在ESP32-S3-DevKitM-1上学习使用按键中断，无法工作的问题？

[lymark]

硬件:ESP32-S3-DevKitM-1
IDE:Arduino IDE 2.0.3

想借助板子上的boot按钮学习使用按键外部中断控制RGB亮灭，代码附下，问题表现为开发板重启，中断无法工作。

Code: Select all

#define pushButton_pin   0
#define LED_pin   RGB_BUILTIN
 
void IRAM_ATTR toggleLED()
{
  digitalWrite(LED_pin, !digitalRead(LED_pin));
}
 
void setup()
{
  pinMode(LED_pin, OUTPUT);
  pinMode(pushButton_pin, INPUT);
  attachInterrupt(pushButton_pin, toggleLED, RISING);
}
 
void loop()
{
}

请问是不能使用该板子上的Boot按键（gpio 0）还是其他的什么问题？

只要进入到 SPI 工作模式，用 GPIO0 应该没问题的，硬件上可以确认下是这么操作的吗？或者可以说下你具体的操作步骤，然后你说重启，重启的 log 是？

当时的重启代码复制如下：

Code: Select all

另外尝试了esp32附带的按键中断示例代码：示例->ESP32->GPIO->GPIOInterrupt 代码并修改如下：

Code: Select all

#include <Arduino.h>

struct Button {
    const uint8_t PIN;
    uint32_t numberKeyPresses;
    bool pressed;
};

 Button button1 = {0, 0, false};
 Button button2 = {1, 0, false};

void ARDUINO_ISR_ATTR isr(void* arg) {
    Button* s = static_cast<Button*>(arg);
    s->numberKeyPresses += 1;
    s->pressed = true;
}

void ARDUINO_ISR_ATTR isr() {
    button2.numberKeyPresses += 1;
    button2.pressed = true;
}

void setup() {
    Serial.begin(115200);
    pinMode(RGB_BUILTIN, OUTPUT);
    pinMode(button1.PIN, INPUT_PULLUP);
    attachInterruptArg(button1.PIN, isr, &button1, FALLING);
    pinMode(button2.PIN, INPUT_PULLUP);
    attachInterrupt(button2.PIN, isr, FALLING);
}

void loop() {
    if (button1.pressed) {
        Serial.printf("Button 1 has been pressed %u times\n", button1.numberKeyPresses);
        if(button1.numberKeyPresses%2==0){neopixelWrite(RGB_BUILTIN,4,0,0);}
        if(button1.numberKeyPresses%2==1){neopixelWrite(RGB_BUILTIN,0,0,0);}
        button1.pressed = false;
    }
    if (button2.pressed) {
        Serial.printf("Button 2 has been pressed %u times\n", button2.numberKeyPresses);
        button2.pressed = false;
    }
    /*
    static uint32_t lastMillis = 0;
    if (millis() - lastMillis > 10000) {
      lastMillis = millis();
      detachInterrupt(button1.PIN);
      Serial.println(lastMillis);
    }
    */
}

正常工作了！
