Let's talk about the psychological preparation before maintenance. Although it is empty talk, it is necessary. I think in order to do a good job in maintenance, in addition to the corresponding knowle...
I am using W78LE516 to do a case recently, and I would like to ask you how to use the ISP function of W78E516. I only know that I need to write an ISP control program into the 4K LDROM of W78E516 thro...
I only learned simple knowledge of 51 single-chip microcomputers in class before. The specific operation was just to use Keil to write simple programs and use Keil's debugging simulation to see the re...
I've been working on the mixer in AUDIO recently. My audio driver model is wavedev2. But I put mixerdrv into it and nothing happened. The 8K sampled file was not converted to 44.1K when it was passed ...
Recently, I found that a large number of netizens support the development of "Smart Home System". In order to ensure that this project can be completed and not aborted halfway, the following game rule...

In the single-chip microcomputer system, in addition to display devices, sound devices are often used, and the most common sound device is the buzzer. Buzzers are generally used for some low-demand...[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]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[Details]
