Re: [avr-gcc-list] Table of function pointers

[Guy Robinson]

Hi Jon,
When I tried this the array was in SRAM. I don't think Avr-gcc understands
the const type as standard. I'm new to C but I think you have to use the
progmem
macros(progmem.h). I want the array of pointers to functions in the program
memory it's just how to get it there.

Still trying,

Guy

You have some stuff I'm not familar with.

Here is how I do arrays of pointers to functions:

/* prototypes for the actual functions */
void Cmd1(TByte bCmd);
void Cmd2(TByte bCmd);
void Cmd3(TByte bCmd);

/* the actual functions all must match the type TFunctionPtr */
typedef void (*TFunctionPtr)(TByte bCmd);

/* the array */
const TFunctionPtr CommandArray[] =
{
  Cmd1,
  Cmd2,
  Cmd3
};

/* how to call a function */
main()
{
  CommandArray[bIndex](bParameter);
}
