In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
This summary will introduce the transmitter characteristic test of TD terminal products - uplink power control. According to the 3GPP TS34.122 standard, UE uplink power control is divided into uplink ...[Details]
As the whole equipment is becoming increasingly miniaturized and power-saving, low-dropout linear regulators (LDOs) with low power consumption are becoming the mainstream in the market for linear regu...[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 pressur...[Details]
Abstract: Based on the research of the communication process between the reader and the RFID tag, combined with the EPC C1G2 protocol and ISO/IEC18000.6 protocol, a digital circuit of RFID tag appl...[Details]
Wireless personal area networks (or WPANs) are particularly useful for sensing, monitoring, and control applications. Cost-effective WPANs have the unique potential to implement wireless connectivi...[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]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
From the moment AVS video was born, scientists and engineers have been working tirelessly to reduce the size of audio and video bitstreams. Various advanced video compression algorithms have emerge...[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]
With the continuous emergence of new technologies and the increasing complexity of DSP real-time systems, there are more and more different types of external devices. Writing drivers for these exte...[Details]
With the rapid development of network technology and information communication, network economy and knowledge economy are no longer the exclusive domains of IT and other high-tech industries. The i...[Details]
Combined with Samsung's ARM9 series embedded processor S3C2410, this paper explains how to perform modular programming of LCD driver and how to statically load the driver into the system kernel.
