Multithreading example/lib code 

Hi there,

you can grab the multithreading sources here

Little list of features / functions:

• Critical Sections, which will not be interrupted by a thread shedule:
  • EnterCriticalSection()
  • LeaveCriticalSection()
• Statistical functions:
  • GetThreadCount(GTC_ALL | GTC_RUNNING | GTC_AVAILABLE)
• ThreadControl (self targeted):
  • ThreadWait() - suspends thread till IRQ occurred
  • EndCurrentThread(value) - ends thread and sets a return value
• ThreadControl (other threads):
• CreateThread(entry,stack) - creates & starts a new thread (returns threadID)
• KillThread(threadID) - kills a thread
• GetThreadStatus(threadID)
• SetThreadStatus(threadID)
• GetThreadReturnValue(threadID)
• Semaphores
• Semaphores are using suspend-resume-queuing :
• CreateSemaphore()
• AquireSemaphore(semaphore)
• ReleaseSemaphore(semaphore)
• IRQ:

Since the IRQ handler is captured, you can set a custom IRQ Handler now by

• SetIRQHandler(handler)

• All threads of status THREAD_STATUS_RUNNING are sheduled cyclic on 33kHz
  or any occured IRQ (Timer3 is reserved)
