Question

SPI is half duplex. Select one: True False

Answer 1

False.

SPI is a “synchronous” data bus, which means that it uses separate lines for data and a “clock” that keeps both sides in perfect sync. The clock is an oscillating signal that tells the receiver exactly when to sample the bits on the data line.In full duplex mode SPI master device simultaneously transmits data to a slave and receives data from a slave.In SPI, only one side generates the clock signal .The side that generates the clock is called the “master”, and the other side is called the “slave”.
