Hi As you know you can post tasks in order to run them "when it's possible".
I'd like to know if there's any way to send to sleep a task. Let's take a look at an example situation of what I'm talking about. Let's imagine a neighbor table, that you're going to update (maybe refresh timestamp, or clear old entries..). While checking the table you must keep the data consistent, so you have at least 2 ways: 1. Keep the updating code inside an atomic block. Doing this way you could even loose packets, because interrupts are disabled and the transceiver can't notify of an incoming packet. 2. Protect the same code for example with something similar to semaphores. The code for getting it is easy, and you can reduce the size of atomic blocks (you should only use them when updating the semaphore status). The problem for the second option is that only works if you can "send to sleep" the current task and give the control to another one (at least for a short period of time). Of course It's only possible if tinyOS is a multitask OS.. So.. can this (or something similar) be done in tinyOS? regards :D __________________________________________________ Correo Yahoo!
