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 sends a restart condition between the write and read operations.

public:
 void WriteRead(Platform::Array <byte> ^ writeBuffer, Platform::Array <byte> ^ readBuffer);

void WriteRead(winrt::array_view <byte> const& writeBuffer, winrt::array_view <byte> & readBuffer);

public void WriteRead(byte[] writeBuffer, byte[] readBuffer);

function writeRead(writeBuffer, readBuffer)

Public Sub WriteRead (writeBuffer As Byte(), readBuffer As Byte())

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.

Remarks

Error Codes

0x80070002

The bus address was not acknowledged.

0x8007045D

The I² C device negatively acknowledged the data transfer before the entire buffer was read.
