ReadASCIIString - 分析整数里一个用逗号分隔的字符串,来使一个LED灯褪色。 SerialCallResponse - 通过一个呼-应的方法(握手)来发送多个变数 SerialCallResponseASCII - 通过一个呼-应的方法(握手)来发送多个变数,并在发送前解码(ASCII)这些数值。 SerialEvent - 使用SerialEvent()函数 VirtualColorMixer - 从Ard...
This example shows how to enable callbacks to read streaming ASCII terminated data from an Arduino® Due using the serialport interface. Load Program on the Arduino Plug in an Arduino Due to your computer. Load the following program on the Arduino Due using the Arduino IDE. This program ...
int blue = Serial.parseInt(); 一旦你把数据读到你的变量,检查是否有新的字符需要继续读取: if (Serial.read() == '\n') { 用constrain(),你可以使这些值保持在PWM控制的范围内。用这种方式,如果这些值超过PWM的范围,它将会限制在一个可行的数值。从255里减去这个数值,你就可以得出用来控制LED灯的值。
