Arduino Mega 2560 产品说明书 ARDUINO MEGA 2560 REV3 Code: A000067 The MEGA 2560 is designed for more complex projects. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects.This gives your projects...
External Interrupts 6个外部中断引脚 Six pins are used for creating external interrupts i.e interrupt 0(0), interrupt 1(3), interrupt 2(21), interrupt 3(20), interrupt 4(19), interrupt 5(18). These pins produce interrupts by a number of ways i.e. providing LOW value, rising or fallin...
External Interrupts:Pins 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2)can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. ...
