I would like to know about asynchrounous reads with the ADXL345. Can the device be controlled as far as timing with an outside source and therefore obtaining an odd sample rate say 192 Hz?
The sampling rate is determined internally.
However, it seems to me that letting the device run at, say 800 hz and reading the x,y,z buffers at 192 hz would achieve what you want to do.
Unless I misunderstood your question.
