Here is a brief overview of I2C, SPI, and UART communication:
I2C (Inter-Integrated Circuit) is a synchronous, multi-master, multi-slave bus standard that is commonly used for connecting low-speed devices within embedded systems. It is a simple and widely used protocol that is well-suited for applications that require low power consumption and a small number of devices.
SPI (Serial Peripheral Interface) is a synchronous serial bus standard that is commonly used for connecting high-speed devices within embedded systems. It is a more complex protocol than I2C, but it can achieve higher data rates. SPI is often used for connecting devices such as sensors, microcontrollers, and memory chips.
UART (Universal Asynchronous Receiver/Transmitter) is an asynchronous serial communication protocol that is used to transmit data between two devices. It is the simplest of the three protocols, but it is also the slowest. UART is often used for connecting devices such as modems and microcontrollers to a computer.
