void setup() { // put your setup code here, to run once: } 说明:Arduino板起动,setup()函数被调用。初始化变量,引脚模式,使用某个库等。在Arduino板的上电和复位时只运行一次。 void loop() { // put your main code here, to run repeatedly: } 说明:用程序改变状态和响应事件,实时控制arduino板...

在loop()中没有使用delay()函数来做延时处理,因为与数码管类似,这种LED显示设备需要不断刷新,delay()函数使程序暂停等待延时会造成显示闪烁甚至熄灭的情况。使用for循环来控制显示的次数,进而控制显示时间来达到延时效果。
与ThreadHandler线程相比,loop函数的优先级为-128。 如何使用? 线程可以通过c++继承来创建 class MyThread : public Thread { public: MyThread() : Thread(priority, period, offset){} virtual ~MyThread(){} virtual void run() { //code to run ...

void loop() { displayTime(); // display the real-time clock data on the Serial Monitor, delay(1000); // every second } You have to change a few code setups before uploading the code to your Arduino. Open the code in your IDE Scroll down to the void setup menu, where you see a...
之前我们在一个for循环示例中使用了analogWrite()。现在我们编写代码在 Arduino 上实现这个例子。在Arduino IDE 中创建新的草图。 将草图另存为PWM_Example。 将代码更新为: int PWMPin = 11; void setup() { // put your setup code here, to run once: pinMode(PWMPin, OUTPUT); } void loop() { /...
