This is a switching power supply used to test resistance on our loop resistance tester. It has a 220V input and a 200A/10V output. There is also a 500A one, but I don’t have it on hand at the moment, ...
Anyone who has heard of HTML5 knows how powerful it is, such as more descriptive tags, multimedia support that is less dependent on plug-ins, cross-document messaging, Web Sockets, client-side storage...
I have made a light source. If I have any questions, please feel free to give me some advice. This light source uses PWM dimming and adopts STC12CLE5A48S2 single-chip microcomputer. LCD displays the b...
I would like to ask, is the waveform shown in the attached figure directly generated by software simulation, or is it a signal captured by an oscilloscope during hardware testing? Also, what software ...
Designing for automotive LCD displays larger than 5" can be complex. The display source driver requires a supply rail called analog voltage device drain (AVDD) in the 10V to 15V range and two supply ...[Details]
In order to strengthen the management of new energy vehicle charging facilities in our city, prevent and reduce accidents, protect the lives and property of the people, and improve the public safet...[Details]
1. Principle 1. Infrared emission protocol The infrared transmission protocol has been written in the previous article , so I will not repeat it here. 2. Timer counting and input capture A timer...[Details]
In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[Details]
1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]
Unlike three years ago, today's
artificial intelligence
is no longer just a floating concept, and the venture capital circle has begun to explore the various possibilities of this technolog...[Details]
In the project, CPLD is needed to complete part of the algorithm design. The parameters are given by AVR, so the communication between AVR and CPLD needs to be completed. Therefore, a test program is...[Details]
This paper combines embedded control technology with network control technology to realize the design of temperature control system based on single chip microcomputer through Internet control. Th...[Details]
On Sunday, the South Australian government unveiled plans to build the world's largest virtual power plant, which will connect at least 50,000 homes over four years and have a capacity ...[Details]
STM32 has two watchdogs: independent watchdog and window watchdog. This article mainly introduces the use of independent watchdog. Independent watchdog (IDWG): driven by an independent 40KHZ low-sp...[Details]
Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]
This program sets the LED running light and the 0-16 numbers of the 0th position of the digital tube to light up in a cycle. The digital tube program cannot be put into the main function, because the...[Details]
Timer Interrupt The timer function of STM32 is very powerful. There are advanced timers such as TIME1 and TIME8, general timers such as TIME2~TIME5, and basic timers such as TIME6 and TIME7. In th...[Details]
T1 or T2 are two timers/counters of MCS-51 microcontroller. The first method can use two timers/counters to generate rectangular waves. In order to save interface resources, the second method is used...[Details]
Design a program for the 51 single-chip microcomputer. It is known that the crystal oscillator frequency of the 89C51 single-chip microcomputer is 12MHz, and it is required to use T1 timing to output...[Details]
