Understanding SPI communication
SPI is a synchronous serial communication protocol widely used for connecting microcontrollers or other digital devices with peripheral devices. It provides a straightforward and efficient means of data transfer, making it suitable for applications that require high-speed and full- duplex communication.
Like the I2C communication protocol, the SPI protocol uses a master-slave architecture, where one device acts as a master, controlling the communication, and one or more devices act as slaves, responding to commands from the master.
In this section, we will explore the following topics related to the SPI communication and ESP32:
- How SPI communication works
- SPI communication example using ESP32
- Sensors or devices that use SPI communication
By the end of this section, you will be able to understand what the SPI communication protocol is, how it works, how we can use it in ESP32-based projects, and some common peripherals in...
