Typedefs

typedef int32 isf_microTeslas_fixed_32s1i14_t
 ISF sensors standard fixed point magnetometer type in microTeslas using AC_Fixed(32,14,1) notation This means of 32 total bits, 14 are used to represent the integer portion with the MSB as a sign bit. This leaves 17 bits for the fractional component. The LSB is therefore ~ 7.62939453125e-6 uT. The type can contain field strengths in the +/-8192 uT range. More...
