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!!
