| ====== EEWrite ====== | ====== EEWrite ====== |
| |
| Write bytes into per-''address'' backing files named like _ee_0000. | Write data to non-volatile memory. |
| | |
| | This feature is supported only on models with built-in FRAM. |

| ===== Syntax ===== | ===== Syntax ===== |
| |
| * **address**: EEPROM ''address'' (0 to 4095). | * **address**: EEPROM ''address'' (0 to 4095). |
| * **data**: Integer, float, bytes, or bytearray value to write. | * **data**: ''int'', ''float'', ''bytes'', or ''bytearray'' value to write. |
| * **byteLength**: Number of bytes to write. Must be positive and remain within the EEPROM bounds. ''Float'' writes require 4. Bytes and bytearray writes use the first ''byteLength'' bytes. | * **byteLength**: Number of bytes to write. Must be positive and remain within the non-volatile memory's bounds. ''Float'' writes require 4. ''bytes'' and ''bytearray'' writes use the first ''byteLength'' bytes. |

| ===== Exceptions ===== | ===== Exceptions ===== |

| * [[https://docs.micropython.org/en/latest/library/builtins.html#TypeError|TypeError]]: ''address'', ''data'', or ''byteLength'' is invalid. | * [[https://docs.micropython.org/en/latest/library/builtins.html#TypeError|TypeError]]: ''address'', ''data'', or ''byteLength'' is invalid. |
| * [[https://docs.micropython.org/en/latest/library/builtins.html#ValueError|ValueError]]: ''address'' or ''byteLength'' is out of range, the write would extend past ''address'' 4095, a float write was requested with a ''byteLength'' other than 4, a float is not representable as a 32-bit value, or ''byteLength'' exceeds the source bytes length. | * [[https://docs.micropython.org/en/latest/library/builtins.html#ValueError|ValueError]]: ''address'' or ''byteLength'' is out of range, the write would extend past ''address'' 4095, a ''float'' write was requested with a ''byteLength'' other than 4, a ''float'' is not representable as a 32-bit value, or ''byteLength'' exceeds the source bytes length. |
