Betreff: [avr-gcc-list] Array of pointers to functions 

Hi, all,

I'm trying to call a function from an array, like this..

char f_cnt;

void fun1(void)
    {
        //some code
    }
//---------------------
void fun2(void)
    {
        //some code
    }
//---------------------
void fun3(void)
    {
        //some code
    }
//---------------------

void (*call_fun[])() PROGMEM = { fun1, fun2, fun3};  //This puts the addresses 
in code memory(seems
so from the .lst file).
//----------------------
void main(void)
    {
        (*call_fun[f_cnt])();  //But here I get a 'ld' instruction. How to 
cause an LPM instruction
to get the function address before the 'icall' ?
    }
//---------------------

Hello Royce 
Try this:


void (*func)();
func=(__LPM_word_classic__((PGM_P)call_fun[0]));
(func());

I looked in the produces .s file,seems to be ok.

Martin
