42 \defgroup compat_ina90 <compat/ina90.h>: Compatibility with IAR EWB 3.x
43
44 \code #include <compat/ina90.h> \endcode
45
46 This is an attempt to provide some compatibility with
47 header files that come with IAR C, to make porting applications
48 between different compilers easier. No 100% compatibility though.

50 \note For actual documentation, please see the IAR manual.
