With the wide and in-depth application of computers, the technical requirements for the bridge between the digital world and the physical world - A/D converter, that is, the analog front end, are gett...
I recently encountered a very troublesome problem. I used the AT89C2051 microcontroller to write a small program using C language to perform simple IO port output control operations (output 0, 1). It ...
I have been exploring the design in recent days. . . At first, I planned to use an op amp and a current transformer to build a sampling circuit by myself, and then calculate the current and voltage va...
What is the difference between lithium batteries and storage batteries? When searching for lithium batteries, many articles related to lithium batteries will appear. In these articles, storage batteri...
I received the 091 board from the group purchase, thank you for that. I won't post the pictures, they are all similar anyway. But the 091 has 32K memory, which is pretty good....
There are many different ways of human-computer interaction. The more common ones are listed below:
Mouse interaction: Using a mouse to operate a computer and interact was the most common human...[Details]

Bluetooth technology is a short-range wireless communication technology designed to replace wired cables. It is a wireless communication technology standard developed by the SIG, ...[Details]
ISP devices, such as field programmable devices (FPGAs and CPLDs), do not require a programmer. Using programming kits provided by the device manufacturer, they employ a top-down modular design app...[Details]
As the scale and business applications of national e-government networks continue to expand, the data and services transmitted over them are becoming increasingly sensitive and critical. To protect...[Details]
Normally, we determine our location and where we want to go by comparing our surroundings with observation and simple GPS tools. However, this kind of reasoning is very difficult for self-driving c...[Details]
Coal mines typically contain gas and coal dust. When gas and coal dust reach a certain concentration, they can cause explosions. Electrical equipment generates arcs during normal operation or durin...[Details]
Chinese characters are extensive and profound, and there are many different names for ESD tubes. How many of them do you know?
As far as I know, ESD diodes are currently known as ESD p...[Details]
Bosch has released a new SoC series to support L2+ advanced driver assistance functions. The chip integrates high resolution and long-range detection capabilities, and has built-in support for neur...[Details]
Over the past decade, the narrative surrounding fuel vehicles has been one of decline and replacement. Under the onslaught of new energy vehicles, traditional automakers have been forced to acceler...[Details]
Preface
Low-voltage motors are widely used in nonferrous metallurgical plants. Their abnormal operation not only impacts normal production but can also threaten human life. Therefore, providin...[Details]
Inverter power supplies on the market can generally be divided into two categories: sine wave inverters and square wave inverters. Some engineers also like to categorize pure sine wave inverters as...[Details]
MQTT Ethernet I/O modules primarily collect I/O port information and transmit data over the network. In addition to being a TCP server, Ethernet I/O modules can also function as TCP clients. Furthe...[Details]
The driving mode is not unfamiliar to vehicles. According to the driving mode of the vehicle, there are front-wheel drive, rear-wheel drive and even four-wheel drive. Four-wheel drive is a major se...[Details]
For self-driving cars, LiDAR is the sensory organ that allows them to "see the road." Simply put, its operating principle involves sending out a laser beam, receiving the echo, and ultimately gener...[Details]
