[i=s]This post was last edited by oxygen_sh on 2022-3-17 19:54[/i]I am going to use the National Technology M4 development board to make a three-phase motor control application. I searched the box and...
When applying AR1021X modular integration, some applications need to use modules as soft AP, which involves the hostapd configuration problem. If the configuration is not good, there will be no SSID h...
Problem description:For most chips, there is usually a soft start pin in the chip's function pins. Its function is to slowly increase the output voltage to the set value and reduce the inrush at the s...
1. I recently encountered this problem when adjusting the board: the board functions normally when the emulator is plugged in and running online, but some functions of the board are abnormal when it i...
We often come into contact with crystal triodes and are familiar with their use. Relatively speaking, we are a little unfamiliar with crystal field effect tubes. However, due to the unique advantages ...
Engine idle-stop technology, also known as start-stop technology, is popular in the European market with high oil prices, strict emission regulations and mandatory driving cycle standards to improv...[Details]
Recently, I helped a customer debug an STM8 program and used OptionByte configuration. When I searched online, I found almost all the information about how to implement it through functions. Then I c...[Details]
Huawei's Hongmeng OS 3.0 system will be released next month. The first batch of compatible models have been basically confirmed, namely Mate Xs 2, Mate X2, the entire Mate 40 series, and the entire P...[Details]
To achieve the highest performance and parallelism, the AVR uses the Harvard architecture with separate data and program buses. Instructions in the program memory are run through a one-stage pipelin...[Details]
A previous blog summarized the hybrid device driver model (http://www.cnblogs.com/ape-ming/p/5101322.html). Now let's write a button device driver based on the template listed in that blog.

The technology circle is always changing at an astonishing speed, but in this era when even MP3s are rare and streaming media is popular, the vitality of various music carriers is still quite t...[Details]
According to the detection principle, it can be divided into two categories:
1. One type uses the principle of electromagnetic induction to detect metal pipelines, electric/optical cables, and so...[Details]
There are at most 3 ADC modules in STM32, and the channels corresponding to each module do not completely overlap.
The figure below is the lower left corner of the general block diagram in the STM3...[Details]
Liquid crystal (LCD) TVs have become popular in the home appliance consumer market, because LCD displays require backlights, and traditional CCFL backlights have been gradually replaced by LED backlig...[Details]
