I just came to the "Home of Electronic Engineers" and I don't know what to bring as a gift, so I will introduce to you several newly released embedded development boards this year that I know of.1. KI...
Phenomenon: Small data volume is normal, large data volume (thousands of registers to be read and written) is very slow.Solution: Change the communication baud rate with the touch screen to the maximu...
Recently, I have a simple image recognition case, CCD camera PAL output, TMS320VC5509a as processor, TVP5151 + FIFO structure. I finally finished the schematic diagram after piecing together. I am a n...
Dear heroes:I used sysgen to program a simple IIR module, which includes 2 additions, 3 multiplications, delay, etc.There is no problem with the simulation. When clicking on generation, it stays on th...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
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]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
With the development and widespread application of computer technology, especially in the field of industrial control, computer communication is particularly important. Although serial communication g...[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]
With the advocacy and implementation of the government's Safe City Plan, the security market has increasingly higher requirements for the clarity of surveillance images. Imagine that after a case o...[Details]
Experimental tasks
A DS18B20 is used to form a temperature measurement system. The temperature measurement accuracy reaches 0.1 degrees. The temperature range is between -20 degrees and +50 de...[Details]
Among the many members of the single-chip microcomputer family, the MCS-51 series of single-chip microcomputers has occupied the main market of industrial measurement and control and automation eng...[Details]
From the previous section, we have learned that the timer/counter in the microcontroller can have multiple uses, so how can I make them work for the purpose I need? This requires setting the timer/...[Details]
