Expand description
A zero-copy queue for sending values between asynchronous tasks.
It can be used concurrently by a producer (sender) and a consumer (receiver), i.e. it is an “SPSC channel”.
This queue takes a Mutex type so that various targets can be attained. For example, a ThreadModeMutex can be used for single-core Cortex-M targets where messages are only passed between tasks running in thread mode. Similarly, a CriticalSectionMutex can also be used for single-core targets where messages are to be passed from exception mode e.g. out of an interrupt handler.
This module provides a bounded channel that has a limit on the number of messages that it can store. If this limit is reached, trying to send another message either waits or returns an error depending on the function.
