I designed a 4-key keypad using C51 programming. I want the program to determine whether the key is double-clicked or long-pressed. In the double-click recognition part, I want to set the interval bet...
This part is quite boring and requires patience. If you make a mistake in entering a command, the result may be incorrect. Then follow the above article [Altera SoC Experience Tour] + Lark ARM develop...
Recently, I was debugging a circuit that uses a transistor (NPN) to achieve high and low level reversal. As shown in the figure, I found a strange failure problem: after a short period of operation, w...
The circuit diagram is shown in Figure 1, and Figure 2 is the waveform on the sampling resistor R detected by a differential probe. The problem is as follows:
1. Which of the following methods is used...
I was debugging a program recently and wanted to see the waveforms of some variables. Since I don't have an oscilloscope, I could only use the Cube Suite+ simulator function to simulate the operation ...

With the increasing complexity of smart vehicle electrical and electronic architectures, the full lifecycle management of vehicle electronic control components faces multiple challe...[Details]
EtherCAT (Ethernet for Control Automation Technology) is a real-time industrial fieldbus communication protocol based on an Ethernet-based development framework. EtherCAT is one of the fastest indu...[Details]
Some time ago, I attended the 4th Energy Chemistry Forum of the Chinese Chemical Society and learned about high-energy-density and high-safety batteries. I would like to summarize and share this wi...[Details]
When discussing autonomous driving technology, there are often two extremes: on the one hand, there's the vision of "fully autonomous driving," while on the other, there's concern about potential s...[Details]
With the increasing number of new energy vehicles on the road, the deployment of supporting facilities for these vehicles has accelerated, and new energy vehicles have gradually entered the vision ...[Details]
Compared to cloud databases, minicomputers are purpose-built for decentralized, rugged computing at the edge of the network. By moving applications, analytics, and processing services closer to the...[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]
"We have successfully launched the first version of our dedicated chip for EMB brake-by-wire. Second-generation samples have also been successfully completed, and we are actively planning a third-g...[Details]
The MCX E series is the most reliability- and safety-focused series in NXP's extensive MCX product portfolio.
With the launch of this series, NXP has further enriched its 5V-compatible MCU pr...[Details]
In the period after the switching power supply achieved the "20 kHz" revolution in the 1970s, although improvements and enhancements were made in circuit technology, the development level of the se...[Details]
Plug-in hybrid vehicles (PHEVs) utilize two powertrains. Their pure electric range is typically inferior to that of pure electric vehicles, often reaching less than half that. Currently, mainstream...[Details]
For new energy vehicles, the importance of batteries is unquestionable. Not only does it determine the performance of the vehicle, but the battery density also has a great relationship with the veh...[Details]
As a pioneer in the new smart home concept, robot vacuums have captured a significant market share. Robot vacuums, also known as automatic sweepers, smart vacuums, or robot vacuums, are smart home ...[Details]
