Hey everyone in the forum, I have a question for you!
I have just started embedded development and I don’t know a lot of things. For embedded ARM development based on LINUX, I really don’t know where ...
This article discusses four commonly used FPGA/CPLD design ideas and techniques: ping-pong operation, serial-to-parallel conversion, pipeline operation, and data interface synchronization. They are al...
The ADC chip is AD7656. The waveform is normal when the frequency is 5khz. Now when the frequency rises to 10khz, the waveform intermittently appears as shown in the figure. Please give me some advice...
Should stepper motors be considered DC motors? Can I use only one 298 as the driver? I checked online and many people said it is possible, but why does the teacher say it is wrong?...
This paper establishes a fuel cell engine test platform based on the NI integrated hardware and software environment. This platform can realize the test and control of fuel cell engines and their a...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[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]

Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
When designing a PLC system, the control scheme should be determined first, and the next step is to select the PLC engineering design. The characteristics of the process and the application require...[Details]
Improving the coordination of material handling and internal transportation between departments in modern factories is an important measure to achieve full automation of production. Traditional mat...[Details]
1 Introduction
The early stage control system used relay control. Due to the large number of stage equipment, the number of control elements is huge and the wiring is complicated. Therefore, th...[Details]
At present, products in the field of monitoring generally focus on the field level, that is, the client/server (C/S) model is adopted, the purpose of which is to ensure the stability and reliability o...[Details]
