Recently, the Channel 2 of the power supply of Tektronix's active differential probe stopped working. So I disassembled it to have a look. To satisfy my curiosity. Front: It provides power supply for ...
After modifying the code, there are some redundant networks in ChipWatcher that need to be deleted. After choosing to delete, the entire program will crash. I have tried it many times and it crashes e...
I have just started to learn F2812. The electrical characteristics seem to state that the I/O input should not exceed Vddio. I made a practice board by myself. After I finished it, I found that there ...
At the beginning of the test, the drain of the device under test ( DUT ) is biased by SMU2 and waits for the gate pulse to turn on the transistor to generate the drain current Id .A : Gate voltage pul...
In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]
Recently, the " ZTE
incident"
caused by the Sino-US trade war
has caused heated discussions in the electronics industry. It not only reflects that Chinese companies are lagging behind in the...[Details]
The trade war between China and the United States has become the focus. The United States has begun to play the ban card against Chinese technology companies. The ZTE incident shows that if the ban...[Details]
In Windows environment, the source code is encoded in UTF-8. If the source file created by STM32CubeMX contains Chinese comments, then using STM32CubeMX to regenerate the source code will cause the C...[Details]
Function List and Notes (lower-level driver part) 1. IO port initialization: control IO and communication IO. Control includes power control, reset and low power mode. Communication is the serial po...[Details]
In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]
Recently, the "Smart Photovoltaic Industry Development Action Plan (2018-2020)" jointly issued by six departments has put this concept on the forefront. Photovoltaic smart solutions will become the ne...[Details]
The photovoltaic inverter is the core equipment of the photovoltaic system. Its main function is to convert the direct current generated by the photovoltaic modules into alternating current that meets...[Details]
STM32 uses FSMC to read and write CPLD programs. CPLD is hung on the address line and data line of STM32. CPLD is regarded as an off-chip RAM for reading and writing. On the board I made, CPLD is hun...[Details]
On Sunday, the South Australian government unveiled plans to build the world's largest virtual power plant, which will connect at least 50,000 homes over four years and have a capacity ...[Details]
WPG Holdings announced that its subsidiary Youshang has launched a wireless smoke alarm solution based on STM and Semtech . With the development of the national economy and the enhancement of...[Details]

The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[Details]
The STM32 watchdog has two WWDG and IWDG. The biggest difference between the two is that IWDG has only one lower limit for feeding, while WWDG, as the name implies, must be fed within a range to ensu...[Details]
The frequency calculation formula of the PWM wave generated by the output comparison mode of the timer is: 72M/((2*(arr+1))*(psc+1) ) For example, if you set: PWM_Init(1000-1,72-1); (PWM_Init(arr,psc...[Details]
