WebOct 20, 2024 · The reason for calling vTaskDelay () is to give other tasks a chance to run while this task is delaying. So it seems counterproductive to disable interrupts with taskENTER_CRITICAL. If you don't want other tasks to run during the delays then call a non-blocking delay function rather than vTaskDelay ().

Note. The critical section API can be called recursively (i.e., nested critical sections). Entering a critical section multiple times recursively is valid so long as the critical section is exited the same number of times it was entered.

WebJun 13, 2024 · Calls to taskENTER_CRITICAL () and taskEXIT_CRITICAL () are designed to nest. Therefore, a critical section will only be exited when one call to taskEXIT_CRITICAL () has been executed for every preceding call to taskENTER_CRITICAL (). That sounds like the opposite of nesting to me...but I just work here. IMO It is nesting (or re-entrant).

WebApr 13, 2024 · This is exactly what critical sections were designed for. We also discussed a few times that there are more fine granularity mechanisms to accomplish mutual exclusion - for example, if the exclusion is only against one single thread of execution, then a mutex (if the other thread is a task) or a “surgical” diasable of a particular interrupt (if the other …

WebThe taskENTER_CRITICAL () and taskEXIT_CRITICAL () macros provide a basic critical section implementation that works by simply disabling interrupts, either globally, or up to a specific interrupt priority level. See the vTaskSuspendAll () RTOS API function for information on creating a critical section without disabling interrupts. Videos, podcasts, blogs, and other content resources shared by members of the F… WebCalls to taskENTER_CRITICAL or taskEXIT_CRITICAL each provide a spinlock object as an argument. The spinlock is associated with a shared resource requiring access protection. When entering a critical section in ESP-IDF FreeRTOS, the calling core will disable interrupts similar to the vanilla FreeRTOS implementation, and will then take the spinlock and enter …

WebDec 7, 2024 · STM32 I2C peripheral is simple enough to use without the burden of HAL libraries, additionally I needed a custom driver because my application uses FreeRTOS.
