| # RTOS Abstraction Library | |
| The RTOS Abstraction APIs allow middleware to be written to be RTOS aware, but not need to care about what the actual RTOS is. | |
| ### What's Included? | |
| The this release of the RTOS Abstraction API includes support for the following: | |
| * APIs for interacting with common RTOS Features including: | |
| * Threads | |
| * Mutexes | |
| * Semaphores | |
| * Timers | |
| * Queues | |
| * Events | |
| * Implementations are provided for | |
| * FreeRTOS | |
| * RTX (CMSIS RTOS) | |
| * ThreadX | |
| * WICED RTOS | |
| ### What Changed? | |
| #### v1.6.0 | |
| * Added WICED RTOS support | |
| #### v1.5.0 | |
| * Added additional parameter validation for ThreadX | |
| * Removed the explicit in_isr argument from all functions. CPU status registers are used to automatically determine whether a function is executing in an interrupt context. | |
| * Renamed all functions in order to make grouping more clear. The original function names are deprecated. | |
| * to make grouping more clear. The original function names are now considered deprecated. | |
| #### v1.4.0 | |
| * Added new thread functions: cy_rtos_wait_thread_notification and cy_rtos_set_thread_notification | |
| * Minor documentation updates for clarity | |
| #### v1.3.1 | |
| * Fixed a couple bugs in the FreeRTOS port | |
| #### v1.3.0 | |
| * Update to work with a wider range of MCUs | |
| * Fixed a race condition in the worker thread | |
| * Fixed possible issue with thread priorities | |
| * Minor documentation updates | |
| #### v1.2.2 | |
| * Minor update for documentation & branding | |
| #### v1.2.1 | |
| * Fixed possible race condition in cy_rtos_join_thread for FreeRTOS | |
| * Minor documentation updates | |
| #### v1.2.0 | |
| * Added utility library for for creating background worker threads: cy_worker_thread.h | |
| * Added support for getting a semaphore's count: cy_rtos_get_count_semaphore() | |
| * Added support for non-recursive mutexes: cy_rtos_init_mutex2() | |
| * Added default implementations for FreeRTOS vApplicationGetIdleTaskMemory, vApplicationGetTimerTaskMemory, and vApplicationSleep | |
| * Added support for ThreadX | |
| NOTE: The vApplicationSleep implementation for FreeRTOS depends on the psoc6hal 1.2.0 or later. | |
| #### v1.1.0 | |
| * Fixed an issue with the FreeRTOS implementation where it would always allocate memory for the thread stack, even if a pre-allocated buffer was provided. | |
| * Removed usage of assert() and replaced with CY_ASSERT() | |
| #### v1.0.1 | |
| * Added a new function to get the ID of the currently running thread. | |
