Chips are all the chips we know about. Note that the test assumes that SST25VF016B is first.

Types

type Chip

type Chip struct {
	Vendor      string
	Chip        string
	ID          ID
	ArraySize   int64
	PageSize    int64
	SectorSize  int64
	BlockSize   int64
	Is4BA       bool
	EraseBlocks []EraseBlock

	WriteEnableInstructionRequired bool
	WriteEnableOpcodeSelect        op.OpCode
	Write                          op.OpCode
	Read                           op.OpCode
}

Chip defines a chip.

func Lookup

func Lookup(id ID) (*Chip, error)

Lookup finds a Chip by id, returning os.ErrNotExist if it is not found.

func (*Chip) String

func (c *Chip) String() string

String implements string for Chip.

type EraseBlock

type EraseBlock struct {
	Size int
	Op   op.OpCode
}

EraseBlock defines the size and the opcode used for an erase block. In Flash Chips, the erase region is aligned to the size.

type ID

type ID int
