led sample for maix-bit

    if(fpioa_set_function(number, FUNC_GPIO3) < 0){
        return 0;
    }
    gpio_init();
    gpio_set_drive_mode(3, GPIO_DM_OUTPUT);
    gpio_pin_value_t value = GPIO_PV_HIGH;
    gpio_set_pin(3, value);
    printf("try led fin %d \n", number);
    while (1)
    {
        gpio_set_pin(3, value = !value);
        sleep(1);
    }

number should be

• 12 : blue
• 13 : green
• 14 : red
