readMode

lowerWindow

protected static final I2cDeviceSynch.ReadWindow lowerWindow

One of two primary register windows we use for reading from the BNO055. Given the maximum allowable size of a register window, the set of registers on a BNO055 can be usefully divided into two windows, which we here call lowerWindow and upperWindow. When we find the need to change register windows depending on what data is being requested from the sensor, we try to use these two windows so as to reduce the number of register window switching that might be required as other data is read in the future.

upperWindow

protected static final I2cDeviceSynch.ReadWindow upperWindow

A second of two primary register windows we use for reading from the BNO055. We'd like to include the temperature register, too, but that would make a 27-byte window, and those don't (currently) work in the CDIM.
