Collaboration diagram for Concurrency:

Classes
class	BufferRP2040T< T >
	Buffer implementation which is based on a RP2040 queue. This class is intended to be used to exchange data between the 2 different cores. Multi-core and IRQ safe queue implementation! More...
class	NoInterruptHandler
	Disable, enable interrupts (only on the actual core) More...
class	MutexRP2040
	Mutex API for non IRQ mutual exclusion between cores. Mutexes are application level locks usually used protecting data structures that might be used by multiple threads of execution. Unlike critical sections, the mutex protected code is not necessarily required/expected to complete quickly, as no other sytem wide locks are held on account of an acquired mutex. More...
class	BufferRTOS< T, TAllocator >
	Buffer implementation which is using a FreeRTOS StreamBuffer. The default allocator uses psram is available. More...
class	MutexRTOS
	Mutex implemntation using FreeRTOS. More...
class	MutexRecursiveRTOS
	Recursive Mutex implemntation using FreeRTOS. More...
class	QueueRTOS< T, TAllocator >
	FIFO Queue whch is based on the FreeRTOS queue API. The default allocator will allocate the memory from psram if available. More...
class	Task
	FreeRTOS task. More...
class	SynchronizedQueue< T, TMutex, TAllocator >
	FIFO Queue which is based on a List that is thread save. More...
class	LockGuard
	RAII implementaion using a Mutex: Only a few microcontrollers provide lock guards, so I decided to roll my own solution where we can just use a dummy Mutex implementation that does nothing for the cases where this is not needed. More...
class	MutexBase
	Empty Mutex implementation which does nothing. More...
class	SynchronizedBuffer< T >
	Wrapper class that can turn any Buffer into a thread save implementation. More...
class	SynchronizedStream
	Wrapper class that can turn any Stream into a thread save implementation. This is done by adding a Mutex to the Stream. The read and write operations are buffered and the access to the stream is protected by the Mutex. More...
