Detailed Description

template<typename SpiBlockDevice, uint8_t DieCount>
class modm::BdSpiStackFlash< SpiBlockDevice, DieCount >

SpiStack homogenoues memory.

The read(), erase(),program() and write() methodes wait for the chip to finish writing to the flash.

Template Parameters

SpiBlockDevice Base SPI block device of the homogenous stack

Author: Rasmus Kleist Hørlyck Sørensen

Member Function Documentation

template<typename SpiBlockDevice , uint8_t DieCount>

modm::ResumableResult<bool> modm::BdSpiStackFlash< SpiBlockDevice, DieCount >::erase	(	bd_address_t	address,
		bd_size_t	size
	)

Erase blocks

The state of an erased block is undefined until it has been programmed

Parameters

address	Address of block to begin erasing
size	Size to erase in bytes (multiple of read block size)

Returns: True on success

modm::ResumableResult<bool> modm::BlockDevice::erase	(	bd_address_t	address,
		bd_size_t	size
	)

inherited

Erase blocks

The state of an erased block is undefined until it has been programmed

Parameters

address	Address of block to begin erasing
size	Size to erase in bytes (multiple of read block size)

		bd_address_t	address,
		bd_size_t	size
	)

Program blocks with data

Any block has to be erased prior to being programmed

Parameters

buffer	Buffer of data to write to blocks
address	Address of first block to begin writing to
size	Size to write in bytes (multiple of read block size)

Returns: True on success

template<typename SpiBlockDevice , uint8_t DieCount>

modm::ResumableResult<void> modm::BdSpiStackFlash< SpiBlockDevice, DieCount >::waitWhileBusy ( )

This function can be used in another resumable function to wait until the flash operation is finished.

template<typename SpiBlockDevice , uint8_t DieCount>

modm::ResumableResult<bool> modm::BdSpiStackFlash< SpiBlockDevice, DieCount >::write	(	const uint8_t *	buffer,
		bd_address_t	address,
		bd_size_t	size
	)

The blocks are erased prior to being programmed

Parameters

buffer	Buffer of data to write to blocks
address	Address of first block to begin writing to
size	Size to write in bytes (multiple of read block size)

Returns: True on success

modm::ResumableResult<bool> modm::BlockDevice::write	(	const uint8_t *	buffer,
		bd_address_t	address,
		bd_size_t	size
	)

inherited
