I installed DS 3.2 on WIN XP (SP3). I finally got SoftICE working. But when I set breakpoints for debugging, it often freezes and the keyboard and mouse don't work. I have to restart. I searched and f...
I am currently using Samsung 2450 chip. According to the datasheet, if you want to sleep, you only need to write a register PWRMODE = 2BED, and PWR_EN will automatically become low. But when I do this...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
Sensors have made inroads into automotive, medical, industrial and aerospace applications. But you may not see anything changing yet. Growing demands for safety, convenience, entertainment and efficie...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
Designers of handheld products such as cell phones, digital cameras, MP3 players and personal digital assistants (PDAs) are continually challenged to deliver more functionality in a smaller form...[Details]
1. Introduction
The intelligent detector discussed in this paper is an integrated semiconductor photodetector. Compared with traditional semiconductor photosensitive devices, its most ...[Details]
Some application designs have higher requirements on the speed at which the system's switching power supply can provide voltage output. Figure

Industrial control
often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]
Lifting wavelet transform not only has the advantages of traditional wavelet multi-resolution, but also simplifies the operation and is easy to implement in hardware. Therefore, it is widely used in d...[Details]
Murphy's Law tells us that "what can go wrong, will go wrong". In the testing or production process of video equipment, problems often occur when we least want them to happen and when it is leas...[Details]
Abstract This paper
introduces a wireless radio frequency transmission chip nRF9E5 based on 8051 core. The remote control system of flapping-wing micro-aircraft is made by using this chip. Th...[Details]
introduction
With the improvement of social automation, human-computer interaction capabilities urgently need a major change, and develop in a direction that is more convenient to use and more...[Details]
