5、在行5中,通过函数 pinMode()将引脚led配置为输出模式; 6、在loop()中,行14 delay(100)表示延时100毫秒,digitalWrite(led, HIGH)表示把引脚25设置为高电平,从而点亮了灯;HIGH和LOW是用define定义的常量,LOW=0,HIGH=1。 可以看到,这个程序可读性很强,理解起来很容易,用户在使用Arduino pico的时候需要阅读的...

(2)程序设计程序设计的主要思路:Arduino Uno控制器通过DallasTemperature函数库实现单总线的启动、发送测量温度的请求、读取0号传感器温度,最后通过串口发送出去。 #include #include #define ONE_WIRE_BUS 2 //定义单总线连接的端口OneWire oneWire(ONE_WIRE_BUS);DallasTemperature sensors(&oneWire);void setup(void)...

Calling this function will reset all completed tests (passed, failed or skipped) back to their initial state. For tests that define asetupmethod, this will be run again on the nextTest::run(). If any tests were not completed yet, these are unaffected. The statistics (number of passed, fa...

It would be possible to work with the pin codes in this way, but the C language offers some tools to make the use more comfortable and safe. First, we will not define the pin code as a simple integer, but will create a new data type for it. This type is calledGP...
