Some commonly used conversion tool functions in C language!
1. Convert string to hexadecimal
Code implementation:void StrToHex(char *pbDest, char *pbSrc, int nLen){char h1,h2;char s1,s2;int i;for (i=0...
I recently used a 5739 development board and tried a simple AD program. I did not set the clock and used an oscilloscope and the AD sampling period formula to deduce that the system clock was 1 MHz. I...
I am a hardware novice. I need to use an MCU and FLASH. The operating voltage of the MCU is 2.5V, ranging from 2.375 V to 2.625 V. The operating voltage of the FLASH is 2.7 V to 3.6 V. Do I have to us...
I'm using C++ in VS2005, and when I build a project in Smart Device (no matter which one), I can't jump to the wizard. It just pops up a dialog box with a fork, and there's no other prompt. It's stran...
As a wireless broadband metropolitan area network standard, WiMAX technology has greater advantages than previous 3.5GHz MMDS products in terms of non-line-of-sight transmission and spectrum utiliz...[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]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[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]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]

Improving the coordination of material handling and internal transportation between departments in modern factories is an important measure to achieve full automation of production. Traditional mat...[Details]
Abstract: Based on FPGA hardware, the image scaling with fixed magnification is realized. The 2D convolution operation is decomposed into 2 1D convolution operations. The input original image pixel...[Details]
0 Introduction
In microwave, radar, radio and television, and communication systems, the problem of coupling RF power is often encountered. A directional coupler is a directional power divide...[Details]
When programming in C and assembly, there are interface issues between variables and functions in C and assembly.
Variables defined in a C program are put into the .bss area after being compile...[Details]
1 Introduction
With the rapid development of the national economy, AC motors have played an extremely important role in industrial production. As the main traction motor in various industries,...[Details]
