Arduino Giga I2C

Hi,

I have a device with an I2C adress of 0x6E. I need to send 0xDD,0X03 and then read the data returned from the device.

This is not a normal operation as Wire.h does. When I use

Wire.beginTransmission(0x6E);

Wire.write(0x03);

 Wire.endTransmission();

The arduino will send 0xDC, 0x30 to the device. Because the LSB of the address will be set as 0 when writing. This is not what I want. I want the arduino send 0xDD,0X03, where the LSB is set as 1.

The Wire.requestFrom() would set the LSB as 1 when reading. But it cannot send the registor address 0x03 after the device address.

So, anybody could advise how to handle this? I would like to send 0xDD, 0x03 and then read the response directly without sending anything else.

Many thansks!
