Struct esp32c2_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_flash_encryption() -> bool

Get status of SPI boot encryption.

pub fn get_rwdt_multiplier() -> u8

Get the multiplier for the timeout value of the RWDT STAGE 0 register.

pub fn get_block_version() -> (u8, u8)
