Hi guys,

I have been using 7 nodes with mega1281s and CC2420s for RF data logger for quite some time, I use one node connected to PC to collect all the incoming RF packets, and the parallel timing scheduling is really killing me. So I'm asking if anyone use some simulation tools for such purpose?

Got a block diagram of the system to show us?

no block diagram yet, but it's a star topology network where 6 nodes are leafs and 1 is coordinator which is connected to PC and send out beacon every second to sync other nodes. I can do the timing check in the old way by connecting some I/O pins of 7 nodes to a oscilloscope, but that will be a mess. I want the simulation on PC instead.

Supposedly, the author of simulavrxx has been using the tool to simulate a
multiprocessor AVR setup that controls his railway models.

Please don't send me PMs, use email if you want to approach me personally.

Yes it comes as part of the WinAVR package but if you mean a GUI front end then no.

If you have WinAVR installed drop to a DOS prompt and CD to \winavr\bin where you can then use "simulavr -d name_of_project.elf

But maybe start with \Winavr\doc\simulavr-0.1.2.1 though I realise it's a bit old school to actually start by reading a manual!
