String Initialiser component

A component allowing an easy way to initialise string variables using ROM memory. A simple and efficient way to populate string variables helping to save on RAM usage. Allows up to 16 strings to be stored. For additional strings simply use more String Initialiser components.

Downloadable macro reference

	GetString
Gets a string stored in ROM memory and loads into a RAM string variable
- BYTE	Index
Range: 0-15 Depending on number of strings
- STRING	Return

	ReadDataByte
Reads a single data byte from the specified address.
- UINT	PageAddress
Address bits A23-A8 : 16-bit Address - Range 0x0000 - 0xFFFF
- BYTE	ByteAddress
A7-A0 : 8-bit Address within the page - Range 0x00 - 0xFF
- BYTE	Return

	ReadUniqueID
Reads the 8-byte unique identifier from the IC. Useful if you need each board to have it's own guarenteed unique address or identifier.
- BYTE	ID
8-Byte data array to store the unique ID read back from the IC.
- VOID	Return

	WriteDataArray
Writes an array of data bytes atarting at the specified address. Writes must be enabled and memory locations must be erased for data writes to function correctly. Note that all bytes will be written to the same page.
- UINT	PageAddress
Address bits A23-A8 : 16-bit Address - Range 0x0000 - 0xFFFF
- BYTE	ByteAddress
A7-A0 : 8-bit Address within the page - Range 0x00 - 0xFF
- BYTE	Count
Number of bytes to write.
- BYTE	Data
- VOID	Return

	EraseChip
Erases all data stored on the chip. Chip erase takes between 20 seconds and 100 seconds to complete. Blocking mode is recommended to ensure write cycle is complete.
[[File:]] -	Blocking
Controls if the macro blocks until the erase cycle is complete. 0 = Don't Wait, 1 = Wait
- VOID	Return

	WriteDataByte
Writes a single data byte to the specified address. Writes must be enabled and memory locations must be erased for data writes to function correctly.
- UINT	PageAddress
Address bits A23-A8 : 16-bit Address - Range 0x0000 - 0xFFFF
- BYTE	ByteAddress
A7-A0 : 8-bit Address within the page - Range 0x00 - 0xFF
- BYTE	Data
Data byte to write
- VOID	Return

	EraseBlock
Erases a block of data stored on the chip. Erase takes between 45 milliseconds and 2000 milliseconds to complete. Blocking mode is recommended to ensure write cycle is complete.
- BYTE	EraseMode
0=4KB / 1=32KB / 2=64KB
- UINT	PageAddress
Address bits A23-A8 : 16-bit Address - Range 0x0000 - 0xFFFF
[[File:]] -	Blocking
Controls if the macro blocks until the erase cycle is complete. 0 = Don't Wait, 1 = Wait
- VOID	Return

	ReadDataArray
Reads up to 256 data bytes starting from the specified address. Note that all bytes will be read from the same page.
- UINT	PageAddress
Address bits A23-A8 : 16-bit Address - Range 0x0000 - 0xFFFF
- BYTE	ByteAddress
A7-A0 : 8-bit Address within the page - Range 0x00 - 0xFF
- BYTE	Count
Number of bytes to read.
- BYTE	Data
Byta array to store the incoming read data.
- VOID	Return

	Initialise
Initialises the SPI bus ready for communications.
- VOID	Return

	Initialise
Configures each matching sensor on the bus with the specified conversion bits.
- VOID	Return

	SendBinaryFloat
Sends out a 32-bit binary floating point value split across four bytes.
[[File:]] -	Value
[[File:]] -	MSBfirst
0=Least significant byte first, 1=Most significant byte first
- VOID	Return

	GetProp
Allows the property filter for the COM port list to be copied to a parent component.
- STRING	PropName
- STRING	Return

	ReceiveByteArray
Attempts to receive an array of bytes using the COM port Returns the number of bytes received.
- BYTE	Data
- UINT	MaxLength
Max number of bytes to try and read
- UINT	Timeout
Time to wait for incoming data in milliseconds
- UINT	Return

	ReceiveString
Attempts to receive an string using the COM port Returns the number of bytes received.
- UINT	Timeout
Time to wait for incoming data in milliseconds
- UINT	MaxLength
Max number of bytes to try and read
- STRING	Return

	PWMEnable
Allows pulse width modulated transistor outputs to be switched on or off. Bit 0 = Enable AB Bit 1 = A / Bit 2 = B Bit 3 = C / Bit 4 = D Bit 5 = Enable CD
- BYTE	EnableMask
Range 0-63 or 0b00000 to 0b111111
- VOID	Return

	Initialise
- VOID	Return

	GetProp
Allows the property filter for the COM port list to be copied to a parent component.
- STRING	PropName
- STRING	Return
