1.概述
Bluno M3是非常容易使用通用输入/输出数字IO口，GPIO端口是从数字0到38。
2.GPIO 模式
每个GPIO管脚都可以通过 pinMode()配置成数字输出或者输入等。
3.GPIO 参考函数
pinMode()
digitalRead()
digitaalWrite()
4.参考例程
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
