Enum SpiMode

Defines how data is synchronized between devices on a SPI bus. Clock Polarity (CPOL) determines if clock signal is low or high when in idle state. Clock Phase (CPHA) determines when data is sampled relative to the clock signal.

Fields

Name Description
Mode0

CPOL 0, CPHA 0. Polarity is idled low and data is sampled on rising edge of the clock signal.
Mode1

CPOL 0, CPHA 1. Polarity is idled low and data is sampled on falling edge of the clock signal.
Mode2

CPOL 1, CPHA 0. Polarity is idled high and data is sampled on falling edge of the clock signal.
Mode3

CPOL 1, CPHA 1. Polarity is idled high and data is sampled on rising edge of the clock signal.
