  • I2C_ReadBurst

    The function I2C_ReadBurst reads a number of iNumberBytes from a i2c-device specified with uSlaveAddress.

    int I2C_ReadBurst( UCHAR uSlaveAddress, UCHAR* pBuffer, UCHAR ucOffset, WORD iNumberBytes ); int i2c_BurstRead( UCHAR uSlaveAddress, UCHAR* pBuffer, UCHAR ucOffset, WORD iNumberBytes );

    Parameters

    uSlaveAddress
    Slave-Address of the i2c-device.

    pBuffer
    Buffer to receive data.

    ucOffset
    Offset at where to begin with data-read. This is also the offset, where data will be written to pBuffer.

    iNumberBytes
    Number of bytes to read.

    Return Values

    Returns 0 if succesful.

    Remarks

    Issues following sequence:

    • Lock

    • Start

    • SlaveAddress with write-bit

    • ucOffset

    • SlaveAddress with read-bit

    • Read specified number of bytes

    • Stop

    • Unlock

    This function calls I2C_Lock and I2C_Unlock to prevent multiple accesses to the i2c-bus. Don't lock access to i2c-bus prior to using this function!!
