Detailed Description

Concrete implementation of the platform specific classes/features of the Cpl::System namespace interfaces for a Baremetal/Singled-threaded system.

Platform Dependent Behaviors:

Thread - The threading class is stubbed out so that any call to the interface are benign. The Thread interface will "report" a single thread. The application cannot create threads.

Mutex - The mutex interface is effectively all NOPs

GlobalLock - The GlobalLock can be mapped to a platform's EI/DI calls, or to NOPs (on the Windoze, this mapped to NOPs)

Semaphore - Fully functional. However since there is only 'one thread' - if a semaphore's count is at zero and the wait() method is called the "main thread" will block/busy-wait forever unless the semaphore's su_signal() method is called from an ISR context.

Tls - Fully functional.

ElapsedTime - The platform is required to provide the number of milliseconds since power-up.

EventLoop - Fully functional. This includes EventFlags and Software Timers.

Classes
class	Thread
	This concrete class implements 'enough' of a Thread object to support Cpl::System framework on a bare metal system (a system that has only ONE thread and potentially ISR contexts). More...

Functions
void	initialize (void) noexcept
	This method is used to initialize the HAL/Target layer.
void	busyWait (unsigned long waitTimeMs) noexcept
	This method performs a busy-wait for the specified number of milliseconds.
unsigned long	getElapsedTime (void) noexcept
	This method returns the current elapsed time since power-up in milliseconds.

Function Documentation

busyWait()

void Cpl::System::BareMetal::busyWait ( unsigned long  waitTimeMs )

noexcept

This method performs a busy-wait for the specified number of milliseconds.

getElapsedTime()

unsigned long Cpl::System::BareMetal::getElapsedTime ( void  )

noexcept

This method returns the current elapsed time since power-up in milliseconds.

initialize()

void Cpl::System::BareMetal::initialize ( void  )

noexcept

This method is used to initialize the HAL/Target layer.

What needs to be an/or is initialized is platform specific.
