• Hiya,

    I have this simple piece of code:

    console.log('HELLO');
    console.log(process.memory());
    
    pinMode(D16, 'input_pullup');
    pinMode(D17, 'input_pullup');
    pinMode(D18, 'input_pullup');
    pinMode(D19, 'input_pullup');
    
    console.log(process.memory());
    
    const options = {
      repeat: true,
      debounce: 100
    };
    
    setWatch(e => {
      //{state:bool, time:float, lastTime:float}
      const state = e.state;
      console.log('D16 -> state:', state);
      console.log(process.memory());
    }, D16, options);
    
    setWatch(e => {
      //{state:bool, time:float, lastTime:float}
      const state = e.state;
      console.log('D17 -> state:', state);
      console.log(process.memory());
    }, D17, options);
    
    setWatch(e => {
      //{state:bool, time:float, lastTime:float}
      const state = e.state;
      console.log('D18 -> state:', state);
      console.log(process.memory());
    }, D18, options);
    
    setWatch(e => {
      //{state:bool, time:float, lastTime:float}
      const state = e.state;
      console.log('D19 -> state:', state);
      console.log(process.memory());
    }, D19, options);
    
    

    Randomly when one of the buttons is pressed I get this error:

    >Guru Meditation Error: Core  0 panic'ed (StoreProhibited). Exception was unhandled.

    And it just goes into a loop and keeps printing this out. Using this Firmware: espruino_2v18_esp32

    Any ideas?

  • If i change the code to this:

    setInterval( () => {
      if(digitalRead(D16) == 0) {
        console.log('D16');
      }
      if(digitalRead(D17) == 0) {
        console.log('D17');
      }
      if(digitalRead(D18) == 0) {
        console.log('D18');
      }
      if(digitalRead(D19) == 0) {
        console.log('D19');
      }
    }, 100);
    

    The error goes away

  • I'm having the exact same problem - using setWatch on the ESP32 sometimes reboots when one of the buttons is pressed.

    I think this is something to do with how GPIO interrupts the handled by gpio_intr_handler (in jshardware.c) - the code does not disable further interrupts and might be invoked again while processing (buttons generate a lot of interrupts when switching from one state to another, this is why debouncing is needed).

  • Seems like there is an open issue for this:
    https://github.com/espruino/Espruino/iss­ues/2342

  • I'm experiencing the same problem that we've encountered in the past.

  • if you have the .elf file you can use use

    https://maximeborges.github.io/esp-stack­trace-decoder/

    upload .elf file and enter the Stack trace CPU wise to get detail about the function
