I have never studied USB before, but now I need to build a USB system. It is roughly like this: we used Lingyang's SPCE061A development board to make a simple item manager. Now we want to add a USB in...
1 System Overview
As shown in the figure, this is the principle block diagram of the entire video acquisition system. At the beginning of power-on, the FPGA needs to initialize the register configurat...
Does anyone know how to sense a circuit 10 meters or more away? (That is, how to sense the voltage returned by the object or person in front of it) Can anyone tell me? I hope we can communicate with e...
I'm learning CC2530F256 recently. Now I'm debugging RF communication (simple RF communication, no protocol stack). Considering that there will be data collision during multi-point communication, how t...
Now there is a sinusoidal voltage with a peak-to-peak value of 1 to 1.5V. Can the peak value be detected using the following diagram? If not, is there any better method? Thank you very much! ! ! In ad...
I recently found a clever part when I was looking at the code. When you usually use 12864 or 1602 to display numbers, I believe everyone will first split it up, convert it into the corresponding ASCII...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer

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]
In this article, the high-performance DSP developed by TI can be used as an effective confidentiality method if it is applied to PC encryption cards.
As an effective network security solution,...[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]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
Contact resistance
is the resistance to current flow through a closed pair of contacts. This type of measurement is performed on devices such as connectors,
relays
, and switches. The...[Details]
I. Introduction
Since RS232 has a short communication distance (only 15 meters according to EAT/TAI-232 standard), and can only perform point-to-point communication, it cannot directly f...[Details]
1 Introduction to HART Protocol
HART (Highway Addressable Remote Transducer), an open communication protocol for addressable remote sensor high-speed channels, was launched by Rosemen in the U...[Details]
Digital array radar (DAR) uses digital beam forming (DBF) in both receiving and transmitting modes to achieve flexible distribution and reception of RF signal power in the airspace, obtain excellent t...[Details]
In recent years, with the rapid development of the information industry, dot matrix LED display screens have been widely used in various advertising and information display systems such as the fina...[Details]
TC9012F is a universal CMOS large-scale integrated circuit for infrared remote control signal transmission, suitable for remote control of TV, VTR, laser player and other equipment. In the market, ...[Details]
Today, the value of electronic components in cars accounts for 15-20% of the total vehicle. In the future, this proportion may be as high as 30-40% as more safety electronics, fuel consumption and ...[Details]
