then in reverse.The circuit:* LEDs from pins 2 through 7 to groundcreated 2006by David A. Mellismodified 30 Aug 2011by Tom IgoeThis example code is in the public domain.http://www.arduino.cc/en/Tutorial/ForLoop*
bool stopLoop = false; void setup() { // 初始化设置 } void loop() { // 循环执行的代码 if (stopLoop) { return; // 停止循环 } // 继续执行循环的代码 } 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...
}voidloop () {for(inti =0; i <10; ++i )//initialize elements of array n to 0 {Serial.print (i) ; Serial.print (‘\r’) ; }for(intj =0; j <10; ++j )//output each array element's value {Serial.print (n[j]) ; Serial.print (‘\r’) ; } }...
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...

voidloop() { for(inta=0; a<256; a++)//这个循环的意思是让a这个变量+1一直加到到256,每次循环都进行下面的活动 { digitalWrite(latchPin,LOW);//将ST_CP口上面加低电平让芯片准备好接收数据 shiftOut(dataPin,clockPin,MSBFIRST,a); //这个就是用MSBFIRST参数让0-7个针脚以高电平输出(LSBFIRST 低...
}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。
