| IPC Service |
| ########### |
| |
| Overview |
| ******** |
| |
| IPC Service is an abstraction layer. |
| It needs the corresponding backend registered for proper operation. |
| You can use any IPC mechanism as a backend. |
| In this sample, it is a multiple instance of RPMsg. |
| This sample demonstrates how to integrate IPC Service with Zephyr. |
