Hi all,

 

I have an ATMega328P and trying to use the I2C Master interface but when I
send the start bit I am seeing a series of what appears to be clocks on the
SCL line and nothing on the SDA.

 

I would expect SDA to be high at the same time as SCL goes hi and then SDA
goes low but all I see is a clock output on SCL.

 

 

I am using the library from this website.

Any ideas what I am missing?

 

Dave.
