ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor extensions: • The standard System Control coprocessor (coprocessor 15), which is used to control memory system components such as caches, write buffers, Memory Management Units, and Protection Units. • The Vector Floating-point (VFP) architecture, which uses coprocessors 10 and 11 to supply a high-performance floating-point instruction set. • The debug architecture interface (coprocessor 14), formally added to the architecture in ARM v6 to provide software access to debug features in ARM cores, (for example, breakpoint and watchpoint control).-ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor

应用背景本代码可以用于嵌入式图形界面设计、工业控制等。用户可以将其修改或者自行设计将其投入到自己的应用中。（压缩包中附带硬件资料，用户可以参考）关键技术本测试代码采用了正点原子的4.3寸电容屏，本人将其原先的查询方式获取电容屏的改为中断方式获取用户输入，查询的效率不仅低，而且占用CPU的资源，所以本人通过查询数据手册，将其修改为中断方式获取屏幕坐标。并在此基础上移植了STemwin嵌入式GUI，用户可以将其修改或者自行设计将其投入到自己的应用中。（压缩包中附带硬件资料，用户可以参考）

程序使用了STM32F103RBT6的AD和DMA，利用DMA使得AD传输的数据更快，节约了单片机的资源，能使ARM做更多相关的任务。
