RE: [Tinyos-help] choosing mica2 operating RF frequency
Title: Message Ok, added inthe ability to connect toafew more CC1000 interfaces in the new radio stack: * RadioSendCoordinator * RadioReceiveCoordinator * CsmaControl * CsmaBackoff * RadioTimeStamping Again, anyone can get this new stack in the TinyOS 1.x CVS under /contrib/rincon/tos/lib/CC1000Radio. Just edit your Makefiles to point to the CC1000Radio directory and sub-directories to override the default 1.xCC1000 stack found in /platform/mica2 If you're doing time synchronization, you should take a look at TinyOS 2.x's RadioTimeStamping interface, also available in the "interfaces" directory of CC1000Radio. -David -Original Message-From: Conor Todd [mailto:[EMAIL PROTECTED] Sent: Monday, August 28, 2006 3:08 PMTo: David MossCc: tinyos-help@millennium.berkeley.eduSubject: Re: [Tinyos-help] choosing mica2 operating RF frequencyHoly moly, that's quite different than the CC1000 architecture for the Mica2 in TinyOS-1.1.15!I'm using the RadioReceiveCoordinator interface for the CC1000 in my app; can you give me any direction as to how I might switch from the standard CC1000 stack to the Rincon code? - Conor On 8/28/06, David Moss [EMAIL PROTECTED] wrote: If you're using the default CC1000 stack, connect your app to the CC1000Control interface provided by CC1000ControlM and call CC1000Control.TuneManual(86800).

RE: [Tinyos-help] choosing mica2 operating RF frequency
Title: Message Conor - Ya, that was one interface that I didn't explicitly implement in thisstack.The majority of the codecame from TinyOS 2.x, backported to 1.x with improvements. Since we need this stack to be compatible with existing 1.x apps, I'll add it in and shoot you an update, probably sometime this week.
