The Arduino Due has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port, the fuse will automatic...

(以下实例基于Arduino Due) 1,接收函数Serial.read( ) int Serial.read(void) 如果串行数据缓冲区有数据,这个函数会读取串行数据缓冲区的第一个字节,数据读取位置移动到下一个数据缓冲区,也就是说如果继续读取的话会读取下一个数据缓冲区的第一个字节. 如果数据缓冲区没有数据,将返回-1. 2,发送函数Serial.prin...
Receives from serial port 1, sends to the main serial (Serial 0). This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc The circuit: * Any serial device attached to Serial port 1 * Serial monitor open on Serial port 0: created 30 Dec. 2008 m...
The Due has two usb connectors, the one with the micro-usb AB connector is the native one capable to act as an USB host, that means you can connect compatible external usb peripherals to the board, such as mouse, keyboards, smartphones. While the other USB port with the type B connecto...

Arduino Due拥有三个额外的 3.3V TTL 串行端口:Serial1位于 19 (RX) 和 18 (TX) 引脚;Serial2位于 17 (RX) 和 16 (TX) 引脚;Serial3位于 15 (RX) 和 14 (TX) 引脚。引脚 0 和 1 同样也被连接到了 ATmega16U2 USB-to-TTL 串口芯片的对应引脚,用于连接 USB 调试端口。此外,SAM3X 芯片还拥有一...
The Arduino Due has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, a USB-OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset...
确保你的Mega开发板通过USB连接到你的电脑,启动串口通讯。 voidsetup(){// initialize both serial ports:Serial.begin(9600);Serial1.begin(9600);}voidloop(){// read from port 1, send to port 0:if(Serial1.available()){intinByte=Serial1.read();Serial.write(inByte);}// read from port 0,...
