SetString
Writes a string to the EE memory starting at the selected address.
All bytes from the string will be written including the null termination.
Parameters
- UINT Address
- Address of the value to write
- <- STRING Value
- Data string to write
- This parameter may be returned back to the caller
Return value
- This call does not return a value
GetString
Gets a string from the specified start address.
Parameters
- UINT Address
- Address of the first data byte
- BYTE MaxLength
- Maximum number of bytes in the string, also includes null termination byte
Return value
SetByteArray
Writes an array of bytes to the EE memory.
Parameters
- UINT Address
- Starting address of the first value to write
- BYTE Data
- BYTE Count
- Number of bytes to write to the EE memory, Range: 1 to 128 bytes
Return value
- This call does not return a value
SetInt
Writes a 16-bit value to the EE memory.
For consecutive 16-bit values the address must be incremented by 2.
Parameters
- UINT Address
- Address of the value to write
- UINT Value
- 16-bit value to write
- BOOL MSBFirst
- 0: LSB is the first byte, 1: MSB is the first byte
Return value
- This call does not return a value
AddressSpecificDevice
Starts a temperature conversion on a specific device using a hex string identifier.
SerialNumber parameter should be 12 characters and contain the 48-bit Serial.
Parameters
- <- STRING SerialNumber
- 48-bit Serial Number e.g. "32DF4A3C1901"
- This parameter may be returned back to the caller
Return value
- This call does not return a value
AddressNextDevice
Scans for the next connected device with a matching family code.
Goes through the device list generated by the ScanBus macro.
Parameters
- This macro has no parameters
Return value
- This call does not return a value
GetSerialString
Gets the Serial String for the current addressed device.
Parameters
- This macro has no parameters
Return value
SetLong
Writes a 32-bit value to the EE memory.
For consecutive 32-bit values the address must be incremented by 4.
Parameters
- UINT Address
- Address of the value to write
- ULONG Value
- 32-bit value to write
- BOOL MSBFirst
- 0: LSB is the first byte, 1: MSB is the first byte
Return value
- This call does not return a value
GetFloat
Reads a 32-bit floating point value starting from the specified byte address.
For consecutive float values the address must be incremented by 4.
Parameters
- INT Address
- The starting byte address
- BOOL MSBFirst
- 0: LSB is the first byte, 1: MSB is the first byte
Return value
GetLong
Reads a 32-bit value starting from the specified byte address.
For consecutive 32-bit values the address must be incremented by 4.
Parameters
- INT Address
- The starting byte address
- BOOL MSBFirst
- 0: LSB is the first byte, 1: MSB is the first byte
Return value
GetInt
Reads a 16-bit value starting from the specified byte address.
For consecutive 16-bit values the address must be incremented by 2.
Parameters
- INT Address
- The starting byte address
- BOOL MSBFirst
- 0: LSB is the first byte, 1: MSB is the first byte
Return value
GetByteArray
Reads an array of bytes starting from the selected address.
Parameters
- UINT Address
- Starting address of the first value to read
- BYTE Data
- Byte array to store incoming data
- UINT Count
- Number of bytes to read from the EE memory, Range: 1 to 128 bytes
Return value
- This call does not return a value
SetByte
Writes a single byte to the EE memory.
Parameters
- UINT Address
- Address of the value to write
- BYTE Data
Return value
- This call does not return a value
GetByte
Reads a single byte from the selected address.
Parameters
- UINT Address
- Address of the value to read
Return value
SetFloat
Writes a 32-bit floating point value to the EE memory.
For consecutive float values the address must be incremented by 4.
Parameters
- UINT Address
- Address of the value to write
- FLOAT Value
- Floating point value to write
- BOOL MSBFirst
- 0: LSB is the first byte, 1: MSB is the first byte
Return value
- This call does not return a value
Initialise
