How I can send a message to a task?

Posted by pav on April 25, 2010
Hi, is it possible to send the message to the task(s)? I mean I would like to send message from a task1 to task2. But only to the task2.
How I can do that?
Can anyone help me, please?

Read the web site http://www.freertos.org/Inter-Task-Communication.html and look at the demo aps. There are a lot of examples.

Thank you edwardds3, but this is not what I meant.
I know how I can using a queue or sharing resources but I would like to send a message to only one task.
Examples: I have task1, task2 and task3. And now I would like to send message from task1 to task2(and task3 dont't know anything that message). So same way as using a mailbox. I think that only possibility is use own queue between every tasks=> Queue1 for task1 and task2, Queue2 for task1 and task3 and Queue3 for task2 and task3.
Is this only way to do it?

Using a queue for each message path certainly seems like a reasonable approach. Isn't that how a mailbox would be implemented?
