IPC Pingpong!
|
|
=============
|
|
|
|
This example is to illustrate the usage of RIOTs IPC messaging system.
|
|
|
|
The application starts a second thread (in addition to the main thread) and sends messages between
|
|
these two threads. The main thread calls `thread_send_receive()` in an endless loop. The second
|
|
thread receives the message, prints `2nd: got msg from x` to stdout and sends a reply message with
|
|
an incrementing number back to the main thread. The main thread then prints the number it received
|
|
from the 2nd thread.
|
|
|
|
The correct output should look like this:
|
|
```
|
|
This is RIOT! (Version: xxx)
