ADC，Analog-to-Digital Converter的缩写，指模/数转换器或者模数转换器 [1] 。是指将连续变化的模拟信号转换为离散的数字信号的器件。真实世界的模拟信号，例如温度、压力、声音或者图像等，需要转换成更容易储存、处理和发射的数字形式。模/数转换器可以实现这个功能，在各种不同的产品中都可以找到它的身影。(The abbreviation of ADC, Analog - to - Digital Converter, a/d Converter to or AD Converter [1]. Refers to the continuous changes of the analog signal is converted into a discrete digital signal)

基于STM32的12864LCD显示屏的驱动程序，通过8080时序并口通信，可以直接调用函数编写，使用起来很方便(Based on the STM32 12864LCD display driver, by 8080 the timing parallel communication, you can directly call functions written, easy to use)
