Experience One: Using “Software Traps + Program ID” to Handle PC Pointer Jumps When the CPU is subjected to external interference, sometimes the PC pointer may jump to another segment of the program or to a blank segment. In fact, if the PC pointer jumps to a blank segment, it can be handled relatively easily. … Read more
[Introduction] After writing so many microcontroller programs, you see the watchdog every day. Are you taking care of your watchdog properly? Just keep feeding it, and as long as it doesn’t bark, everything is fine, right? Is it really that simple? In fact, it may not be as straightforward as you think… What is a … Read more

In the field of digital circuits, the reset function of microcontrollers is a crucial step to ensure their normal startup and operation. The reset function mainly resets the internal state of the microcontroller to its initial state, preventing issues such as chaos, runaway, or freezing during program execution, making the system ready to accept and … Read more
