FRC 2022 Analog Device IMU 16448 and 17470 support

[JimASim]

Analog Devices posted that the 16448 was being phased out a year or two ago.  I noticed that neither the 16448 and 16470 are listed in the third party devices in the documentation web page.  I also noticed that both drivers were imported into the WPILIB for Java/C++.  Is this going to be done with for LabVIEW, or should the drivers from previous years work okay, or is support for these being phased out.  The install packages for previous years still appear to exist.

Thanks

The drivers for previous year should work. I did find issues with how one of them was being calibrated, so I'll have to see if those changes made it in.

At the moment, neither of these devices will work for any language. An underlying FPGA bug needs to be fixed so that the data streaming from SPI will operate correctly.

That is good to know as we have relied on the 16448. 

We also found a calibration issue with the 16448 in the past.  After fixing this, the calibration was pretty solid, after the device was warmed up.

Thanks

I put a work around to the Auto SPI issue here.
