在Arduino Uno上,有三个可用的PCINT引脚组,分别是PCINT0、PCINT1和PCINT2。每个组包含多个引脚,可以通过设置相应的寄存器来启用或禁用中断。 具体来说,以下是Arduino Uno上的"pin change"中断相关的引脚和寄存器: PCINT0引脚组(对应引脚D8-D13): PCINT0:包括引脚D8-D13,对应寄存器PCMSK0。 PCINT0_...
因为Arduino UNO有三个端口,因此有三个 中断服务函数,其名称如下图所示: ISR(PCINT0_vect) { ...(函数程序) } 1. 2. 3. 4. 示例 电路图如图所示,尝试实现第一次按下按键BUTTON时,板上的LED灯点亮,再次按下时,LED灯熄灭,如此往复。 volatile int a = 0; void count() { a = 1 - a; } void...
It is e.g. hard to grasp why you enable pin 1 and 11 (isn’t that what “PCMSK0 |= 0b00000001; // PCINT0 and PCMSK1 |= 0b00001000; // PCINT11 ” does?) and then define routines ISR(PCINT0_vect) and ISR(PCINT1_vect), why PCINT1_vect and not PCINT11_vect? You mak...
