The development board is ML507, the chip is Fx70t, and the Ethernet port of the board is directly connected to the Ethernet port of the desktop computer with an Ethernet cable. The connection indicato...
I plan to use nRF24LE1 to make a product. I need to improve the transmit power and receive sensitivity, so I need a wireless front-end chip. I have found a cc2591 from TI. Could you please recommend a...
I use an external crystal oscillator as the clock source. The program is as follows: RCC_DeInit(); RCC_HSEConfig(RCC_HSE_ON); if(RCC_WaitForHSEStartUp() == SUCCESS) { RCC_HCLKConfig(RCC_SYSCLK_Div1); ...
I have had some time recently and saw some interesting anecdotes. Let me first talk about the reverse recovery of diodes in power frequency rectifier and filter circuits. A group of nerds quoted from ...
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
Battery life is critical for portable applications. For applications such as smoke detectors, security devices, and thermostats, factory-installed batteries need to last for more than 10 years. The...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Vertical cavity surface emitting lasers (VCSELs) are gradually replacing traditional edge emitting lasers, especially in low bandwidth and short-distance communication systems where cost factors ar...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
Experimental tasks
A DS18B20 is used to form a temperature measurement system. The temperature measurement accuracy reaches 0.1 degrees. The temperature range is between -20 degrees and +50 de...[Details]
In 2012, more than half of the cars in the European, Japanese and American car markets will be equipped with color displays, navigation systems, satellite communications and other in-vehicle infota...[Details]
At present, the traffic congestion in cities is quite serious. According to relevant news reports: In China, the traffic congestion has expanded from megacities such as Beijing, Shanghai, and Guangzho...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
