The SPI bus is<span><span>a synchronous, bidirectional, full-duplex 4-wire serial interface bus</span></span>, originally proposed by Motorola. The SPI system consists of a “single master device + multiple slave devices.” It is important to note that as long as only one master device is active at any given time, multiple SPI master devices can exist in the … Read more
1. What is SPI? SPI stands for Serial Peripheral Interface, a synchronous serial interface technology introduced by Motorola. It is a <span>high-speed</span>, <span>full-duplex</span>, and <span>synchronous</span> communication bus. 2. Advantages of SPI Supports full-duplex communication, simple data transmission rate. 3. Disadvantages There is no specified flow control and no acknowledgment mechanism to confirm whether data has … Read more
UART, I2C, and SPI are the three most commonly used communication protocols in microcontroller systems. In this lesson, we will learn about the remaining SPI communication protocol. SPI stands for Serial Peripheral Interface. As the name suggests, it is a serial interface for peripheral devices. SPI is a high-speed, full-duplex, synchronous communication bus that typically … Read more
