What is the difference between i2c and PS/2 ????? Can i use i2c ?

Fucking shit, the DATA line is valid when CLOCK RISES. Or am I wrong?

Now I successfully programmed my own PS/2 interface (visit my channel), and I used the rising edge of the clock.

looks like you have the HP 54112D digitizing scope. How did you get the OFFSET setting off the display? Mine has it ON by default and it's annoying. Could not find any settings on menu to remove it.
