	AssignLogo
Sets the logo displayed on the indicator.
- BYTE	LogoIdx
Logo Index: 1=Tick, 2=Cross, 3=Exclamation, 4=Green, 5=Amber, 6=Red, 7=Stop, 8=Go
- VOID	Return

	SetRange
Set the minimum and maximum values of the scale
[[File:]] -	Minimum
Minimum value for the scale
[[File:]] -	Maximum
Maximum value for the scale
- VOID	Return

	ReadByteFromIndex
Reads an arbitrary byte of data from the current open file. Return = Data byte read from the local sector buffer. Experimental and potentially slow if navigating backwards through the file.
- ULONG	Address
Contains the position of the byte to be read from the file
- BYTE	Return

	CreateFile
Creates a file in the current folder location on the card. Default = Root Returns 0 for success File must be opened using "Open_File" after creation before writing any data.
- STRING	Filename
8.3 format filename e.g."file.txt"
- BYTE	Return

	ScanCurrentFolder
Method for retreiving file or folder names for the card to allow for dynamic file opening or playback. Does not currently simulate. 0 - Filetype found and stored into string array, 1 - End of folder reached, 2 - Filetype mismatch 3 - Empty
- UINT	Current_Idx
Contains the current pointer in the directory table. Values from 0 to 511 to completley search the current folder for a files or folders
- BYTE	Scan_Type
Sets the scan to search for Files or Folders. 0 = Scan for files, 1 = Scan for folders
- BYTE	Return

	ReadByteFromScan
Returns a byte of the name of the file or folder retreived from the Scan_Current_folder function. Return = ASCII byte at position Idx from the folder name or file name at position Current_Idx in the directory
- BYTE	idx
0 - 11 for a file, 0 - 7 for a folder
- BYTE	Return

	OpenFolder
".." - Jumps up a directory, if at root then remains in root "root" - Jumps directly back to the root directory "foldername" - Opens folder named foldername
- STRING	Folder_Name
- BYTE	Return

	ReadByteFromBuffer
Reads a byte of data from the local sector buffer. Return = Data byte read from the local sector buffer.
- UINT	Address
0 - 511 - Contains the position of the byte to be read
- BYTE	Return

	ReadFileLength
Returns the number of bytes in the current sector that are used by the current open file. Return = 512 - Sector is filled with file data Return < 512 - Last sector of the file, Retval specifies how many bytes of data are remaining in the sector
[[File:]] -	Return

	OpenFile
Searches for and opens a file for reading or writing from within the current directory on the disk. Returns 0 for success.
- STRING	Filename
8.3 filename of the file we are trying to open e.g. "file.txt"
- BYTE	Return

	WriteFileSector
Overwrites the current sector on the memory card with the contents of the local sector buffer. See write_byte_to_buffer function. Return = 0 - File sector written successfully. Return > 0 - File sector write error
- BYTE	Return

	SetFileIndex
Sets the current file index and used to switch between several open file streams. Default = 0.
- BYTE	File_Index
File index ranges from 0 to (Max Concurrent Files - 1)
- VOID	Return

	AppendStringToFile
Adds the contents of the data string parameter to the end of the currently open file. Returns 0 for success.
- STRING	Data_String
Data to append to the end of the file
- BYTE	Return

	ReadFileSize
Reads the entire size of the current file in bytes.
- ULONG	Return

	SetTimeAndDate
Sets the current time and date. Time = (Hour << 11) + (Min << 5) + (Sec >> 1) Date = (YearFrom1980 << 9) + (Month << 5) + (Day) Additional details can be found here: http://www.maverick-os.dk/FileSystemFormats/FAT16_FileSystem.html#TimeFormat
- UINT	Time
Sets the current Time in FAT Time format hhhhhmmmmmmsssss - S=Secs/2
- UINT	Date
Sets the current Date in FAT Date format yyyyyyymmmmddddd - Y=Years since 1980
- VOID	Return

	Initialise
Attempts to communicate with the SD card and if successful sets up the file system. Returns 0 for success.
- BYTE	Return

	Initialise
Initialise the comms to the Arduino board ready for commands to be sent.
- VOID	Return
