println("Arduino for loop"); for (int i=0; i<7; i++) { Serial.print("i is : "); Serial.println(i); } } void loop(void) { } Notice how there are two statements - ending in semicolons and both are enclosed by curly braces. Compare this to the previous example that used ...
四个状态为“空闲”,“已按下”,“已释放”和“保持”。 boolean keyStateChanged() New in version 2.0: Let’s you know when the key has changed from one state to another. For example, instead of just testing for a valid key you can test for when a key was pressed. 2.0版的新功能:让...

Void Loop ( ) { } PURPOSE- 在创建了用于初始化并设置初始值的setup()函数后,loop()函数,正如它的名称所指,允许你的程序连续循环的更改和响应。可以使用它来主动控制Arduino板。 INPUT- - OUTPUT- - RETURN- - 3、Arduino数据类型 3.1 所有数据类型 ...
}voidloop() { lv_timer_handler();/*let the GUI do its work*/delay(5); } 烧录代码后的实验效果 2.跑lvgl库自身提供的示例代码 lvgl自身提供了很多的example,比arduino GFX库的LVGL的示例程序要丰富得多,所以我们需要把lvgl自身提供的示例程序跑起来,这样才更有利于学习lvgl。
在上述代码中,如果stopLoop变量为真,则使用return语句停止循环。 启动循环可以使用条件语句if来判断某个条件是否满足,如果满足则执行启动循环的代码。例如,可以使用一个布尔变量来表示是否启动循环,当该变量为真时启动循环。代码示例如下: 代码语言:txt 复制 bool startLoop = false; void setup() { // 初始化设置...
