 Embassy provides both Hardware Abstraction Layers, and an executor/runtime, while RTIC aims to only provide an execution framework. For example, embassy provides `embassy-stm32` (a HAL), and `embassy-executor` (an executor). On the other hand, RTIC provides the framework in the form of [`rtic`], and the user is responsible for providing a PAC and HAL implementation (generally from the [`stm32-rs`] project).
 
-Additionally, RTIC aims to provide exclusive access to resources on as low a level of possible, ideally guarded by some form of hardware protection. This allows for access to hardware while not necessarily requiring locking mechanisms on the software level.
