LPC双核单片机，触摸液晶LCD的简单应用(LPC microcontroller, LCD touch LCD simple application)

说明：  根据stm32f103自带DA功能和DMA实现输出正弦波,可根据改变定时器周期改变正弦波频率。(According to the DA function and DMA of stm32f103, the output sinusoidal wave can be realized, and the frequency of sinusoidal wave can be changed according to the period of timer.)

说明：  由于超声波指向性强，能量消耗缓慢，在介质中传播的距离较远，因而超声波经常用于距离的测量，如测距仪和物位测量仪等都可以通过超声波来实现。利用超声波检测往往比较迅速、方便、计算简单、易于做到实时控制，并且在测量精度方面能达到工业实用的要求，因此在移动机器人研制上也得到了广泛的应用。(Because of its strong directivity, slow energy consumption and long propagation distance in the medium, ultrasound is often used for distance measurement, such as range finder and level gauge, which can be achieved by ultrasound. Ultrasound detection is often fast, convenient, simple in calculation, easy to achieve real-time control, and can meet the requirements of industrial application in measurement accuracy, so it has been widely used in the development of mobile robots.)

说明：  使用stm32f407zgt6的tim14定时器输出pwm波(Output PWM wave with tim14 timer of stm32f407zgt6)
