        Temporarily, WiFi and BT stacks can not be used at the same time.
        Select which stack to enable.

config MEMMAP_BT
    bool
    depends on ESP32_ENABLE_STACK_BT
    help
        The Bluetooth stack uses memory that cannot be used as generic memory anymore. This
        reserves the space for that within the memory map of the compiled binary.
        This option is required to enable BT stack.
        Temporarily, this option is not compatible with WiFi stack.

config MEMMAP_SMP
    bool "Reserve memory for two cores"
    default "y"
    help
        The ESP32 contains two cores. If you plan to only use one, you can disable this item
        to save some memory. (ToDo: Make this automatically depend on unicore support)

config MEMMAP_TRACEMEM
    bool "Use TRAX tracing feature"
    default "n"
    help
        The ESP32 contains a feature which allows you to trace the execution path the processor
        has taken through the program. This is stored in a chunk of 32K (16K for single-processor)
        of memory that can't be used for general purposes anymore. Disable this if you do not know
        what this is.

config MEMMAP_SPISRAM
    bool "Use external SPI SRAM chip as main memory"
    default "n"
    help
        The ESP32 can control an external SPI SRAM chip, adding the memory it contains to the 
        main memory map. Enable this if you have this hardware and want to use it in the same
        way as on-chip RAM.

config WIFI_ENABLED
    bool
    default "y"
    depends on ESP32_ENABLE_STACK_WIFI
    help
        This compiles in the low-level WiFi stack.

		Temporarily, this option is not compatible with BT stack.

config SYSTEM_EVENT_QUEUE_SIZE
    int "System event queue size"
    default 32
    help
        Config system event queue size in different application.

config SYSTEM_EVENT_TASK_STACK_SIZE
    int "Event loop task stack size"
    default 2048
    help
        Config system event task stack size in different application.


config MAIN_TASK_STACK_SIZE
    int "Main task stack size"
    default 4096
    help
        Config system event task stack size in different application.


config NEWLIB_STDOUT_ADDCR
	bool "Standard-out output adds carriage return before newline"
	default y
	help
		Most people are used to end their printf strings with a newline. If this
		is sent as is to the serial port, most terminal programs will only move the
		cursor one line down, not also move it to the beginning of the line. This
		is usually done by an added CR character. Enabling this will make the
		standard output code automatically add a CR character before a LF.
