Решение задачи linuxnyasha с выщёлкиванием типов из списка типов по переданным индексам
#include <type_traits>
// ---------------- Исходные типы
// Структура используется только как хранилище типов
// Наверняка можно сделать так, чтобы её можно было сделать
// только внутри declspec, но зачем нам троллейбус из буханки,
// и так непросто вышло

Save some variables across all Arduino resets and most reprogrammings without EEPROM
struct SaveableData{
uint32_t update_counter;
};
struct UploadSafe{
char dummy[64];
uint32_t flag;
//Unless more than 64 bytes of global/static variables
//added/removed this will be saved

handy print for Arduino
//example:
//multiprint("I = ")(10)("A")()("U = ")(10)("V")();
//result:
//I = 10A
//U = 20V
//
//arguments -- same as Serial.print
//no argument -- Serial.println()
