ADIS16223 stability of received data

Hello, everyone.

I have recently been working with the ADIS16223 accelerometer.

SPI interface is working well, but the received data of buffer X, Y, Z are really unstable. What can I do?

I have tried to add low-pass filter which in datasheet Table 38.

Settings of AVG_CNT were 0xB800~0xB80A, but I couldn’t tell the differences between adding and non-adding.

Here is my test:

Put the accelerometer on the table.

MOSI: 0x1800 ( CAPT_BUFFZ ), 0x0000 ( Dummy )

The received data were unexpected!!

MOSI: 0x1800
MISO: Unstable value

  • Hey Mark,

    I noticed that there some imporvements and that it is quite hard to keep a documentation small but informative. Basically these sheets are supposed to provide informations to experienced people or professionals so in conclusion I have to say that your datasheets provide all the data which is necesarry. I´m working at college and we ordered a bunch of adis16223 for some r&d purposes. Nobody of us is a professional programmer and in fact we could not process every given information from this sheet or so to say it took some time to figure out what is important and what is not to realize a functional code example to measure acceleration data. I think this is not the common case so I´m fine with that but if you are realy interested in some suggestions there are only three little things I would recommend. At the end everything work fine and we are very satisfied with this advice. I learned with datasheets and examples from different devices to get things work with the adis16223. I recommended my colleagues to order a development kit next time to get in touch with new sensors from analog device I think this could have made things easier.

    best regards
