I am using the 2.6.29 kernel that comes with the mini2440 CD-ROM data from Friendly Arm. After I configure and compile the image myself, it always stays on the boot interface when I download it to the...
I like the blogger's articles very much, so I must read them whenever they come out. I think this article will at least prompt us to think about something, so I share it with you: [b][url=https://bbs....
There is a product that uses DW01 as battery protection, but when DW01 is powered off, there may be no voltage output, and C and GND need to be shorted, or a charger needs to be connected to activate,...
Everyone, please take a look at why this is happening. Sometimes it works, sometimes it doesn't. I'm looking for some advice from an expert. The answers to other people's posts before either don't mak...
Regarding the power supply problem of portable instruments: Sometimes software is required to turn the machine on and off, and the microcontroller and peripheral circuits each use a voltage regulator ...
When compiled with IRA:Fatal Error[Cp001]: Copy protection check, No valid license found for this product [24]What is the reason? Please help! I have been confused for a long time! I can't use it even...
The radio frequency identification (RFID) market is experiencing strong growth, with sales reaching $1.7 billion in 2004 and expected to reach $5.9 billion in 2008. This surge in demand is driven b...[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]
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]
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]
To help improve DC/DC conversion efficiency at lighter loads and higher frequencies, Schottky diodes can be integrated into MOSFET chips to form a single package to reduce power dissipation in the ...[Details]
introduction
Controller Area Network (CAN) is a bus standard proposed by Bosch of Germany to solve the information communication between automotive electronic control units. With its excel...[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]
Overview
In recent years, the vigorous development of integrated circuits has created a huge space for the research and application of digital circuits. FPGA has low power consumption, high re...[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]
Introduction
The MAX2116 P1db data is measured at specific combinations of RF and baseband gain over the adjustable range of these two gains. These data can be used to select gain control se...[Details]
Abstract This paper
introduces a wireless radio frequency transmission chip nRF9E5 based on 8051 core. The remote control system of flapping-wing micro-aircraft is made by using this chip. Th...[Details]
1 Introduction
The high temperature tester is mainly used for temperature tracking measurement and data acquisition during the heating process. By systematically analyzing the test data,...[Details]
With the rapid development of my country's power industry, the power system has higher requirements for the collection of power generation, transmission, distribution and consumption. As a prerequis...[Details]
Abstract: By controlling the supply voltage of the radio frequency (RF) power amplifier (PA) in a CDMA/WCDMA cellular phone, the PA efficiency can be improved, heat generation can be reduced, and t...[Details]
In the process of RF transceiver application, adjusting the processing gain (PG) of the direct sequence spread spectrum communication system (DSSS) can obtain excellent anti-noise performance, whic...[Details]
