Arduino 硬件编程语言基础学习入门 voidsetup(){voidloop setup()函数中的代码只会被运行一次,通常用来做一些初始化工作;loop()中的代码会被无限次地重复运行,此函数为程序的主体部分。 2、程序中的值 2.1 变量和常量 常量是一个字面量,只可以表示一个特定的量。 2.2 变量类型 2.3 变量的作用域和修饰符 2.3....

return 关键字可以很方便的测试一段代码,而无需“comment out(注释掉)”大段的可能 存在bug的代码。 voidloop(){ //写入漂亮的代码来测试这里。 return; //剩下的功能异常的程序 //return 后的代码永远不会被执行 } 2.10goto 程序将会从程序中已有的标记点开始运行 语法 label: gotolabel; //从 label 处...
