I posted a thread before asking for help with serial port printing. Because I have been using MDK+standard library, and recently I just learned the CUBE+HAL library, so I just took this board to pract...
[align=left]Before we officially start, let's take a look at the daily work of an FPGA engineer: Start designing code. Start writing the first always code. Found that a signal needs to be added, so wr...
Abstract: A fourth-order IIR digital filter is implemented using FPGA. Two second-order sections are cascaded to form a digital elliptic low-pass filter. The ripple in the passband is less than 0.1dB,...
Yesterday I went to attend the 2009 seminar of ST Company. I was unlucky and didn't win the prize. I couldn't resist the temptation of the three-in-one kit, so I took out a few pieces of silver and bo...
I would like to ask, for electronic products such as mobile phones, are the factory settings and the data we change later, such as phone numbers, stored in RAM or ROM? If it is RAM, why is it not lost...
Today's portable medical devices allow patients to diagnose and treat themselves, move around freely, and even use the devices when they are out and about. To achieve the "easy to carry" feature, po...[Details]
Magnetic resonance imaging (MRI) systems can take high-resolution cross-sectional perspective images of the human body, providing very useful information for medical diagnosis. The radio frequency pro...[Details]
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
Conventional ECG recorders are one of the main means for doctors to diagnose heart diseases, but they can only record short heartbeats. In many cases, it is difficult to record ECG changes during a...[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]
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]
Many MEMS devices, such as accelerometers and mechanical resonance devices, require a vacuum environment to realize their designed functions. However, verifying whether the package cavity has reach...[Details]
In the future, a complete automobile safety system must fully combine gyroscopes, accelerometers, steering wheel and brake pedal position detectors, and tire speed detection systems to accurately ...[Details]
Among the many candidate standards for China's mobile TV, the CMMB standard proposed by the Broadcasting Science Research Institute of the State Administration of Radio, Film and Television is aime...[Details]
Abstract:
This paper
introduces a data acquisition system based on USB and DSP, which takes advantage of the high-speed transmission characteristics of USB2.0. The overall structure of the ...[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]
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]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communication technology since the advent of digital communications. Many new wir...[Details]
A financial analyst pointed out that the signal reception problems of Apple's 3G iPhone may be caused by some defective chips.
