I designed a project, which is similar to the previous project. There are LDO33 and LDO120 inside, but the ripple of 3.3 and 1.2 measured by myself is very large. The filter circuits are the same and ...
## Preface: I made an SLCD screen when I was tinkering with GD32L233. I modified it and it ran on AT32F425. The board is actually quite simple. The board is as follows:  used for high-speed and long-distance communications have high requirements for temperature s...[Details]
FCLK clock for CPU HCLK clock is used for AHB bus peripherals PCLK clock is used for APB bus peripherals The S3C2440 has two phase-locked loops (PLLs), One for FCLK, HCLK, PCLK Another one is dedi...[Details]
The failure rate of capacitors in circuits is much higher than that of resistors, and there are many types of failures, making detection difficult. This depends on the approximate size of the capac...[Details]
Power modules are favored by many engineers for their multiple advantages such as high integration, high reliability, and simplified design. However, even if the same power module is used, different ...[Details]
Currently, a large number of embedded systems use microcontrollers, and such applications are being further expanded; however, people have been confused by the reliability of microcontroller system...[Details]
Our surprise at the fact that home appliance companies are making chips may have to start with Gree CEO Dong Mingzhu. In 2018, Ms. Dong, a "top star in the industry", made a bold statement that she...[Details]
White LED energy-saving lamps are now widely used in handheld devices (such as mobile phones) as backlights for color LCD screens and keyboard lights. Colored LED energy-saving lamps are good indic...[Details]
1 Introduction With the rapid development of power technology, synchronous rectification technology is widely used in low-voltage, high-current output DC/DC converters. Under such circumstances, some...[Details]
China's security and risk management (SRM) leaders often feel that their security operations approach is no longer effective. This is because most security operations centers (SOCs) are designed base...[Details]
I believe that everyone is familiar with the method of using IO port to drive segment LED (digital tube), but the method of using IO port to directly drive segment LCD is relatively complicated. I sea...[Details]
Virtual Reality is a whole new type of 3D rendering. This technology has been getting a lot of attention lately. Many people have already experienced VR headsets, and even more will be able to expe...[Details]
Vector network analyzer is an electromagnetic wave energy test instrument that can directly measure active or passive, reversible or irreversible dual-port and single-port complex scattering paramete...[Details]
On January 8, 2024, the Zhangjiakou Municipal Development and Reform Commission announced the Zhangjiakou Municipal Key Construction Project Plan for 2024 (the first batch), which includes 12 energ...[Details]
Preface
Since the issuance of 5G licenses in 2019, after five years of development, my country's 5G has achieved remarkable results in infrastructure construction, user scale, innova...[Details]
