Previously, some foreign technology media claimed that if Apple's iPhone did not support NFC , the day when NFC came to the fore might be delayed. This is indeed the case. The iPhone 4S launched by Ap...
I am here to ask for advice again... The function of the program is to first perform AD sampling on a signal, store the obtained data in an array variable, and then perform FFT transformation on the o...
[color=#503e2c][font=Oxygen, Arial,]I went to the park with my girlfriend. She said she wanted to play on the swing in front, so I went over to discuss with the kid who was playing there. I said, "Lit...
They are the same in circuit structure, both are diodes connected in series with a capacitor, the difference is that the rectifier uses a rectifier diode, and the envelope detector uses a high-frequen...
B-U585I-IOT02A comes with a VL53L5CX TOF ranging sensor. I am quite interested in this sensor, but unfortunately STM32Cube_FW_U5_V1.0.0 does not provide routines for this sensor (I found it by searchi...
The code is this... MemCopy was added, and release was also added at the beginning. I really don’t know where to change it... Please help me take a look......
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]

introduction
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]
Preface
Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[Details]
Controller Area Network (CAN) is a type of fieldbus. It is a serial communication network that effectively supports distributed control or real-time control and is recognized as one of the most pro...[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]
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]
In order to ensure the reliability of the driving assistance system and the basic functions of the car, and also to leave suitable connection interfaces for the car's future new entertainment and ...[Details]
Abstract:
QT1101 is a QTouch charge transfer (QT) device, a complete digital controller that can detect signals when approaching or touching up to 10 independent keys. It can be widely used i...[Details]
FSK (Frequeney-Shift Keying) uses carriers of different frequencies to transmit digital signals. FSK signals have the advantages of strong anti-interference ability and long transmission distance, and...[Details]
When it comes to ATX power supply, people will think of two "classic" ICs: pulse width modulation chip TL494 and voltage comparator LM339. The new dedicated control chip AT2005B has the functions ...[Details]
Focus shift problem
Visible light and infrared light have different wavelengths, so the imaging focus is not on the same plane, which results in a clear image under visible light condition...[Details]
With the development of LED technology, the application of LED has expanded from the traditional low-power portable product backlight to medium- and high-power indoor lighting, outdoor lighting, an...[Details]
With the development of the electronics and data industries and the promotion of distributed power supply systems in recent years, the application of DC-DC converters has become more and more wides...[Details]
As modern cities develop towards multi-functionality, urban layouts become increasingly complex, with hundreds, even thousands of ground monitoring points. To ensure that functional departments can...[Details]
