For RTIC 1.0 and 2.0 we instead assume the user has a time library, e.g. [`fugit`], as the basis for all time-based operations when implementing `Monotonic`. These libraries make it much easier to correctly implement the `Monotonic` trait, allowing the use of almost any timer in the system for scheduling.
The trait documents the requirements for each method. There are reference implementations available in [`rtic-monotonics`](https://github.com/rtic-rs/rtic/tree/master/rtic-monotonics/src) that can be used for inspriation.

- [`Systick based`], runs at a fixed interrupt (tick) rate - with some overhead but simple and provides support for large time spans
- [`RP2040 Timer`], a "proper" implementation with support for waiting for long periods without interrupts. Clearly demonstrates how to use the `TimerQueue` to handle scheduling.

* Implement the trait behind a feature flag in [`rtic-monotonics`], and create a PR for them to be included in the main RTIC repository. This way, the implementations of are in-tree, and RTIC can guarantee their correctness, and can update them in the case of a new release.
* Implement the changes in an external repository.
<!-- TODO: remove 1.0.x examples? -->
# V1.0.x
Here is a list of `Monotonic` implementations for RTIC 1.0:
- [`STM32F411 series`], implemented for the 32-bit timers
- [`Nordic nRF52 series Timer`], implemented for the 32-bit timers
- [`Nordic nRF52 series RTC`], implemented for the RTCs
- [`DWT and Systick based`], a more efficient (tickless) implementation - requires both `SysTick` and `DWT`, supports both high resolution and large time spans
If you know of more implementations feel free to add them to this list.
