cu64

Device In

Device # Identification

cerrcodeclst

error in (no error)

error in can accept error information wired from VIs previously called.

cbool

status

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

ci32

code

code is the error or warning code.

Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

cstr

source

source describes the origin of the error or warning.

Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

ci32

address

The address of the I2C device

cstr

I2CPacketString

Specify the bytes of your I2C packet using 's' for start, 'R' for read, 'T' for write, and 'p' for stop. Only one stop condition per call is supported.

For example, if you wanted to write two bytes, generate a repeat start, write one more byte, then read three bytes, the string would be "sTTsTsRRRp".

You can also use numbers to indicate the number of bytes, e.g. "sT2sTsR3p"

c1du8

data

The entire set of data to send, in order from first to last. The length of this data must match the total number of bytes specified to be sent in the I2CPacketString.

cu8

Numeric

Data bytes

iu64

Device Out

Same as Device In

ierrcodeclst

error out

error out passes error or warning information out of a VI to be used by other VIs.

ibool

status

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

Right-click the error out control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

ii32

code

code is the error or warning code.

Right-click the error out control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

istr

source

source describes the origin of the error or warning.

Right-click the error out control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

i1du8

recvData

The received data. This will be made up of all 'R' bytes as specified in the I2CPacketString, in order from first to last.

iu8

Data bytes

ii32

recvDataLen

Specifies the length of the recvData array. Returns the number of bytes recieved. If the received data is longer than the recvData array, an error will be thrown. Any error detected in the received data will result in this argument becoming 0.
