[b] Electromagnetic interference (EMI) is a part of our lives. Over time, intentional and unintentional EMI radiators can wreak havoc on circuits. The signals from these radiators do not necessarily p...
No bargaining, dear 1. MSP430 development board. Single board with chip is 10 yuan. Brand new with packaging is 15 yuan. [img]https://img.alicdn.com/imgextra/i3/3030951366/TB2eAiOhY8kpuFjy0FcXXaUhpXa_...
I saw that the lighting lamp made by netizen devin9588 is very practical, so I shared it with you. First of all, there is nothing new about what I made. I just thought it was useful at the moment, and...
When I was playing with TFT screen before, the font library used 16*16 GB2312, and the file system used znFAT32. By default, znFAT32 provides short file names. After opening long files, it converts GB...
[size=5] Time flies so fast. One week has passed in the blink of an eye. In this post, I have roughly organized the idea of the health bracelet. This week, I mainly spent my spare time drawing the sch...
Usually the common mode inductor in a switching power supply is located at the position shown in the figure below.
Now we take power from an independent winding of a transformer, and perform DCDC step...
This article discusses how to wake up a touch-sensitive device such as a tablet without touching the device, using basic gesture recognition and novel proximity sensors. The article discusses the p...[Details]

summary
This article will briefly analyze the success and shortcomings of high-frequency DC-DC switching power supplies in the process of miniaturization (the second basic goal), and propose m...[Details]
The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]
Direct digital frequency synthesis (DDS) has fast frequency switching and modulation capabilities and is widely used. However, when low power consumption and low cost are the main considerations, D...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
