[i=s]This post was last edited by smjusunn on 2016-7-7 17:35[/i] Hi everyone, today is my first time posting. As my technical level is relatively low, I am afraid that I can't explain it clearly, and ...
Now I have a newly soldered circuit board with 6 power supplies, including two 3.3V ones. Each one is not short-circuited to the ground, but the current is too large when it is powered on. What's goin...
Has anyone used FPGA to capture an image, store it in DDR, and then read it out continuously to display a still image on LCD? I have stored one now, but when I display it, the image always moves from ...

In the actual project development process, we often need to get the running time of a section of code. The usual method is to use an oscilloscope to measure it. This blog post will use SysTick to acc...[Details]
After searching a lot of information, I finally understood the time base timer. I did not use any library functions but operated the registers directly. The following introduces the systick in STM32...[Details]
1. The first project We are going to create the first project, which is mainly for project analysis, so that we can understand how CubeMX works and how to trace the code logic. Okay, no more nonsense...[Details]
Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows: Then, we need to use TIM1 to set PWM: Then,...[Details]
Timing and protocol are two key points in digital system debugging, and they are also where logic analyzers can play their most valuable role. How can we use a logic analyzer to quickly complete wiri...[Details]
When designing a product, if the application environment's requirements for power isolation are not considered, the product will be unstable due to improper design, and even high voltage may damage t...[Details]
The application of millimeter wave technology in mobile communications also involves a series of technical problems, including the large propagation loss of millimeter waves and the susceptibility ...[Details]
Superconductors have physical properties such as zero resistance effect, Meissner effect and Josephson effect, which make them have broad application prospects and unparalleled advantages in many b...[Details]
What is SYSTICK: This is a 24-bit system tick timer, SysTick, with automatic reload and overflow interrupt functions. All microcontrollers based on the Cortex_M3 processor can obtain a certain time ...[Details]
