Serial Peripheral Interface (SPI) is one of the most widely used interface between microcontroller and peripheral ICs such as sensors, ADCs, DACs, Shift register, SRAM etc. This article provides a brief description of the SPI interface followed by introducing Analog Devices’ SPI enabled switches and muxes and … See more 4-wire SPI devices have four signals: 1. Clock (SPI CLK, SCLK) 2. Chip select (CS) 3. main out, subnode in (MOSI) 4. main in, subnode out (MISO) The device that generates the clock … See more To begin SPI communication, the main must send the clock signal and select the subnode by enabling the CS signal. Usually chip select is an active low signal; hence, the main must send a logic 0 on this signal to select the subnode. … See more Multiple subnodes can be used with a single SPI main. The subnodes can be connected in regular mode or daisy-chain mode. See more In SPI, the main can select the clock polarity and clock phase. The CPOL bit sets the polarity of the clock signal during the idle state. The idle state is defined as the period when CS is high and transitioning to low at … See more WebApr 13, 2024 · At Example Design tab, Select Design and enable Generate 3-wire SPI module then Generate Example Design.

Serial Peripheral Interface - Wikipedia

Spy-Bi-Wire is a serialised JTAG protocol developed by Texas Instruments for their MSP430 micro controllers. In this protocol only two connections are used instead of the usual four pins for the general JTAG interface. The two connections are a bidirectional data output, and a clock. The clocking signal is split into a period of three clock pulses, for each clock pulse the TDI, TDO and TMS signals are p… WebJan 29, 2016 · You could use another serial protocol like one wire or UART (if you send commands only one way).
