The GPRS module MC35I is connected to the COM1 of the PC. I use the HyperTerminal to input AT commands, but the HyperTerminal cannot input AT, that is, it does not receive input at all. It was working...
I just came into contact with this kind of board, SEED-DVS6467T. All the platforms are set up, but I am confused about how to use it for programming development. After compiling the DSP program in CCS...

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]
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[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 to achiev...[Details]
The U.S. Food and Drug Administration (FDA) points out that home health care is the fastest growing area in the medical device industry. Driven by the increase in average life expectancy, the increasi...[Details]
Ultrasound systems are among the most sophisticated and complex signal processing instruments in widespread use today. Like any complex instrument, there are many trade-offs to be made in implement...[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]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m~1kHz), audio (20Hz~20kHz), video (20kHz~10MHz), radio fre...[Details]
introduction
Mobile phones, MP3 players, hard disk players, digital cameras, PDAs and other devices are all controlled by navigation keys. Currently, the more popular navigation key contro...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
Electrocardiogram is an important means of diagnosing heart disease. However, due to various reasons, it is difficult to capture abnormal electrocardiograms with ordinary electrocardiographs. Although...[Details]

The full name of RFID is Radio Frequency Identification, which uses radio frequency to realize data transmission between programmable controller (PLC) or microcomputer (PC) and identification, ther...[Details]
For mobile phone products, using low-cost components in design is only the first step to make the price competitive. The cost of the production process, especially the cost incurred during the fina...[Details]
The teardown of the third-generation iPhone shows that the phone is more integrated and may cost less, in part because of the use of chips from Broadcom and Toshiba. One analyst joked that the "S" ...[Details]
The four-element infrared detector uses photosensitive elements, and the alarm is triggered only when each detector detects a signal. It has stronger anti-false alarm capability and better detectio...[Details]
