Handling a Family of Hardware Devices with a Single Implementation
summary
Claims a single template implementation handles six Arduino Mega timers — two 8-bit and four 16-bit — by extracting differences into timer_traits with type aliases for clock select and count_t, using volatile register members and enum types for safety. Tools include templates, traits, enumeration types, operator overloading patterns and a class-specific operator new that maps the object to the hardware address. The result is one maintainable class template that compiles separately for each timer, preserves type safety, and keeps performance on par with handwritten register access.
