Hi NevadaMark,
Now I realize I should have my own discrete design. Maybe ADXL products will be suitable for my project and analog output will be the best choice to support continuous data streaming.
It's the first time I hear the smart interface software suite. I will check it, thanks! Please forget about the transfer speed of Android device, I'm sure that It can't fix the problem as title. SPI interface separates writting/reading parts. There is no possible to design getting data continuously from ADIS16223(SPI).
This is the project from my school, I'm try to make an instrument that can measuring vibration.
Thank you so much! By the way, I think the best way to fix this problem is changing another sensor.
