EX1629 Command Set 301

vtex1629_write_teds_MLAN

FUNCTION PROTOTYPE

ViStatus vtex1629_write_teds_MLAN (ViSession vi, ViInt32 channel, ViInt32 bufferArraySize, ViInt8 _VI_FAR

buffer[]);

FUNCTION PARAMETERS

vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the

session is closed.

channels = an input integer value that specifies the channel number for the TEDS device to which the MLAN buffer

should be written. Valid input values: 0 to 47.

bufferArraySize = an input integer indicating the size of the array that holds the MLAN command bytes. Its value

should be less than VTEX1629_MAX_MLAN_DATA_LEN.

buffer[] = an input array that contains the TEDS MLAN data. Its size should be less than or equal to

VTEX1629_MAX_MLAN_DATA_LEN.

DATA ITEM RESET VALUE

Not applicable to this function.

DESCRIPTION

This function writes a variable sized block of MLAN commands and data to the TEDS EEPROM indicated by the

channel parameter. The vtex1629_read_teds_MLAN command can be used to read the response back from the

device. The commands and data in the buffer must comply with the MicroLAN specification in IEEE 1451.4-2004

Annex G.

NOTES 1) Details of the MLAN specification can be found at http://www.maxim-

ic.com/products/ibutton/applications/ and other sites.

2) The bytes returned in ‘buffer’ need to be interpreted by the application in accordance with the

MLAN specification.

EXAMPLE

ViSession instrumentHandle;

ViStatus status;

ViInt8 mlanData[VTEX1629_MAX_MLAN_DATA_LEN];

…

status = vtex1629_write_teds_MLAN (instrumentHandle,

15,

VTEX1629_MAX_MLAN_DATA_LEN,

mlanData);

If (status < VI_SUCCESS)

{

}
