class adafruit_24lc32.EEPROM(max_size: int, write_protect: bool = False, wp_pin: DigitalInOut | None = None)

Driver base for the EEPROM Breakout.

Parameters:

max_size (int) – The maximum size of the EEPROM
write_protect (bool) – Turns on/off initial write protection
wp_pin (DigitalInOut) – (Optional) Physical pin connected to the WP breakout pin. Must be a DigitalInOut object.

property write_protected: bool

The status of write protection. Default value on initialization is False.

When a WP pin is supplied during initialization, or using write_protect_pin, the status is tied to that pin and enables hardware-level protection.

When no WP pin is supplied, protection is only at the software level in this library.

property write_wraparound: bool: Determines if sequential writes will wrapaound highest memory address (len(EEPROM) - 1) address. If False, and a requested write will extend beyond the maximum size, an exception is raised.

class adafruit_24lc32.EEPROM_I2C(i2c_bus: busio.I2C, address: int = 80, write_protect: bool = False, wp_pin: DigitalInOut | None = None, max_size: int = 4096)

I2C class for EEPROM.
