A few days ago, I disassembled a hard disk. The motor inside is a four-wire one. I want to use this hard disk as a hard disk clock. The phase sequence of this brushless motor is like this. What kind o...
This is the design and implementation of an LCD controller based on FPGA. It is required to implement English characters and Chinese characters. The characters are no problem. Chinese characters are a...
I have read the source code of mbed these days, and the interface encapsulation for upper-level application calls is quite good. The code quality is relatively high, the comments are also very detai...[Details]
CMSIS Driver has similar API functions and similar calling methods. It is a further encapsulation based on the ST HAL library. It is much more convenient and simpler to use and configure than the ST ...[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]
Recently, the " ZTE
incident"
caused by the Sino-US trade war
has caused heated discussions in the electronics industry. It not only reflects that Chinese companies are lagging behind in the...[Details]
In Windows environment, the source code is encoded in UTF-8. If the source file created by STM32CubeMX contains Chinese comments, then using STM32CubeMX to regenerate the source code will cause the C...[Details]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
After studying the F4 FSMC method to drive the touch screen for a few days, I have gained some understanding, which are listed below. The unorganized record is only for my own reference in the future...[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]
Artificial intelligence
There is no inherent bias in AI. It does not "think" something is true or false for reasons that cannot be explained by logic. Unfortunately, human bias exists in mach...[Details]
From last year to now, competition in the photovoltaic inverter industry has become increasingly fierce. In addition to the introduction of new products, various marketing and promotion methods hav...[Details]
