Edit

Performs an atomic operation to write data to and then read data from the inter-integrated circuit (I² C) bus on which the device is connected, and returns information about the success of the operation that you can use for error handling.

public:
 virtual I2cTransferResult WriteReadPartial(Platform::Array <byte> ^ writeBuffer, Platform::Array <byte> ^ readBuffer) = WriteReadPartial;

I2cTransferResult WriteReadPartial(winrt::array_view <byte> const& writeBuffer, winrt::array_view <byte> & readBuffer);

public I2cTransferResult WriteReadPartial(byte[] writeBuffer, byte[] readBuffer);

function writeReadPartial(writeBuffer, readBuffer)

Public Function WriteReadPartial (writeBuffer As Byte(), readBuffer As Byte()) As I2cTransferResult

Parameters

writeBuffer: Byte[]

byte[]

A buffer that contains the data that you want to write to the I² C device. This data should not include the bus address.

readBuffer: Byte[]

byte[]

The buffer to which you want to read the data from the I² C bus. The length of the buffer determines how much data to request from the device.

Returns

I2cTransferResult

A structure that contains information about whether both the read and write parts of the operation succeeded and the sum of the actual number of bytes that the operation wrote and the actual number of bytes that the operation read.
