Description: The Microcontroller Interface Protocol refers to the set of rules and conventions that determine how a microcontroller communicates with other devices in an embedded system. This protocol is essential to ensure that data is transmitted effectively and accurately between the microcontroller and peripherals such as sensors, actuators, and other microcontrollers. Key features of this protocol include the definition of data formats, synchronization methods, and error management during communication. The relevance of the Microcontroller Interface Protocol lies in its ability to facilitate interoperability among different system components, enabling the creation of more complex and functional applications. Without a well-defined protocol, communication between devices could become chaotic, affecting the overall performance and reliability of the embedded system.
