Microcontroller Serial Port Communication Technology The serial interface and communication of microcontrollers are core technologies for data transmission between devices in embedded systems. 1. Basics of Serial Communication 1.Serial vs Parallel Communication Serial communication: Transmits data bit by bit, using fewer pins (14), suitable for long distances and low power consumption scenarios. Parallel communication: Multiple … Read more
Optimizing microcontroller programs usually refers to optimizing program code or execution speed. Optimizing code and optimizing speed are actually a unified contradiction. Generally, optimizing the size of the code will lead to an increase in execution time; if the execution speed of the program is optimized, it usually results in an increase in code size. … Read more
The interrupt system and timer/counter of a microcontroller are core modules for implementing real-time tasks and multitasking. 1. Interrupt System 1. Basic Concepts Interrupt: When a specific event (interrupt source) occurs, the CPU pauses the current task and executes the Interrupt Service Routine (ISR). After completion, it resumes the original task. Function: Improves CPU efficiency, … Read more
