In my design, I first expanded a 6264 (the single-chip microcomputer uses P0 and P2 ports, uses a latch 74LS373, a decoder 74LS138, and the address lines are A13, A14, and A15). However, my design als...
Because I have just learned the analog-to-digital conversion of the 51 single-chip microcomputer, and have not yet learned CPLD and VHDL, I sometimes encounter some problems, so I want to make a frien...
My husband was born in the 1980s. He started out as a scholar, but he didn’t have the chance to receive free compulsory education or to be assigned to a higher education institution. He just happened ...

At the beginning of this century, Veit used Einthoven's galvanometer to record the electrical activity of the human pregnant uterus from the body surface for the first time. In 19...[Details]
Digital-to-analog converters (ADCs) provide the critical conversion of analog signals to digital signals in many systems. They perform amplitude quantization of an analog input signal to a binary fini...[Details]
Magnetic resonance imaging (MRI) systems for medical and scientific applications require a high-performance, high-power inductor capable of establishing a uniform, strong magnetic field. Transverse el...[Details]
Implantable Cardivoerter Defibrillators (ICDs) have been in common use for several years. ICDs apply a high voltage pulse between two electrodes connected to the heart, which detects cardiac fibrillat...[Details]
This article discusses how to use an ultra-low-power RF transceiver chip from Zarlink Semiconductor for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices t...[Details]
In some warehousing management, manufacturing, meteorological observation, scientific research and daily life, the requirements for temperature and humidity are common. For example, the "Interim Pr...[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]
JTAG Technology Introduction
One disadvantage of shrinking technology is that the complexity of testing small devices increases dramatically. When the board area is large, the board is tested...[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]
To ensure the success of China's TD-SCDMA network commercialization, operators and equipment suppliers need to conduct a large number of tests on networked equipment, among which RF testing is...[Details]
According to In-Stat/MDR, the number of mobile phones with Bluetooth capabilities will reach at least 300 million by 2005. One of the clear evidences of the increasing adoption of Bluetooth is that...[Details]
Combined with Samsung's ARM9 series embedded processor S3C2410, this paper explains how to perform modular programming of LCD driver and how to statically load the driver into the system kernel.
