IBlockDriver Interface

Namespace: GHIElectronics.TinyCLR.IO.TinyFileSystem · Assembly: GHIElectronics.TinyCLR.IO.TinyFileSystem

Interface to abstract the file system from the physical device.

public interface IBlockDriver : IDisposable

Properties

int DeviceSize { get; }

Full capacity of the device in bytes.

int SectorSize { get; }

The size in bytes of a sector on the device.

ushort ClusterSize { get; }

The cluster size in bytes.

void EraseChip()

Completely erases the memory chip (fills it with 0xFF, in reality, as it is a Flash memory).

void EraseSector(int sectorId)

Erases a sector on the device.

Parameter	Type	Description
`sectorId`	`int`	Sector to be erased.

void Read(ushort clusterId, int clusterOffset, byte[] data, int index, int count)

Read a block of data from a cluster.

Parameter	Type	Description
`clusterId`	`ushort`	The cluster to read from.
`clusterOffset`	`int`	The offset into the cluster to start reading from.
`data`	`byte[]`	The byte array to fill with the data read from the device.
`index`	`int`	The index into the array to start filling the data.
`count`	`int`	The maximum number of bytes to read.

void Write(ushort clusterId, int clusterOffset, byte[] data, int index, int count)

Write a block of data to a cluster.

Parameter	Type	Description
`clusterId`	`ushort`	The cluster to write to.
`clusterOffset`	`int`	The offset into the cluster to start writting to.
`data`	`byte[]`	The byte array containing the data to be written.
`index`	`int`	The index into the array to start writting from
`count`	`int`	The number of bytes to write.
