	SampleSensor
Reads the touch controller and returns true if there is currently a touch in progress. The touch coordinates can be read using the ReadCoord macro. Return 0 = No Touch, 1 = Single touch detected, 2 = Two touch points detected
- BYTE	Return

	ReadCoord
Reads a coordinate returned from the Sample Sensor macro. Coordinate is scaled to the X/Y Pixel bounds specified.
- BYTE	Coordinate
0 = X, 1 = Y, 2 = Pressure
- BYTE	Index
Touch Index Range: 0 - 1
- UINT	Return

	Initialise
Activates the SPI peripheral and claims control over the I/O pins.
- VOID	Return

	CreateFile
- STRING	Filename
- BYTE	Return

	OpenFolder
- STRING	Folder_Name
- 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

	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

	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

	Properties
	Channel
Channel selection
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.

	Connections
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	Simulations
	Label
Label used to identify the component on the panel.
	Scope Traces
Selects if the component pin connections are automatically generated on the data recorder window or not. Yes: Automatically add the component pins to a group on the data recorder which will reflect the sim data during simultion. No: Do not show the pin signals on the data recorder window.
	Console Data
Selects if the console data is automatically generated or not
	API
Specifies the API component on the panel to interact with to provide comms simulation.
