In our common sense, the word technology often has two definitions. The first is the technology sealed in the laboratory. They are like flowers on the mountain top. Only a few people on the mountai...[Details]

In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]

 I recently upgraded MDK to V5.25 and found that there are many libraries in the Managing Run-Time Environment. Compared with the past, it is much better, from the bottom-level driver to the upper-le...[Details]

The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]

We have come a long way from the 2G era, and now 5G is about to be commercialized. Suddenly, we realize that time has passed quickly, but technology has never stopped. The activation of 5G heralds ...[Details]

Recently, there was news that the US government asked Google to shut down the Android operating system for ZTE phones. After that, some people even imagined what the consequences would be if Intern...[Details]

introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[Details]

I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]

Overview Lightning is a strong discharge phenomenon that occurs between thunderstorm clouds and between thunderstorm clouds and the earth due to severe convective weather. Lightning is gen...[Details]

1. FSMC Brief           FSMC, the Flexible Static Storage Controller, is capable of interfacing with synchronous or asynchronous memories and 16-bit PC memory cards. The FSMC interface of STM32 s...[Details]

In recent years, the application of high-brightness LED has developed rapidly, especially in signboards and traffic lights. For automotive applications, LED is also very attractive. Long life, shock ...[Details]

STM32 Watchdog Summary I have been adjusting the development board of Atom Brother for more than a year, and it is basically usable, but I still don't understand the working mechanism of some basi...[Details]

Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]

The photovoltaic industry has become a new business card for China to the world. It not only represents China's leading technology, but also constantly breaks various records with its development spee...[Details]

A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
