I originally wanted to implement a switch, but I recently dragged it so I added some functions. This function is to move the advertising light left and right, but I added an input that can switch a si...
It stands to reason that if I "build current project" for the above project, the corresponding dll should be generated, but it is not. Why? What should I do?...
I designed a circuit using 2812, but no matter how high the input voltage is for AD conversion, the value in the register is always fixed, just like AD is not working! But I have debugged the conversi...
I have a question. In WINCE, I used HalAllocateCommonBuffer to apply for a piece of memory for DMA transmission, and then used memcpy to copy the contents of this memory to another area. Now I find th...
As time goes by, people are increasingly concerned about their own and their families' health. However, existing monitoring devices for individual vital signs have struggled to gain market share du...[Details]
Amidst the wave of intelligent automotive transformation, advanced driver assistance is gradually emerging from cutting-edge technology into the mainstream, becoming a new frontier of industry comp...[Details]
There are basically three causes of spontaneous combustion of electric vehicles: The first is that the battery components are punctured or suffer fatal damage due to a collision accident, and part ...[Details]
With the increasing number of new energy vehicles on the road, the deployment of supporting facilities for these vehicles has accelerated, and new energy vehicles have gradually entered the vision ...[Details]
Charging is a familiar process for new energy vehicles, and as a source of battery energy, charging piles are crucial. New energy vehicle charging can be divided into fast charging and slow chargin...[Details]
During daily operation of an R-type power transformer, the voltage used varies as the equipment being used adjusts. This raises the question: can the transformer change voltage at this point? The a...[Details]
The difference between a series inverter and a parallel inverter is that they use different oscillation circuits. A series inverter connects L, R, and C in series, while a parallel inverter connect...[Details]
The Waveshare ESP32-P4-ETH is a compact ESP32-P4 development board with Ethernet and PoE support. It looks very similar to the Olimex ESP32-P4-DevKit, minus the pUEXT connector. However, we've also...[Details]
Pure electric vehicles have experienced rapid growth in recent years, and many consumers now consider them as a top choice when purchasing a car. But do you know how to choose a satisfactory and sa...[Details]
As my country's industrialization continues to improve, environmental pollution is also facing tremendous pressure. In recent years, national environmental protection policies have become increasin...[Details]
Electronics engineers all know that transient voltage suppression (TVS) diodes are used to protect ports, preventing damage to downstream circuits caused by transient voltage surges. In short, TVS ...[Details]
As in-vehicle audio and video entertainment features become increasingly diverse, the demand for digital transmission of audio and video information is urgent. Traditional protocols such as IEEE 13...[Details]
While aberration theory is a vast subject, a basic understanding of some fundamental concepts can make it easier to understand: spherical aberration, astigmatism, field curvature, and chromatic abe...[Details]
Due to limitations in size, weight, and cost, most continuous-wave radar seekers use single-antenna technology. Insufficient isolation between the transmitter and receiver causes the transmitted si...[Details]
