>readeeprom(rxbuffer[2],8,(char)&rxbuffer[0]);   <---- this is wrong, you
don't want to cast
                                                       the pointer to char!

readeeprom(rxbuffer[2],8,(char *) &rxbuffer[0]); <---- this is correct, but
I don't know why
                                                       you would want to
write it this way!

readeeprom(rxbuffer[2],8,rxbuffer);              <---- this is how I would
write it


IOW:-
char rxbuffer[10];  NOT char * rxbuffer[10];  (the latter would be an array
of pointers to char)
readeeprom(rxbuffer[2],8,rxbuffer);

It sounds like the pointer-array duality in C has you snagged, if  you
persist, all will
become clear.

Best regadrs,
