History of Atmel Automotive Electronics : https://training.eeworld.com.cn/course/252? Rob Valiton, senior vice president of Atmel's automotive products division, discusses Atmel's history in automotiv...
Use a mobile power bank to power the board, and then use the LED on the board to check the remaining power. To achieve this function, can an ADC module be used to determine the difference in input vol...
Light-controlled street light The working principle of the circuit of the device is shown in Figure 12. During the day, when strong light shines on the photoresistor RG, the internal resistance of RG ...
The parameters of the components in the figure are not given, just to see if the principle is feasible. I plan to make an electronic piano, using a single-chip microcomputer to generate SPWM waves to ...
In recent years, as energy consumption and environmental protection issues have attracted people's attention, my country's solar photovoltaic power generation industry has shown a rapid development...[Details]

As photovoltaic power stations come into people's view, people are paying more and more attention to them. Recently, some netizens asked me how to match the inverter and components of photovoltaic ...[Details]
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
Using the WWDG of STM32F030, it is found that the MCU will not be reset under STOP, just like the sleep mode of STM8S. Paste the watchdog code: /******************************************************...[Details]
At the beginning, I used the stdlib library. Recently, I found that the cube library is more and more widely used, so I started to use the cube library to complete the ADC multi-channel acquisition e...[Details]
STM32 has 2 watchdogs: independent watchdog and window watchdog. Independent watchdog IWDG: A system fault detector that is independent of the system and is not affected by the system because it has ...[Details]
The calculation formula of the watchdog feeding time (watchdog overflow time) is: Tout=((4*2^prer)*rlr)/40 Tout is the watchdog overflow time (in ms), prer is the watchdog clock prescaler value (...[Details]
The storage media corresponding to the three boot modes of STM32 are built-in to the chip, they are: 1. User Flash = Flash built into the chip 2.SRAM = RAM area built into the chip, which is the m...[Details]
Internal channels of ADC: In addition to using external channels to collect external analog voltage signals, the ADC of STM32 also has two internal channels 16 and 17. Channel 16 is connected to ...[Details]
Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[Details]
