Arduino技术及应用--第5章 Arduino的基本函数 Arduino技术及应用 第5章Arduino的基本函数 目录1 目录 5 目录9 5.1数字I/O 5.1.1pinMode(pin,mode)pinMode函数用于配置引脚为输入或输出模式，它是一个无返回值函数，一般放在setup里，先设置再使用。pinMode函数有两个参数——pin和mode。pin参数表示要配置的...
It will reconnect to the server if the connection is lost using a blocking reconnect function. See the 'mqtt_reconnect_nonblocking' example for how to achieve the same result without blocking the main loop. To install the ESP8266 board, (using Arduino 1.6.4+): ...
you can call this function to reset and generate a random seed・ You can use the random number as a random number seed, to ensure that the figures appear in a random way, usually use analog input as a random seed, which can produce environment related random number (e.g., radio, tel...
This is filled by a function that sets the slider value. We then define some audio parameters; then we move to the Setup. In Setup, we initialize the display. We then set the PDM object to have a callback function, which will be called every time that audio is received. After that,...
//for a one-microsecond delay, simply return. //the overhead of the function call yields a delay of //approximately 1 1/8 us. if (--us == 0) return; //the following loop takes a quarter of a microsecond (4 cycles) 5.4 时间函数 ...
