1. Introduction to SPI SPI, which stands for Serial Peripheral Interface, is a synchronous serial communication protocol originally defined by Motorola for its MC68HCXX series processors. The SPI interface is primarily used for communication between EEPROMs, FLASH memory, real-time clocks, ADCs, as well as digital signal processors and digital signal decoders. SPI is a high-speed, … Read more
