hi

Im using keil developing on a stm32f4 discovery board.

im trying to make a function pointer to be used by other modules.

something like:

extern void (*p)() ;

void myfunc()

{

    printf(''function pointer'');

}

somefunction(struct Adc *instance)

{

    p = myfunc();

}

i get the following error at the ''p = myfunc();''-line:

error:  &sharp513: a value of type ''void'' cannot be assigned to an entity of type ''void (*)(void)''

know  this  is prob a noob question  - but ive tried finding a solution - but cannot seem to solve it.

can any1 tell me waht im doing wrong?

thanks in advance

You're trying to assign the pointer, not call the function

p = myfunc;
