There are many sensitive components inside a microcontroller, and these components are very sensitive to external factors. If they are affected by electromagnetic interference, it can easily lead to the system not operating normally and stably. Therefore, electronic engineers must take reasonable measures to enhance the anti-interference performance of sensitive components. So how should this … Read more

In the world of microcontrollers, registers play a crucial role. They are not only key components for data storage and processing but also the core of various operations performed by the microcontroller. Based on type, they can be divided into program memory, data memory, and special function registers. 1. Program Memory Program memory, as the … Read more
Power Supply: If the microcontroller is having issues, first check the power supply. There may be a problem with the power supply. Use a multimeter to check the power supply voltage of the microcontroller; it is best to use an oscilloscope to capture the voltage waveform because the voltage may be unstable (for example, voltage … Read more

Microcontroller Instruction Execution Let’s consider a question: when we write an instruction into the microcontroller using a programmer, and then take the microcontroller out, it can execute that instruction. So this instruction must be stored somewhere in the microcontroller, and this place can retain the instruction even after the microcontroller loses power. What is this … Read more
Introduction Microcontrollers are quite “low-level” and “hardware” components, lacking complex data structures and intricate programming algorithms. We only need to understand and program from the perspective of how the microcontroller executes. For the average person, there is no need to delve deeply into the subject, as most of us are merely users of microcontrollers, not … Read more
