Today is the Coder's Day. Although most of the EE fans on 10.24 are hardware geeks, they are also half coders. I wish you all a happy holiday! [b][color=#5E7384]This content was originally created by ...
The power-on reset POR (Power OnReset) of the 80C51 microcontroller is essentially a power-on delay reset, that is, the microcontroller is locked in the reset state during the power-on delay period. W...
The GPIO in 2812 is divided into many groups: GPA, GPB, GPD, GPE, GPF, GPG.We abstract the groups.
Group abstraction: CGpio classUse namespace to wrapthe class namespace NF281x{class CGpio{CGpio( cons...
Yesterday we selected the host machine, so today we need to install TFTP and minicom. This way we can debug BeagleBone Blackle under the virtual machine. Let's install TFTP service first. With this, w...
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]
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer

1. Introduction
RFID (radio frequency identification) is a non-contact automatic identification technology that emerged in the 1990s. It uses the characteristics of radio frequency signal prop...[Details]
With the rapid development of science and technology, especially the widespread application of digital technology and various ultra-large-scale integrated circuits, electronic equipment, especially...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[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]
Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[Details]

Testing the temperature of steel billets before rolling is an important measure to ensure the quality of steel. Traditional manual testing is difficult to ensure product qu...[Details]
The concept of state machine
State machine is an important concept in software programming. More important than this concept is its flexible application. In a clear and efficient program, ther...[Details]
Among the many members of the single-chip microcomputer family, the MCS-51 series of single-chip microcomputers has occupied the main market of industrial measurement and control and automation eng...[Details]
From the previous section, we have learned that the timer/counter in the microcontroller can have multiple uses, so how can I make them work for the purpose I need? This requires setting the timer/...[Details]
introduction
MAX6636 is a multi-channel precision temperature monitor that can not only monitor local temperature, but also connect up to 6 diodes externally. Each channel has a programmable...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
