I would like to ask an expert, can two chips with Bluetooth Smart single-mode function form a one-transmitter and one-receiver communication system?...
The chip I used to use was the Spartan-3AN series XC3S700AN, but now I have changed it to the Spartan6 series XC6SLX16. After the change, the program that used to run well on the XC3S700AN can no long...
[i=s]This post was last edited by paulhyde on 2014-9-15 03:21[/i] The frequency of AD9854 can reach 300M, but 9851 can only reach 180M. To output a 40M sine signal, both 9851 and 9854 need the help of...
When I used atmel9200 to initialize, I remember that the SDRAM initialization required waiting for a certain number of us, then precharging, then writing 8 refreshes, and finally writing the mode regi...
An alternative to lock-in amplifiers is to use a DC polarity reversal [1] on the current signal to remove noise. This is a well-established technique for removing offset [2] and low frequency noise [3...
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
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 order to highlight the concept of "energy saving and environmental protection" of intelligent buildings, solar street lights are designed for intelligent communities. The inclination and capacit...[Details]
As cellular phones become more advanced, the power consumption of the system during operation and the power consumption during standby are also increasing. Therefore, the power management design of...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
Power management solutions for today's portable application processors are becoming increasingly integrated. Total power consumption, standby and sleep current consumption affect battery size, bill...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[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]
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]
The automotive lighting and signal control system is responsible for controlling the vehicle's lighting, signal lights, electric horns, reversing and brake buzzers. Traditional automotive lighting...[Details]
