Thank you for having you +EEWORLD
Thank you eeworld for your company over the past year. It is great to have eeworld accompany me along the way. We have gained a lot of knowledge, broadened our horizo...
How should I interpret the circuit here? The gate and drain are shorted together. Since the I/O port of the microcontroller can only withstand 0 to 5 V, the output signal needs to be pulled to12 V so ...
I use a brushless sensorless motor board. The motor starts to rotate fine at first, but after accelerating to a certain degree, the motor vibrates violently and the speed cannot be increased. What is ...
In 430, one clock cycle = the inverse of the MCLK crystal oscillator. If MCLK is 8M, then one clock cycle is 1/8us;one machine cycle = one clock cycle, that is, each action of 430 can complete a basic...
As shown in the figure below, the terminal block is a double-layer pluggable terminal block
What does the number of positions in the red box in the picture mean?
It looks like there are 20 interfaces ...
Cisco Systems, a Silicon Valley-based company that makes the Internet possible, knows better than anyone how a company can use network-based resources to improve operational performance. Now, with ...[Details]
In Keil, printf sends data to the serial port by default. Therefore, if you use this function, you must initialize the serial port first, otherwise it may cause a crash. In addition, TI should be set ...[Details]
Recently, the medium-power 36KW photovoltaic grid-connected inverter independently developed and manufactured by Shouhang New Energy was officially launched on the market, which once again refreshe...[Details]
Ⅰ. Write in front The content of this article is just as the title "Configuration", but the title contains more content, so I plan to divide it into two articles: Configuration (I) and Configuration ...[Details]
With the application of computers, in order to reduce hardware equipment, a programmable gain amplifier (PGA) can be used. It is a very versatile amplifier, and its amplification factor can be control...[Details]
The program in the YL-69 data sheet includes the test program for the 51 microcontroller and Arduino. I used the program for the 51. Let me talk about my module first. It is a four-wire system. If yo...[Details]
When the stepper motor works normally, it moves one step angle for each control pulse it receives, that is, it moves forward one step. If the control pulses are continuously input, the motor will r...[Details]
1. Introduction to Wired Communication Chips
With the rapid development of information, computing and chip technology, the demand for external information interaction is growing, the number of...[Details]
In the United States and other countries, light-emitting diodes (LEDs) are being used in airport lighting. The purpose of this comprehensive study is to provide data on the performance of LED airpo...[Details]
The comparator setting of STM32F051 is relatively simple, where the internal reference voltage VREFINT can be used as the comparison object. Here, it is easy to take it for granted that VREFINT is ...[Details]
Preface: I didn't need the serial port originally, but recently when I was reading the sensor data, the data was wrong. My senior recommended that I use the serial port to check what the data was, so...[Details]
introduction
LED (Light Emitting Diode) is a new type of competitive solid light source in the 21st century. Compared with traditional light sources, it has the advantages of small si...[Details]
In high-frequency system measurement and application, it is often necessary to use multi-channel coherent signals. Generally, we can use devices such as power dividers, phase shifters, amplifier...[Details]
I will try to explain these two questions clearly in an article today.
Let me first state a conclusion: the former problem is the basis of the latter problem. Without solving the former proble...[Details]
In 2024, the growth of the AR industry is significantly faster than that of VR devices, and shipments have also increased. The differences between the AR and VR industries reflect that consumers' p...[Details]
