I2C Read/Write problems

[JD123]

Wow... lots of help... I'm attempting to get the read to work, using $20 for the control byte. I'll see what I can do...

Here's the $24 million dollar question:

Does the documents for the slave IC say send address $10 or does it say that its address is $10.

So far as the clocking speed, there can be pulses that come close to 400k being send out, but that's just for a short period of time. The clocking speed will most likely vary in speed depending on what's being done. BTW, how are you reading the clocking speed? O-scope or frequency counter?
