In the article "TPS Creates a New Blue Ocean for IPTV", a new technical solution surfaced: TPS. The magic of this technical solution is that it can copy the Internet video service to the IPTV service ...
A while ago, a friend's company wanted to make a board with simple functions, but they didn't have hardware designers. They wanted to find a platform that could quickly evaluate the feasibility, cost ...
Dear experts, I downloaded the ucos porting program for stm32f10x from the micrium website. I found that in this program, if the priority of each interrupt is set to 0, the task scheduling is normal. ...
I read that PA.4 is the DAC output port. After writing the routine, I use a multimeter to connect one point to VREF- and one point to pin 29. If there is a sine wave output, the voltage value should c...
I am writing a virtual printer recently, and I don't know the difference between spl files and emf files. Is it as stated in http://www.cppblog.com/rawdata/archive/2009/02/23/74653.html that emf is a ...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();

I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[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]
Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
