FullTransfer FullTransfer FullTransfer FullTransfer

The data was entirely transferred. For WriteReadPartial, the data for both the write and the read operations was entirely transferred.

For this status code, the value of the I2cTransferResult.BytesTransferred member that the method returns is the same as the size of the buffer you specified when you called the method, or is equal to the sum of the sizes of two buffers that you specified for WriteReadPartial.

PartialTransfer PartialTransfer PartialTransfer PartialTransfer

The I2 C device negatively acknowledged the data transfer before all of the data was transferred.

For this status code, the value of the I2cTransferResult.BytesTransferred member that the method returns is the number of bytes actually transferred. For WriteReadPartial, the value is the sum of the number of bytes that the operation wrote and the number of bytes that the operation read.

SlaveAddressNotAcknowledged SlaveAddressNotAcknowledged SlaveAddressNotAcknowledged SlaveAddressNotAcknowledged

The bus address was not acknowledged.

For this status code, the value of the I2cTransferResult.BytesTransferred member that the method returns of the method is 0.
