<p class=MsoNormal>Hi,<o:p></o:p></p>

<p class=MsoNormal>I am trying to send 8 bit register address using i2c_transfer.My

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Where the register address ” reg” is for
example 0x08. I want to read a 8bit register address 0x08. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My confusion is that <b>since i2c_msg structure has
u16 is it possible to send 0x08.Will I need to send as 0x0008.</b><o:p></o:p></p>
