I opened the PWM stream driver in the initialization of the dialog application hPWMFile=CreateFile(TEXT("PWM1:"),GENERIC_READ|GENERIC_WRITE,0,NULL,OPEN_EXISTING,0,0); BYTE prescale1[2]={0,97}; BYTE di...
First of all, I have to confess that my title is quite passionate because I received the M4 development board - Hanker this morning :hug:Quickly disassemble and look at the board directly. The board i...
When I was making an amplifier, I found that there was high-frequency interference when the amplification factor was large, but I couldn't filter it out with a low-pass filter. Because the bandwidth r...
statement:This USBISP is made based on an open source design from a German on the Internet ( http://www.ullihome.de/index.php/USBAVR-ISP ).
I only made a few changes to the hardware. I have made more ...
With the promotion of the construction of intelligent communities in the country, anti-theft systems have become essential equipment for intelligent communities. Especially in recent years, the urg...[Details]

1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
1 Introduction
Water resources are the basic conditions for human survival and the lifeline of economic development. The reality shows that due to the global shortage of water resources and th...[Details]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
At present, a large number of cooling tower fans, speed fans and special fans are in use in petroleum, chemical, pharmaceutical, metallurgical and other enterprises. Some fans have no monitoring in...[Details]
The DisplayPort interface standard is approved by the Video Electronics Standards Association (VESA) to provide an open, scalable standard for the entire industry. The development of DisplayPort ca...[Details]
The future energy storage hotspot is not coal or iron ore, but lithium. This lightest metal in nature may be the heaviest resource in the future energy landscape. China launched an ambitious electr...[Details]
Introduction
my country's rapid economic growth is mainly due to the development of manufacturing and the acceleration of urbanization. However, urbanization cannot be achieved at the expense ...[Details]
The principles to be followed are as follows:
