FTDI (FT800) component

The FT800 provides a powerful feature set in a small package to create dynamic HMI interfaces. The device supports line by line graphics rendering to 1/16 of a pixel on displays with resolution up to 512 x 512 with 262K colours. The chip includes a touch controller for sensing touch feedback from a TFT display with a resistive touch panel as well as a sound synthesizer and audio playback with a PWM output to drive a speaker.

- BYTE	Command
- VOID	Return

	MemWrite32
Writes a unsigned long value to the FT800 internal address space
- ULONG	Address
- ULONG	Data
- VOID	Return

	Initialise
System initialization routines. Executed once on reset. Returns 0 if device not detected or 1 if device is correctly initialised.
- 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
- BYTE	Return

	AppendStringToFile
- STRING	Data_String
- BYTE	Return

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

	SetByte
- ULONG	Int
- BYTE	Ix
- BYTE	Value
- VOID	Return

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

	GetByte
Gets a byte from an int
- ULONG	Int
- BYTE	Ix
- BYTE	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
