Messages for using device's onboard flash filesystem functionality. This allows data to be stored persistently in the device's program flash with wear-levelling using a simple filesystem interface. The file system interface (CFS) defines an abstract API for reading directories and for reading and writing files. These are in the implementation-defined range (0x0000-0x00FF), and intended for internal-use only. Note that some of these messages share the same message type ID for both the host request and the device response.

data MsgFileioReadReq Source
SBP class for message MSG_FILEIO_READ_REQ (0x00A8).
The file read message reads a certain length (up to 255 bytes) from a given offset into a file, and returns the data in a MSG_FILEIO_READ_RESP message where the message length field indicates how many bytes were succesfully read.The sequence number in the request will be returned in the response.

data MsgFileioReadResp Source
SBP class for message MSG_FILEIO_READ_RESP (0x00A3).
The file read message reads a certain length (up to 255 bytes) from a given offset into a file, and returns the data in a message where the message length field indicates how many bytes were succesfully read. The sequence number in the response is preserved from the request.

data MsgFileioReadDirReq Source
SBP class for message MSG_FILEIO_READ_DIR_REQ (0x00A9).
The read directory message lists the files in a directory on the device's onboard flash file system. The offset parameter can be used to skip the first n elements of the file list. Returns a MSG_FILEIO_READ_DIR_RESP message containing the directory listings as a NULL delimited list. The listing is chunked over multiple SBP packets. The sequence number in the request will be returned in the response.

data MsgFileioReadDirResp Source
SBP class for message MSG_FILEIO_READ_DIR_RESP (0x00AA).
The read directory message lists the files in a directory on the device's onboard flash file system. Message contains the directory listings as a NULL delimited list. The listing is chunked over multiple SBP packets and the end of the list is identified by an entry containing just the character 0xFF. The sequence number in the response is preserved from the request.

data MsgFileioRemove Source
SBP class for message MSG_FILEIO_REMOVE (0x00AC).
The file remove message deletes a file from the file system.

data MsgFileioWriteReq Source
SBP class for message MSG_FILEIO_WRITE_REQ (0x00AD).
The file write message writes a certain length (up to 255 bytes) of data to a file at a given offset. Returns a copy of the original MSG_FILEIO_WRITE_RESP message to check integrity of the write. The sequence number in the request will be returned in the response.
