Detailed Description
This class provides an accessor of fields contained in one or more consecutive UM7 registers. Each register is nominally a uint32_t, but XYZ vectors are sometimes stored as a pair of int16_t values in one register and one in the following register. Other values are stored as int32_t representation or float32s.
This class takes care of the necessary transformations to simplify the actual "business logic" of the driver.

| void * um7::Accessor_::raw | ( | ) | const |
This is ridiculous to have a whole source file for this tiny implementation, but it's necessary to resolve the otherwise circular dependency between the Registers and Accessor classes, when Registers contains Accessor instances and Accessor is a template class.

Member Data Documentation
| const uint8_t um7::Accessor_::index |
Number/address of the register in the array of uint32s which is shared with the UM7 firmware.
Definition at line 107 of file registers.h.
| const uint16_t um7::Accessor_::length |
Length of how many sub-register fields comprise this accessor. Not required to stay within the bounds of a single register.
