STM32产生频率可调正弦波、锯齿波、三角波&LCD界面控制.docx

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。
