1, first of all, the hardware is abnormal, the power supply is unstable, and the reset pin fluctuates. Second, the watchdog reset and the code did not feed the dog in time. Finally, software exception, overflow.
2, in the power side of the control board into an EMI power filter, this thing anti-interference that is not to say. They're everywhere and they're cheap.
3, LCD TV automatic reset may be caused by a variety of reasons, such as overheating, power problems, signal source problems and so on. Here are some common onesSolution: Check whether the power cord and plug are stable and ensure that the power supply is normal. Check that the TV is not overheating.
4. Power off the battery. Electronic thermometer is composed of temperature sensor, liquid crystal display, button battery, application-specific integrated circuit and other electronic components. The electronic hygrograph keeps resetting itself because the battery is out of power. The electronic temperature and humidity recorder is a series of data loggers specially designed for ultra-low power consumption and ultra-long time temperature data recording.
5, water heaters often reset there are many possible reasons. Here are a few things that can cause a water heater to reset. Water heater passIt may not match STM32 in performance. Although both are 32-bit microcontrollers, the STC32 uses a lower-performance processor core, while the STM32 uses a high-performance ARMCortex-M series core, so there is a certain gap in actual performance.
Yes, stm32 popular library development. The startup code needs to be noted that the STM32 time system should be mastered well, the code does not have errors, but the system does not work, may be the startup code setting error. STM official website many resources, directly with his official Demo development can be.
NXP, Atmel, DSP. The downside, is it a little more expensive? Many microcontroller performance is superior to stm32. However, stm32 has more users and more data, and the development difficulty is low, which is the advantage of stm32.
No. stm32 program and 51 MCU is not universal. There are three main reasons for this: STM32 is 32-bit, while 51 is 8-bit, so the definition of program variables is different. Their internal functional structure is completely different, so the program is naturally not universal.

3, can. 3kac chip can be used instead of 3kal, and the two models can also be used instead of each other. Now many domestic brands including Huada, Yatli, Lingdong Micro, Qin Hengwei, Hangshun 3kac chip can replace 3kal chip, which has excellent performance in the application of many subdivisions.
4. No. According to the official website of the China Securities Regulatory Commission, Hangshun chip is an unlisted company, and there is no active trading market for its equity. Listed companies, are shares haveThe term "limited company" refers to a company limited by shares whose stocks have been approved by The State Council or the securities regulatory department authorized by The State Council to be listed and traded on a stock exchange.
5, although you can give the baby to eat stamen tablets, white water tablets for babies with poor immunity and easy to catch a cold, have a very good protective effect, but also can effectively prevent repeated respiratory infections. When giving your baby a litmus tablet, you should pay attention to the specific dosage.
6, first of all, the hardware is abnormal, the power supply is unstable, and the reset pin fluctuates. Second, the watchdog reset and the code did not feed the dog in time. Finally, the software is abnormal, overflow.
