Detailed Description

Non-uniform memory access.

The ATmega32U4 has SRAM, flash and EEPROM to store data. In case dynamic information is mixed with static, perhaps device specific, information, a single interface is provided to access these different parts of the microcontroller's memory space.

Enumeration Type Documentation

memspace_t

enum memspace_t

Define which memory space the body of a data block is in.

Enumerator
MEMSPACE_RAM	RAM storage.
MEMSPACE_PROGMEM	Flash (or program memory) storage.
MEMSPACE_EEPROM	EEPROM storage.
MEMSPACE_NONE	Placeholder if the refering entity only provides metadata.

Function Documentation

memcpy_memspace()

void* memcpy_memspace	(	enum memspace_t	memspace,
		void *restrict	dest,
		const void *restrict	src,
		size_t	length
	)

Generic memcpy function that calls the correct copy routine depending on the provided memory space.
