The moderator KDY is very careful and packed it very carefully. The board is also beautiful. Thanks to KDY and EEWORLD for launching this great event. Haha, I'm going to play with FPGA these days.:)...
Can the program of the STC89C52RC microcontroller be copied? The program in the original circuit is a soft starter. The newly purchased chip has no display on the machine, but I still can't download i...
I'm working on the USB communication of f320 recently. Recently, a problem has occurred. When the development board is connected to the computer via USB alone, the USBXpress device can be displayed in...

I guess there should be quite a few college students participating in this competition. I just finished the evaluation today. I don't know how everyone's competition results are, come in and show your...
If you have used zlg/fs, please come in. When I use zlg/fs and zlg/sd drivers to write to the SD card, why is the data not written to the file? It just creates a file. I still use the AllCacheWriteBac...
In recent years, the market for mobile/portable devices such as smartphones and laptops has continued to grow rapidly. While these products continue to integrate more new features to enhance the ...[Details]
1. Introduction
Light control circuit plays a vital role in urban street lamps or corridor lighting. With light control circuit, the lights can be automatically turned on and off according to ...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
At very low temperatures, certain metals and alloys lose their resistance to electric

The launch of Shenzhou IX is imminent, and Tiangong is welcoming visitors again. Yesterday, Professor Fu Qiang, Vice President of the Institute of Science and Industrial Technology of Harbin Instit...[Details]
Leakage current is generated by parasitic resistance paths between the measurement circuit and a nearby voltage source. This current can significantly reduce the accuracy of low current measurement...[Details]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
Stepper motors, also called steppers, use the principles of electromagnetism to convert electrical energy into mechanical energy and have been used since the 1920s. With the increasing popularity o...[Details]
As we all know, the manufacturing of modern automobiles is divided into four major processes: stamping, welding, painting and assembly, and the powertrain constitutes five inseparable production pr...[Details]
1 Causes of problems with electric vehicle batteries
1.1 Caused by the battery itself
Why do we say that? In the previous issue, we learned about the working princi...[Details]
Lithium iron phosphate batteries are used as lithium-ion secondary batteries. Their main application is now in power batteries, which have great advantages over NI-H and Ni-Cd batteries.
