Macro reference

ReceiveByte

	ReceiveByte
Receives a byte from the one wire bus a bit at a time
- BYTE	Return

TransmitByte

	TransmitByte
Transmit a byte to the one wire bus a bit at a time
- BYTE	Command

- VOID	Return

SkipROM

	SkipROM
Performs a bus reset and the sends the SkipROM command byte
- VOID	Return

BusReset

	BusReset
Issue a 'ping' on the bus. If there is at least one sensor on the bus then it will generate a presence pulse. Returns 0 if a presense pulse was detected Returns 1 no device was detected
- BOOL	Return

- VOID	Return

ScanBus

	ScanBus
Scans the one wire bus to detect all connected devices. Returns the number of one wire devices found.
- BYTE	Return

GetDeviceCount

	GetDeviceCount
Returns the number of devices found by the last ScanBus operation.
- BYTE	Return

GetIDByte

	GetIDByte
Returns byte ectet of the 64-Bit lasered ROM code, 255 on error
- BYTE	Device
Device ID - Range: 0 - NumDevices - 1
- BYTE	ByteIndex
Index of the data byte. 0=FamilyCode, 1-6=Serial, 7=CRC
- BYTE	Return

Initialise
