MCP23017 Example throws an error when using interrupts about esp-idf-lib HOT 2 CLOSED

Yes, in the example there is a bug in the interrupt handler.
You cannot call printf() directly from an interrupt handler. Instead, you need to use either the FreeRTOS queue or event groups. You can see how to do this correctly in the example for tca95x5.

I'm leaving this issue open until I fix the bug in the mcp23017 example.

Thank you. I think, my question is closed. I use code like this

static void IRAM_ATTR intr_handler(void *arg)
{

    if (!interrupt_running)
    {
        interrupt_running = true;
        xTaskCreate(read_interrupt, "read_interrupt", configMINIMAL_STACK_SIZE * 6, NULL, 5, NULL);
    }
}

and if I need to print - I use ESP_DRAM_LOGx functions
