The first discussion post is shown in Figure 1. A PMOS tube-involved overvoltage protection circuit uses a voltage regulator tube VT1 to stabilize the voltage at 5.1V. This way, the overvoltage protec...
Slow power-on can easily cause a freeze, so consider using bor undervoltage protection. There is a line in the manual that says bor can be configured by software, but it does not specify the specifica...
I am planning to develop a bridge anti-collision system, powered by solar energy. I am planning to use infrared sensors to cut off the warning that the ship is too high and issue a voice alarm. The pr...
The application ClearCommError function prompts a CE_OVERRUN error. If (IntSubPndVal & (pHWHead->bErrINT)) in the driver's SL_GetInterruptType function is true, indicating that an error has occurred. ...
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]
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
No matter which processor you are learning, the first thing you need to understand is the registers and working mode of the processor.
ARM has 37 registers, including 31 general registers and ...[Details]
System design is a complex process. It is not enough to just use ICs. There are many details to consider. This article uses a high-fidelity music playback system as an example to introduce how to s...[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[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]
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]
In the "digital pressure measurement" experimental device of applied physics, the subject technical knowledge of analog circuits, digital circuits, sensors and single-chip microcomputers is used. In o...[Details]
People who often surf the Internet until late at night, their families always complain that turning on the big lights in the living room affects their rest, but some people don't have keyboard ligh...[Details]
The production process of lithium batteries does not mention the previous processes such as material preparation, winding, liquid injection, and packaging, but only talks about the final formation ...[Details]
Features
POE technology can ensure the safety of existing structured cabling while ensuring the normal operation of the existing network and minimizing costs. The IEEE 802.3af standard is ...[Details]
1 Introduction
CAN (Controller Area Network) bus is a kind of field bus. It is used in many industrial sectors due to its outstanding advantages such as high performance, high reliability, high...[Details]
1. Brief Introduction
