FALLING 下降沿触发 HIGH 高电平触发(该中断模式仅适用于Arduino due) 如果不需要使用外部中断了,可以用中断分离函数detachInterrupt(interrupt )来取消这一中断设置。 Example Code用外部中断实现LED的亮灭切换 1constbyteledPin =13;//LED的引脚2constbyteinterruptPin =
Arduino Due 是一块基于 Atmel SAM3X8E CPU的微控制器板.它是第一块基于 32位ARM核心的arduino. 它有54个数字IO口 (其中12个可用于PWM输出),12个模拟输入口,4路UART硬件串口, 84 MHz的时钟频率, 一个USB OTG接口, 两路DAC(模数转换),两路TWI,一个电源插座,一个SPI接口,一个JTAG接口,一个复位按键和一...

The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Metro Mini or a Trinket M0, but when size isn't as much of a concern, we reach for an Adafruit METRO. ...
实验:SPI通信 软件模拟SPI通信 实验:使用 74HC595 串口通信简介 arduino支持的串行通信有UART,I2C和SPI三种通信协议方式 根据串行数据的传输方向,我们可以将通信分为单工,半双工,双工 单工 是指数据传输仅能沿一个方向,不能实现反向传输 半双工 是指数据传输可以沿两个方向,但不能同时进行传输 ...
