2、研（講師） ） 完成時間 2012 年 5 月 15 日 基于單片機的波形發(fā)生器的設計 IITHE DESIGN OF WAVEFORM GENERATOR BASED ON SINGLE-CHIP MICROCONTROLLER ABSTRACTThis article describes the the design of the waveform generator based on single-c

3、hip, the entire system through the microcontroller STC89C52 controls the DAC0832 that can finish convertting eight digital into the five waveform analog output of sine wave, square wave, triangle wave, saw tooth wave and

4、 pulse wave. The waveform generator consists of two parts: system hardware design and system software design, in the system hardware design, the microcontroller STC89C52 is the core of the design, through I/O interface d

5、esign to extend the DA converter module, waveform selector buttons, 74LS165 module the parallel input string line output and the LCD1602 module of frequency, magnitude of the display. And through the SCM simulation softw

6、are PROTEUS7.5 to design and produce of the printed circuit board (PCB) of the waveform generator. System software design is done with assembly language in the integrated development environment WAVE6000, including the m

7、ain Program, four waveform generator subroutine, key functions and display subroutines modules. This system can realize that frequency and amplitude of waveform is real-timeadjustable and flexible. The system development

8、 costs is in the hundred with a high accuracy, the error is small, low power consumption, faster data transfer speeds, high reliability, there is a certain development value. The tested frequency and amplitude of the sys
