Hi Alain,

short int on arm-gcc isn´t a char thats right. sizeof tells me same length
of integer and short int both 2 bytes. So my mistake was a wrong type cast.
(short int to char thats not realy good) 
But i´ve seen that the "%hhx" modifier often is used for returning a char. 
If you use hh gcc warning shows that a char is expected. 
So i changed getf  to use hh and then all is ok. 

I think if the comiler expects such thing than scanf should do it, or am i
wrong ?
