I am reposting an engineer's article because I think it may be inspiring to many friends, so I am reposting it here: Microcontrollers are a very practical subject. Without practice, everything is just...
Recently, the servo drive keeps giving alarms. I hope you can give me some guidance. Thank you very much! I use a servo system of Delta ASDA-AB series 0.2KW. It keeps giving "ALE09" alarm. According t...
Usually, one power module can solve industrial problems, but in some super-large equipment load transmission, one power module may not meet the requirements, and multiple power modules need to be conn...
[i=s]This post was last edited by fan12398 on 2015-9-12 19:24[/i] Looking at the datasheet of AD7903, its common-mode input voltage is as shown in the figure below, 0.475*Vref ~ 0.525*Vref. If 2.5V Vr...
I'm learning about the M22 wireless module recently. I use it to send text messages. The commands are as follows: AT+CFUN=1 AT+CSCA="+8613800512500" AT+CMGF=1 AT+CMGS="+8613815269727" hello, but there...
The Sino-US trade war has already started. Trump's series of actions have had a negative impact on the global economy, such as increasing tariffs on Chinese companies and restricting domestic compa...[Details]
On April 24, Sungrow released its annual financial report. The report shows that in 2017, Sungrow's global shipments reached 16.5GW, of which domestic shipments reached 13.2GW, a year-on-year incre...[Details]
In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
In simple terms, high-end chips solve many complex problems, mid-range chips solve a single complex problem, and low-end chips solve a simple problem. Let's learn more about the relevant content wi...[Details]
LAN8720 test code arrangement 1. Modified based on two projects, namely "Experiment 55 Network Communication Experiment" of Zhengdian Atom ATK and "STSW-STM32070" routine of ST official The hardware ...[Details]
introduction In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[Details]
In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]
Recently, the "Smart Photovoltaic Industry Development Action Plan (2018-2020)" jointly issued by six departments has put this concept on the forefront. Photovoltaic smart solutions will become the ne...[Details]
Since China began to try to produce panels independently in 1998, in 2018, China's panel industry has gradually upgraded from a marginal industry to the largest production scale. Especially in the ...[Details]
The F1 racetrack is roaring with engines, and a fierce F1 race is about to begin. I am not a fan of racing cars, and I have nothing to do with this world, but
I spent a special day here

This program mainly uses the comparison output function of the timer to generate PWM waves to control the LED. The comparison output of timer A corresponds to P2.3 P2.4. Therefore, a matching working...[Details]
I rewrote the main part of this program. The program uses the watchdog as a normal timer and scans the digital tubes in the watchdog interrupt. In addition, I added a display buffer. If you want to d...[Details]
