Within the same lock/unlock cage of semaphore, this IPC can be implemented to transfer data between the processes.

But I had difficulty understanding what CM4 was. I wondered if it was a Pi 4 Compute Module.&nbsp;</p> <p>I now know you mean Cortex-M4 but the acronym will get confusing if shortened to CM4, I&#39;ve not seen it shortened to that before.</p><img src="https://community.element14.com/aggbug?PostID=25724&AppID=392&AppType=Weblog&ContentType=0" width="1" height="1">
