Fix casting warnings that prevent using -Werror
The variables used to hold pointers are only 8 bit wide. even if
pointers on AVR are 16 bit wide.
The high byte can be discarded if empty, but this must be somehow
notified to the compiler, otherwise it will emit a warning that
prevents from using ssystem-wide -Werror build flag.
