5.2.2
The archived library files contain all the individual object files for each library function.
When linking an application, the library file must be provided as an input to the linker
(using the
application may be linked into the application.
A typical C application will require three library files:
libpic30-
more on OMF-specific libraries.) These libraries will be included automatically if linking
is performed using the compiler.
5.2.3
Signed fixed point types are defined as follows:
Qn_m
where:
• n is the number of data bits to the left of the radix point
• m is the number of data bits to the right of the radix point
For convenience, short names are also defined:
Functions in the library are prefixed with the type of the return value. For example,
_Q15acos returns a Q15 value equal to the arc cosine of its argument.
Argument types do not always match the return type. Refer to the function prototype
for a specification of its arguments.
In cases where the return value is not a fixed point type, the argument type is appended
to the function name. For example, function _itoaQ15 accepts a type Q15 argument.
In cases where two versions of a function are provided, with the same return type but
different argument types, the argument type is appended to the function name. For
example:
_Q0_15
_Q15_16
_Q1_30
_Q16reciprocalQ15
_Q16reciprocalQ16
