STM32产生频率可调正弦波锯齿波三角波LCD界面控制.docx

1、STM32产生频率可调正弦波锯齿波三角波LCD界面控制 STM32产生频率可调正弦波、锯齿波、三角波&LCD界面控制此程序能输出两路通道，三路波形，利用STM32的DAC，TIM，LCD，和DMA控制的发射出正弦波，锯齿波和三角波，每种波形频率可调，独立输出，独立显示频率，使能。最高频率达12.5KHz。三种波形都是有一个简易小UI界面，电阻式触摸屏，能够完全手动控制通道的选择，波形的选择频率的选择以及各种波形的使能。/*使用手册：0.初学即兴所敲，不喜勿喷。1.通道1和通道2只能分开输出。2.只有选中响应的波形选择框，才能设置频率或者使能。3.使能端只能在通道1或者通道2打开的情况下才能被使

2、按下操作有效。4.每次使能一个波形，其他波形使能将自动关闭。5.当通道1和通道2都关闭，使能将自动无效。6.通道1和通道2切换，必须重新使能。7.开发平台为STM32战舰版。 USER：Zhang Changhao*/#include led.h#include delay.h#include key.h#include sys.h#include lcd.h#include usart.h #include 24cxx.h#include flash.h#include touch.h #include STM32_WaveOutput.h u8 t,Mode1,Mode2,Mode1_Fl
