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 falling edge or changing value to the interrupt pins.
一共四组串口。其中Serial0也被连接到 Tmega16U2 USB-to-TTL Serial 芯片(上文有介绍,我们USB连接电脑用的就是这个串口)。RX接收数据,TX传输数据。 External Interrupts(外部中断): 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), 21 (interrupt 2)。 ...
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, ...

External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). These pins can be configured to trigger an interrupt on a low level, a rising or falling edge, or a change in level. See theattachInterrupt()functio...
wokwi-arduino-mega参考 Arduino Mega 2560。由ATmega2560芯片提供支持,该芯片拥有256K字节的Flash程序内存、8k字节的SRAM和4K字节的EEPROM。该板具有54个数字引脚、16个模拟输入引脚和4个串行端口。它以16MHz运行。 引脚名称 引脚0到53是数字GPIO引脚。引脚A0至A15除了是数字GPIO引脚外,还兼作模拟输入引脚。
that on the Arduino Uno and Mega you don't give it an interrupt number, as perhttp://arduino.cc/en/Reference/attachInterrupt. Rather, your first argument is a pin number of a pin that's supported on that chip (seehttps://github.com/GreyGnome/EnableInterrupt/wiki/Usage#pin--port-...
Arduino Mega 2560是基于ATmega2560的微控制板，有54路数字输⼊/输出端⼝(其中15个可以作为PWM输出)，16路模拟输⼊端⼝，4路UART串⼝，16MHz的晶振，USB连接⼝，电池接⼝，ICSP头和复位按钮。简单地⽤USB连接电脑或者⽤交直流变压器就能使⽤。 Mega 2560 是Arduino Mega系列的升级版。Mega 256...
