Advanced SPI Communication Techniques: From Four-Wire to Quad SPI, Daisy Chain Solutions to Double Your Project Speed!

1. Independent Chip Select (Standard Multi-Slave Mode) Solution Description: Each slave device is assigned an independent SS (chip select) line, and the master device activates the target slave by pulling down the corresponding SS line.Advantages: Each slave is independently controlled, and communication does not interfere with each other. Supports full-duplex high-speed transmission.Disadvantages: The number of … Read more

Understanding the SPI Bus Interface

The Serial Peripheral Interface (SPI) is one of the most widely used interfaces between microcontrollers and peripheral ICs (such as sensors, ADCs, DACs, shift registers, SRAM, etc.). SPI is a synchronous, full-duplex, master-slave interface. Data from the master or slave is synchronized on the rising or falling edge of the clock. Both the master and … Read more

Fundamentals of Four-Line SPI Communication and Daisy Chain Configuration

Formatting | Last BugThe main content shared today is derived from ADI’s SPI knowledge study. SPI is one of the most commonly used communication methods in embedded development. However, most embedded software engineers often focus more on upper-layer software development and tend to overlook some underlying signal formats. When communication issues arise, it can be … Read more
