Thanks
Yes,of course ,the problem, as I see it , is that the pbp cannot produce a repeated start .
I used a logic analizer -----> the accelerometer sends acknowlage signals.
the data sheet demands an Sr (repeat start) in order to read the device.
the device resets the address register to zero if the master sends a STOP.
I can read only the top seven registers only.(there are a lot of registers).
