Sorry, I just got started with LWIP. When I was doing TCP communication, I encountered a problem. The computer was the client and the target board was the server. The computer sent a TCP data packet, ...
I have complained before about the unstable AD results of LPC1343, and I also said that it may not be a problem with the chip, but it may be due to circuit factors.Looking at the new circuit of TinyM0...
As shown in the figure, NRF905 can be set to several specific frequencies in the 433MHZ band. I would like to know what the maximum frequency can be set to in the 433 band. Is it 1 for each byte, 433 ...
When I was doing my graduation project, I needed to use an SD card to expand the storage. So I wanted to know how to write the SD card driver in CE4.2. I also wanted to see the driver provided by the ...
[i=s] This post was last edited by Shiyu on 2015-1-23 16:31 [/i] Recently I want to work on uclinux, LWIP and other things, and I may use F4 chips in my work. I am looking to buy two STM32F429IDISCOVE...
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]
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]
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]
Preface
In recent years, many compact portable electronic products have been developed, such as mobile phones, digital cameras, MP3, MP4, PDA, GPS and DVD, etc. They are not only small in size...[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]
1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
1 Introduction
Intelligent software agents are software programs that can perform specific tasks for users, have a certain degree of intelligence, can autonomously perform some tasks, and ...[Details]
Abstract:
Under high dynamic conditions, combined with GEC's twelve-channel correlator GP2021, this paper discusses the structural design of GPS receivers and the key technologies inv...[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]
Portable products are generally powered by batteries. Due to cost and size considerations, there is a trend to reduce the number and size of batteries used in design. If the number of batteries is ...[Details]
Abstract: In many SCART applications, due to the complex signal switching requirements, dedicated ICs are usually used to implement SCART connections. This will bring cost pressure to single SCART ...[Details]
Mesh network architecture and advantages
The Internet is a flat network. The routers that make up the Internet are on the same plane. The mesh network formed by multiple paths between ...[Details]
1 Introduction
In many communication systems, the base station usually sends a training sequence for the terminal to synchronize with the system. The synchronization here includes time syn...[Details]
0 Introduction
Electric vehicles are high-tech products that integrate computer technology, communication technology, electronic technology, and new material technology. They have a complex ...[Details]
The growing global interest in green power has added new variables to the design of power supplies and power adapters. Designers must not only traditionally consider the design specifications requi...[Details]
