Title: Drive the digital tube to display dynamically, and move from right to left on 8 digital tubes and display the number "2019" cyclically. Use the toggle switch or key as the external interrupt re...
First of all, I felt novel when I saw this level test, and then I thought of the kids of engineers in our forum... Then I thought of the ESP32 development environment that was complained by engineers,...
I suddenly had the urge to do a series of topics on sound visualization. This topic is a bit difficult and covers a wide range of areas. The related FFT and FHT algorithms are also quite complicated, ...

1 Introduction
Since the late 1980s, when variable frequency speed regulation technology entered the historical stage of industrial transmission, it has become the most influential industr...[Details]
Under normal conditions, the forward and reverse resistances between AK and AG of a unidirectional thyristor are relatively large (in the hundreds of kilo-ohms); the forward and reverse resistances b...[Details]
This is the interrupt timer principle of 51 MCU that I summarized, and I will attach the attachment later. This is my first post, so please forgive me for any shortcomings! The text I summarized is ...[Details]
Baud rate configuration can set the baud rate for UART operation through the configuration registers UART_IBRD and UART_FBRD. The baud rate calculation formula is: current baud rate = UART reference ...[Details]
