please use pgm_read_ptr instead of pgm_read_word for getting pointers to make the lib portable to 32bits targets

[gzied]

using pgm_read_word for getting pointers will trim the pointers on 32bits targets. please use pgm_read_ptr instead.

fixed Menu.cpp shall be
const char * Engine::getLabel(const Item_t * item) const {
return (const char *)pgm_read_ptr((item == NULL) ? &currentItem->Label : &item->Label);
}

const Item_t * Engine::getPrev(const Item_t * item) const {
return (const Item_t *)pgm_read_ptr((item == NULL) ? &currentItem->Previous : &item->Previous);
}

const Item_t * Engine::getNext(const Item_t * item) const {
return (const Item_t *)pgm_read_ptr((item == NULL) ? &currentItem->Next : &item->Next);
}

const Item_t * Engine::getParent(const Item_t * item) const {
return (const Item_t *)pgm_read_ptr((item == NULL) ? &currentItem->Parent : &item->Parent);
}

const Item_t * Engine::getChild(const Item_t * item) const {
return (const Item_t *)pgm_read_ptr((item == NULL) ? &currentItem->Child : &item->Child);
}
