I2CData is an Integer register limited to 32 bits. If I2CDataLength is > 4 bytes, this register cannot be used. Use the new I2CTransmitBuffer node instead. I2CData is present only for backward compatibility. New implementations should use I2CTransmitBuffer. |
Controls the I2C data that is subject to the selected I2C operation.
If I2COperationSelector is set to "Read", I2CData returns the data read from the I2C device after I2COperationExecute was executed.
If I2COperationSelector is set to "Write", I2CData controls the data that will be sent to the I2C device when I2COperationExecute is executed.

Code example
C++
// Determine the current I2CData
int64_t value = nodeMapRemoteDevice->FindNode<peak::core::nodes::IntegerNode>("I2CData")->Value();
// Set I2CData to 0xAB
nodeMapRemoteDevice->FindNode<peak::core::nodes::IntegerNode>("I2CData")->SetValue(0xAB);
C#
// Determine the current I2CData
long value = nodeMapRemoteDevice.FindNode<peak.core.nodes.IntegerNode>("I2CData").Value();
// Set I2CData to 0xAB
nodeMapRemoteDevice.FindNode<peak.core.nodes.IntegerNode>("I2CData").SetValue(0xAB);
Python
# Determine the current I2CData (int)
value = nodeMapRemoteDevice.FindNode("I2CData").Value()
# Set I2CData to 0xAB (int)
nodeMapRemoteDevice.FindNode("I2CData").SetValue(0xAB)
