FreeRTOS Stream and Message Buffer on Raspberry Pico: specialised to handle interrupt-to-task and multi-core messages/products/raspberry-pi/b/blog/posts/freertos-buffered-queue-on-raspberry-pico-specialised-to-handle-interrupt-and-multi-core-messagesThe Stream (and Message) Buffer is one of the more recent additions to FreeRTOS. A construct that&#39;s useful in specific (yet commons) situations: moving data from an interrupt (e.g.: UART TX interrupt) to an RTOS task for processing in a multi-core sen-USTelligent Community 12RE: FreeRTOS Stream and Message Buffer on Raspberry Pico: specialised to handle interrupt-to-task and multi-core messageshttps://community.element14.com/products/raspberry-pi/b/blog/posts/freertos-buffered-queue-on-raspberry-pico-specialised-to-handle-interrupt-and-multi-core-messagesSun, 22 Sep 2024 05:51:44 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:66807fd7-344d-4fb4-9097-053b93218420embeddedguy2<p>What about mutual exclusion? does this feature include some sort of semaphore or mutexe in-built?</p><img src="https://community.element14.com/aggbug?PostID=28355&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">RE: FreeRTOS Stream and Message Buffer on Raspberry Pico: specialised to handle interrupt-to-task and multi-core messageshttps://community.element14.com/products/raspberry-pi/b/blog/posts/freertos-buffered-queue-on-raspberry-pico-specialised-to-handle-interrupt-and-multi-core-messagesSat, 21 Sep 2024 19:23:48 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:66807fd7-344d-4fb4-9097-053b93218420Jan Cumps0<p>note to self: for next post, <a href="https://www.freertos.org/Community/Blogs/2020/simple-multicore-core-to-core-communication-using-freertos-message-buffers" rel="noopener noreferrer nofollow" target="_blank" data-e14adj="t">description from the FreeRTOS founder</a>.</p><img src="https://community.element14.com/aggbug?PostID=28355&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">RE: FreeRTOS Stream and Message Buffer on Raspberry Pico: specialised to handle interrupt-to-task and multi-core messageshttps://community.element14.com/products/raspberry-pi/b/blog/posts/freertos-buffered-queue-on-raspberry-pico-specialised-to-handle-interrupt-and-multi-core-messagesSat, 21 Sep 2024 18:19:15 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:66807fd7-344d-4fb4-9097-053b93218420DAB1<p>How much data are they allowing per event?</p><img src="https://community.element14.com/aggbug?PostID=28355&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">
