User’s Guides.
The SPI bus interface is widely used for synchronous data transmission because this interface allows relatively high transmission rates with versatile configurations.
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.
