When STM32 writes Winbond w25X16, it reads correctly but cannot write into it. You can use your own program to read the string written by the routine, but your own program cannot write into it. /*Stri...
A year has passed in the blink of an eye, and I have to sigh that time is like flowing water, and time is like a white horse passing by. I have to wonder how people feel about the time that has passed...
Hey guys, has anyone used PIC microcontroller to code the digital tube display program of HC-SR04 ultrasonic module? I need help, please give me some advice....
I am currently working on connecting a wireless module to a router to form a local area network, so that the two modules can communicate with each other through the router as a bridge. The module is s...
Today's portable medical devices allow patients to diagnose and treat themselves, move around freely, and even use the devices when they are out and about. To achieve the "easy to carry" feature, po...[Details]

Metal halide lamp (MHL) as a green lighting source has been widely used in the field of indoor and outdoor lighting. However, when using this green lighting source, the matc...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]
introduction
When we run or ride a bicycle, the vibration of our arms often makes the images displayed on the electronic devices in our hands look blurry. Long-term viewing (such as watchi...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
introduction
In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]
1 Introduction
Generally, when transmitting information over short distances through electrical signals, baseband signals can be directly transmitted. However, over long distances, baseban...[Details]
Two doctors in Chennai, a major technology city in southern India, have developed a generator installed in the high heels. The generator generates weak electricity through the vibration and pressure o...[Details]
