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?

Mr.E., cute program you got there.

See in the program where you enter "1010000" for the address? That's $50 for the address.

Any who, I think everyone's got the idea, in agreement or not. I just took the O/P literally for the words he used and opened a can of do-do. Sorry.

OK i see what you mean... $A0 is the ControlByte (Controlword or slave address depending of the document you have on hand... says datasheet) but yeah $50 for the address... this said, i don't remember to have any issue with any datasheet using what they said, whatever how they call it maybe why i didn't understood your point

We still don't see the O/P datasheet or part#... weird eh?

Dispersion123, how's it coming, reading the 2 bytes?
