Hello Brett,

I compiled Your posting on ARM-GCC and IAR_ARM_EWKickstart.
Now GCC produces many warnings, IAR- warnings an errors.
Anyway, i must learn more for pointers.
Thank You for help!
If not bored - one last question:
I suppose this code is compiled well on Your system.
What statement is ok to call function pointed by "myfunctionptr" ( commented below "POINTEDfunctionAA")?

regards
Stefan
