This is mainly used to facilitate debugging. PcName – A descriptive name for the task. continuous loop), or should be terminated using vTaskDelete function. Tasks must be implemented to never return (i.e. PvTaskCode – Pointer to the task entry function. This function is similar to xTaskCreate, but allows setting task affinity in SMP system.

IPC tasks are used to implement the IPC feature. IPC tasks created for (and pinned to ) each CPU. Idle tasks created for (and pinned to) each CPU This task will self delete when app_main returns These tasks are: List of Tasks Created During Startup  The main task is one of multiple tasks that are automatically spawned by ESP-IDF during startup. The app_main function is called from the main task. The app_main function is allowed to return at any point (i.e., before the application terminates). Typically, users would spawn the rest of their applications task from app_main. The entry point is a user defined void app_main(void) function. Instead, ESP-IDF FreeRTOS is started automatically. Unlike Vanilla FreeRTOS, users must not call vTaskStartScheduler().

In the case that a task function mistakenly returns (i.e. Alternatively, users can also search for occurrences of CONFIG_FREERTOS_UNICORE in the ESP-IDF components.ĬONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION will trigger a halt in functions in ESP-IDF FreeRTOS that have not been fully tested in an SMP context.ĬONFIG_FREERTOS_TASK_FUNCTION_WRAPPER will enclose all task functions within a wrapper function. For more details regarding the effects of running ESP-IDF FreeRTOS on a single core, refer to ESP-IDF FreeRTOS Single Core. Futhermore, this option may affect behavior of components other than freertos. Note that this is not equivalent to running Vanilla FreeRTOS.

For a full list of ESP-IDF FreeRTOS configurations, see Project ConfigurationĬONFIG_FREERTOS_UNICORE will run ESP-IDF FreeRTOS only on CPU0. The following section highlights some of the ESP-IDF FreeRTOS configuration options. Any FreeRTOS configuration that is exposed to the user will be done so via menuconfig.ĮSP-IDF FreeRTOS can be configured in the project configuration menu ( idf.py menuconfig) under Component Config/FreeRTOS. However, in ESP-IDF FreeRTOS, the ``FreeRTOSConfig.h`` file is considered a private and must not be modified by users.

Through these macros, the kernel’s scheduling behavior and various kernel features can be enabled or disabled.

Vanilla FreeRTOS allows ports and applications to configure the kernel by adding various #define config. ESP-IDF FreeRTOS is based on Vanilla FreeRTOS v10.4.3įor more information about the SMP changes of ESP-IDF FreeRTOS, see ESP-IDF FreeRTOS (SMP)įor more information about the features added to ESP-IDF FreeRTOS, see FreeRTOS Supplemental Features.
