// Location of true interrupt pins: // Uno: pins 2 and 3 // Mega 2560: pins 2, 3, 21, 20, 19, and 18 // Since there are only 6 true interrupt pins, use Good Performance if there are 4 motors // Bugs for a parti
Arduino Unois a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everyth...

Different types of Arduino board have different numbers of interrupts pins e.g. Arduino UNO have two interrupt ports and Arduino Mega2560 have six interrupt ports named as INT1,INT0. On the software side create sleep mode for Arduino and use a timer base interrupts which would internally be e...
2) 外部中断,外部触发中断,UNO的2,3号端口可以触发中断 一、外部中断学习 1、Arduino 开发板的外部中断引脚 带中断的数字引脚 attachInterrupt()的第一个参数是中断号。 通常,您应该使用digitalPinToInterrupt(pin)将实际的数字引脚转换为特定的中断号。 例如,如果连接到引脚3,则使用digitalPinToInterrupt(3)作为attach...
1. 连接上Arduino UNO开发板 查看连接的端口号: 选择开发板型号: 2. 选择烧录指定的程序 如果手上有支持蓝牙的或者WIFI的 Arduino开发板可以选择其对应的固件示例代码进行烧录。这里只演示Arduino UNo开发板,所以选择StandardFirmata此示例。 除了StandardFirmata也可以选择StandardFirmataPlus,与标准版的固件不同的地方是...
2– Choose Which Pins to Interrupt I know I said earlier that a change on any of the pins in a port would trigger the port’s ISR, but that is true only when you turn that particular pin on. This is down with what is called a mask. Since the ATMEGA328 has 3 ports, it also ha...
Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset bu...
(using DA Mellis' support files). The library enables you to assign an interrupt to pins on your chip that support them, and presents a common interface to all supported chips. This means that on the Arduino Uno and Mega you don't give it an interrupt number, as perhttp://arduino.cc...
例如,在Arduino UNO上: Timer0– 用于 millis(), micros(), delay() and PWM 在 pins 5 和 6Timer1– 用于 Servos, the WaveHC library and PWM 在 pins 9 &和10Timer2– 用于 Tone and PWM 在 pins 11 和 13 共享数据安全 由于中断将挂起处理器处理中断所做的任何事情,因此我们必须小心在中断处理...
