Looking for driver development experts to cooperate, mainly in Windows and embedded Linux. The main content is development guidance, consulting and training. Details will be given later. If you are in...
Hello everyone, thank you for reading this post! I am a fresh graduate from a local university, and my major is electronic information engineering. In late May 2006, I decided to go out to work sudden...
I only wrote a program to set the 11th pin of GPIOB, and did not touch other pins. The voltage is always 0. Why is that? The pin clock and other settings are all correct. It is set to output mode. I a...

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]
1 Introduction
The multifunctional monitor is a commonly used clinical medical device. It can display the patient's electrocardiogram (ECG), respiration (RESP), blood oxygen saturation (SP...[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]
Pulse oximeters, non-invasive instruments used to monitor a patient's blood oxygen saturation, are benefiting from moving away from expensive discrete component solutions toward more integrated design...[Details]
Introduction: Design of automated test systems
Challenges
To ensure the quality and reliability of products delivered to customers, test managers and engineers use automated test system...[Details]
In the development of high-stability lasers, real-time monitoring of the working state of the laser is an issue that needs to be focused on. This system realizes the high-stability laser temperatur...[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]
WiMax technology needs to demonstrate its advantages in specific application scenarios in order to gain market recognition, which requires application testing to measure system performance para...[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]
Adding "intelligence" to measurement systems is becoming more common as 8-bit microcontrollers are inexpensive, widely available, and can be programmed using today's common high-level languages, su...[Details]
As microcontrollers become less expensive and more powerful, electrical designers are finding it more cost-effective to use multiple small controllers in both single-board and multi-board systems. ...[Details]
This article first briefly introduces the working principles of current mode and voltage mode and their respective advantages and disadvantages; then discusses the ideal voltage mode using output c...[Details]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pres...[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]
