I recently made two high-power charging devices (86V100A), using STM32f103RB as the human-machine interface, which can select voltage, current, time, etc.Considering that I am not familiar with this c...
Complete project files, including PCB diagram, schematic diagram, gerber diagram, and versions from different periods. It took me half a year to make it. It was made in 2006, when housing prices were ...
Hello everyone! I updated the software of Altium Designer 16 and found a problem, as shown in the picture, how can two components be stacked together? The current software will push two components whe...
I have an Easy2812 development board, but the emulator is XDS100-V2, which only supports CCSV4. After installing CCSV4, I imported the routine "CpuTimer2.pjt" that came with the development board CD t...
Recently, my boss asked me to develop a program using ce6.0 to turn off the alarm by shaking the phone. I used to develop games, so I really have no idea how to do this. I thought of a design pattern ...
Actually, the function I want to achieve is very simple, that is, I want to output a square wave on P1. But it is always incorrect. I will post the code to show you what is wrong. The board is 5438.#i...
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]

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[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]
In this article, the high-performance DSP developed by TI can be used as an effective confidentiality method if it is applied to PC encryption cards.
As an effective network security solution,...[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. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
Contact resistance
is the resistance to current flow through a closed pair of contacts. This type of measurement is performed on devices such as connectors,
relays
, and switches. The...[Details]

and become
superconductors
. Two parameters that are often measured are the transition ...[Details]
Today, the value of electronic components in cars accounts for 15-20% of the total vehicle. In the future, this proportion may be as high as 30-40% as more safety electronics, fuel consumption and ...[Details]
Abstract: With the development and construction of BeiDou II system, China will shift from the situation dominated by GPS to the situation dominated by BeiDou II global navigation system independen...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
At present, a large number of cooling tower fans, speed fans and special fans are in use in petroleum, chemical, pharmaceutical, metallurgical and other enterprises. Some fans have no monitoring in...[Details]
