开发板的例子程序，在KEIL编译，下载到板，看结果和说明是不是相符，达到这样效果时，你心里肯定很秀激动，这时你真正学会了单片然后再学会看电路图，电路图其实很简单，就是一根线从一个地方连接到另一个地方，你写代码时，只记住单片机是哪一个管脚，然后对它写代码即可。-Examples of program development board, in KEIL compiler, download to board, look at the results and descr iption is not consistent, to achieve this effect, your heart must be very excited to show, then you really learn and then learn to see a monolithic circuit, schematic fact It is simply a line from one place to another place, you write code, just remember which one microcontroller pin, and then it writes code.
