What is SPI?
Serial Peripheral Interface: synchronous serial communication in which data is exchanged in both directions on a master-driven clock, with devices selected by chip-select lines. Used for fast parts.
Field: Embedded Systems & Firmware
SPI in the explanations
SPI is synchronous communication in which, on the clock driven by the master, data flows simultaneously on a master-to-slave line and a slave-to-master line.
What is a characteristic of SPI communication?In SPI, the master drives the clock on SCLK, sends data on MOSI (master out, slave in) and simultaneously receives data on MISO (master in, slave out).
Which set of four signals is generally used by SPI?SPI has four modes formed by combining the idle level of the clock (CPOL) and which clock edge samples the data (CPHA).
