Serial Peripheral Interface is a de facto standard for synchronous serial communication, used primarily in embedded systems for short-distance wired communication between integrated circuits.
I2C
…to control a network of device chips with just two general-purpose I/O pins. Many other bus technologies used in similar applications, such as Serial Peripheral Interface Bus (SPI), require more pins and signals to connect multiple devices. System Management Bus (SMBus), defined by Intel and Duracell in 1994, is a subset of…
