在电子技术开发设计中，经常会使用到矩形波发生器，用于对一些功能的测试，

In the development and design of electronic technology, rectangular wave generators are often used to test some functions and verify the development and design schemes. Test the feasibility of the product through different frequencies. The basic principle of the traditional rectangular wave generator is the hardware chip design. The general rectangular wave generator normally has two terminals, one negative terminal and one positive terminal. <br>The STC89C52 single-chip microcomputer is selected as the main controller. The overall part is the design of the waveform generating circuit function, the design of the data display function, and the design of the button control function. The user can use the buttons to adjust the output signal generator style, and can output a rectangular wave, and display the frequency data of the rectangular wave through the LCD1602 module. The display scheme selects LCD1602 to display relevant information. Digital-to-analog conversion selects DAC0832. C language is used to realize the code design of the generator. The design includes the simulation analysis of the system, and through actual production and debugging, the product performance has been tested to meet the design requirements. The signal rectangular wave generator has practical application value in practical applications.

In electronic technology development design, rectangular wave generators are often used to test some functions and validate development designs.
