Struct esp32_hal::efuse::Efuse

pub struct Efuse;

Implementations

impl Efuse

pub fn get_mac_address() -> [u8; 6]

Reads chip’s MAC address from the eFuse storage.

Example

let mac_address = Efuse::get_mac_address();
writeln!(
    serial_tx,
    "MAC: {:#X}:{:#X}:{:#X}:{:#X}:{:#X}:{:#X}",
    mac_address[0],
    mac_address[1],
    mac_address[2],
    mac_address[3],
    mac_address[4],
    mac_address[5]
);

pub fn get_core_count() -> u32

Returns the number of CPUs available on the chip.

While ESP32 chips usually come with two mostly equivalent CPUs (protocol CPU and application CPU), the application CPU is unavailable on some.

pub fn get_max_cpu_frequency() -> Rate<u32, 1, 1>

Returns the maximum rated clock of the CPU in MHz.

Note that the actual clock may be lower, depending on the current power configuration of the chip, clock source, and other settings.

pub fn is_bluetooth_enabled() -> bool

Returns the CHIP_VER_DIS_BT eFuse value.

pub fn get_chip_type() -> ChipType

Returns the CHIP_VER_PKG eFuse value.

pub fn get_flash_encryption() -> bool

Get status of SPI boot encryption.
