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参数表示要配置的引脚，以ArduinoUno为例，它的范围是数字引脚0～13，也可以把模拟...
One potential way to improve upon this is to add a variable to the Encoder library, tracking themicros()timestamp of the most recent position update. I can then query that timestamp from my code later, instead of callingmicros()myself which pads an unknown delay. I found the encoder libr...

函数无返回值,原型如下:void delay(unsigned long ms){ uint16_t start = (uint16_t)micros( ); while (ms 0) { if (((uint16_t)micros( ) - start) = 1000) { ms--; 5.4 时间函数 start += 1000; } }} 可以在开发环境的下列实例程序中找到delay函数的应用:ADXL3xx.pde、AnalogInput.pde、...
