C language uses awtk development interface to access http interface
AWTK, the full name of Toolkit AnyWhere, is a GUI framework based on C language developed by ZLG. It aims to provide users with a GUI engine that is powerful, efficient, reliable, easy to use, and can easily create cool effects. It also supports cross-platform synchronous development, programming once and using it for life. 1. […]

It turns out that PWM is so simple! The sawtooth wave is used as the carrier and the modulation wave is compared to generate the corresponding PWM output waveform
Table of Contents Fundamental How is PWM implemented? Classification program implementation Summarize Rationale The full name of PWM is Pulse-width modulation (Pulse-width modulation), which reduces the electrical A measure of the average power delivered by a signal; Therefore, according to the area equivalence law, the corresponding amplitude and frequency that need to be synthesized can […]
Waveform generator based on 51 microcontroller (PCF8591, sine wave, triangle wave, sawtooth wave, square wave)
Sine wave, triangle wave, sawtooth wave and square wave are the four most common waveforms in our daily life, so it is very important to learn how to use a single-chip microcomputer to generate these four waves. But after learning 51 single-chip microcomputer, you know that its IO pin can only output high level or […]
Swing implementation of AWT components
Swing provides corresponding implementations for all AWT components except Canvas, and Swing components are more powerful than AWT components. Components Compared to AWT components, Swing components have the following four additional functions: 1. You can set prompt information for Swing components. Use the setToolTipText() method to set helpful prompt information for the component. 2. Many […]
[Java AWT Graphical Interface Programming] Use the mouse wheel to zoom the background image drawn in the Canvas (drawing a large image + mouse drag + mouse wheel zoom + take the current mouse pointer position as the zoom center example)
Article directory 1. Set the zoom center point of the mouse wheel as the current mouse center point – key points analysis 1. Save the current mouse pointer pointing position 2. Recalculate the position of the picture according to the position and scale pointed by the mouse pointer 2. Draw a super large image + […]
