The ones I found online seem to be based on 2.0, and the 3.0 version seems to have only a systick_config function.I used the examples on the Internet to compile, and many functions were told to be und...
The data loss is even more severe when I change to a 1G card. The data loss for a 2G card is about one hour without loss, but starts after a long time. There is basically no loss of data when storing ...
MOS tubes, commonly used semiconductor devices, are widely used in analog circuit design. Here we summarize some common knowledge about discrete MOS tubes. (1) Pin definition For 3-pin packages, the p...
I would like to ask if there is a suitable chip that can achieve controllable adjustment of output frequency, specifically: the input is a 0-15V square wave with a duty cycle of 50%. Assuming the inpu...
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[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]
With the rapid development of computer technology, embedded image systems are widely used in office equipment, manufacturing and process design, medical, monitoring, sanitary equipment, transportat...[Details]
Over the past 15 to 20 years, automotive power MOSFETs have evolved from an initial technical topic to a thriving commercial sector. Power MOSFETs were chosen because they can withstand transient ...[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]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[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]
At present, the IEEE802.11 wireless LAN standard is widely used in voice communication, wireless office and other fields, but it is still mainly limited to wireless communication on general platfor...[Details]
introduction
Like other
portable
electronic products,
blood flow parameter detectors
need to be small, thin, durable, reliable, and have a long standby time. Therefore, system desi...[Details]
Preface
In the analog era, due to the unchanged specifications and relatively simple device connections, as well as users' low requirements for image quality, the relatively simple environment...[Details]
introduction
In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]
1. Introduction
The intelligent detector discussed in this paper is an integrated semiconductor photodetector. Compared with traditional semiconductor photosensitive devices, its most ...[Details]
Preface
For a long time, SD cards with Flash Memory as storage have been widely used in consumer electronic products due to their small size, low power consumption, erasable and non-volati...[Details]
Fetal monitoring is an important means to ensure the safety of perinatal mothers and fetuses and achieve eugenics. Intelligent fetal monitoring is a monitoring method that analyzes the health stat...[Details]
