Noduino Interrupts
来自Jack's Lab
1 Overview
- attachInterrupt()
- detachInterrupt()
- noInterrupts()
2 Examples
Use an encoder example:
- D8 connect to the channel A to receive the interrupt (rising)
- D9 connect to the channel B
#include "noduino.h"
static int32_t pos = 0;
static bool past_b = 0;
void do_encoder_a()
{
past_b = (bool)digitalRead(D9);
past_b ? pos++ : pos--;
serial_printf("pos = %d\r\n", pos);
}
void setup()
{
serial_begin(115200);
pinMode(D9, INPUT);
attachInterrupt(D8, do_encoder_a, RISING);
}
void loop()
{
}
