how many Number of threads can be Created in STM32F207. I have created 6 threads successfully but when i am trying to created 7th thread its not working. On which factor thread number is defined how to increase it?
From the API documentation for the xTaskCreate() return value:
"If the task was created successfully then pdPASS is returned. Otherwise
errCOULDNOTALLOCATEREQUIREDMEMORY is returned."
So the task was not created because you ran out of heap memory?
Then read http://www.freertos.org/a00111.html which says how to allocate
more memory to FreeRTOS - see the configTOTALHEAPSIZE parameter.
Googling configTOTALHEAPSIZE then also provides a little more
information and links:
Hope that helps!
