Controls the I2C data that is subject to the selected I2C operation.
If I2COperationSelector is set to "Read", I2CTransmitBuffer returns the data read from the I2C device after I2COperationExecute was executed.
If I2COperationSelector is set to "Write", I2CTransmitBuffer controls the data that will be sent to the I2C device when I2COperationExecute is executed.

Code example

C++

// Get Transmit buffer as register node
auto nodeTransmitBuffer = nodeMapRemoteDevice->FindNode<vapinamespace::core::nodes::RegisterNode>("I2CTransmitBuffer");
// Write the I2CTransmitBuffer
const std::array<uint8_t, 16> i2cData = { 0x59, 0x6F, 0x75, 0x20, 0x66, 0x6F, 0x75, 0x6E, 0x64, 0x20, 0x6D, 0x65, 0x21, 0x21, 0x21, 0x00 };
nodeTransmitBuffer->Write(i2cData.data(), i2cData.size());
// Read the I2CTransmitBuffer
const auto len = nodeTransmitBuffer->Length();
const auto data = nodeTransmitBuffer->Read(len);

C#

// Get Transmit buffer as register node
var nodeTransmitBuffer = nodeMapRemoteDevice.FindNode<peak.core.nodes.RegisterNode>("I2CTransmitBuffer");
// Write the I2CTransmitBuffer
ByteCollection byteCollection = new ByteCollection(
  new byte[]{ 0x59, 0x6F, 0x75, 0x20, 0x66, 0x6F, 0x75, 0x6E, 0x64, 0x20, 0x6D, 0x65, 0x21, 0x21, 0x21, 0x00 });
nodeTransmitBuffer.Write(byteCollection);
// Read the I2CTransmitBuffer
uint len = nodeTransmitBuffer.Length();
byte[] data = nodeTransmitBuffer.Read(len).ToArray();

Python

# Get Transmit buffer as register node
node_transmit_buffer = nodemap_remote_device.FindNode("I2CTransmitBuffer")
# Write the I2CTransmitBuffer
data = ids_peak.VectorUInt8([0x59, 0x6F, 0x75, 0x20, 0x66, 0x6F, 0x75, 0x6E, 0x64, 0x20, 0x6D, 0x65, 0x21, 0x21, 0x21, 0x00])
node_transmit_buffer.Write(data)
# Read the I2CTransmitBuffer
data_len = node_transmit_buffer.Length()
data = node_transmit_buffer.Read(data_len)
