SPI Interface Explanation and Principles

01 【Introduction】 SPI: Serial Peripheral Interface, is a synchronous serial interface for device communication. SPI was developed by Motorola around 1985 and is suitable for short-distance, device-to-device communication. Since then, this interface has become a de facto standard adopted by many semiconductor manufacturers, especially microcontrollers (MCUs) and microprocessors (MPUs). 02 【SPI Interface】 The SPI bus … Read more
