I have a question. I have written the driver for my serial port 1 under uclinux and transplanted it to 44b0. The serial port 0 has its own driver. Now the problem is, I can't figure out how to connect...
I'm decoding a set of data recently, and the data checksum is the last two bytes. Can you help me think about what calculation methods are generally used for two-byte checks? For example, there is a d...
The wireless voice communication system provides a voice dispatching function. On the basis of the existing fixed-line telephone terminals, wireless telephone terminals connected to the wireless netwo...

Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[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]

System Block Diagram
The system uses DSP56F826 chip as the core control module and CMOS digital image sensor chip. The image acquisition resolution can reach 640×480 pixels. When high-re...[Details]
Abstract: Based on FPGA hardware, the image scaling with fixed magnification is realized. The 2D convolution operation is decomposed into 2 1D convolution operations. The input original image pixel...[Details]
This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]
Conventional crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350-450μm, which are sawn from pulled or cast silicon ingots. Therefore, more silicon materi...[Details]

introduction
Since the 1990s, with the continuous reduction of the feature line width of integrated circuits and the corresponding increase in chip density and operating frequency, reducing po...[Details]
The Cirrus CS485xx DSP family provides high-performance post-processing and mixing of digital audio. Dual clock domains provided on the PCM input allow mixing of audio streams with different sampli...[Details]
PIC16F87X series microcontrollers are products launched by Microchip. They use RTSC structure, with data line and instruction line separated, i.e. Harvard structure. This allows instruction fetching a...[Details]
1 Introduction
In production, many machines require both forward and reverse rotation, and often require rapid starting and braking, that is, a reversible speed regulation system is needed. The...[Details]
