What are serial peripheral devices?

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.

What is the meaning of peripheral interface?

In a computer, a serial peripheral interface (SPI) is an interface that enables the serial (one bit at a time) exchange of data between two devices, one called a master and the other called a slave . It is also possible to connect two microprocessors by means of SPI. The term was originally coined by Motorola.

What is MOSI and MISO?

MOSI and MISO are the data lines. MOSI transmits data from the master to the slave and MISO transmits data from the slave to the master.

What is Serial Peripheral Interface SPI Mcq?

Explanation: The serial peripheral interface allows the full duplex synchronous communication between the master and the slave devices. MC68HC05 developed by Motorola uses SPI for interfacing the peripheral devices.

How memory chips and I O devices are interfaced to a microprocessor?

The corresponding memory chip or I/O device is selected by a decoding circuit. Memory requires some signals to read from and write to registers and microprocessor transmits some signals for reading or writing data. The interfacing process includes matching the memory requirements with the microprocessor signals.

What is Group A in PPI 8255?

The 8255 gives a CPU or digital system access to programmable parallel I/O. Port C can be used as an 8-bit input/output port or as two 4-bit input/output ports or to produce handshake signals for ports A and B. The three ports are further grouped as follows: Group A consisting of port A and upper part of port C.

Does miso connect to MOSI?

MOSI on a master connects to MOSI on a slave. MISO on a master connects to MISO on a slave. Slave Select has the same functionality as chip select and is used instead of an addressing concept.

What is SPI API?

From Wikipedia, the free encyclopedia. Service provider interface (SPI) is an API intended to be implemented or extended by a third party. It can be used to enable framework extension and replaceable components.

Which are peripheral devices use serial interface?

The Serial Peripheral Interface (SPI) module is a synchronous serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be Serial EEPROMs, shift registers, display drivers, A/D converters , etc.

What is the most common interface for peripheral devices?

PATA Serial Firewire USB Explanation USB is the most common interface for peripheral devices, such as printers, keyboards, and mice. Firewire is a common interface for digital video cameras and recorders, hard drives, and network adapters. Serial interfaces are common for modems, older printers, and networking devices.

What is a parallel peripheral device interface?

The Parallel Peripheral Interface (PPI) is a peripheral found on the Blackfin embedded processor. The PPI is a half-duplex, bi-directional port that is designed to connect directly to LCDs, CMOS sensors, CCDs, video encoders (video DACs), video decoders (video ADCs) or any generic high speed, parallel device.. The width of the PPI is programmable and can be set between 8 and 16 bits in 1-bit

What is Intelligent Peripheral Interface?

IPI (Intelligent Peripheral Interface) is a high-bandwidth interface between a computer and a hard disk or a tape device. Devices using IPI can transfer data between the hard drive and RAM in the range between 3 and 25 megabytes per second.
