[Tinyos-help] Limited number of timers?

2008-07-28 Thread Nicola Wegner
Hi everybody, just a short question to the micaz platform. Is the number of timers I can use limited? I read in TEP102 that there are only three compare registers for each of the 16-bit timers. Does this mean that I can use only 6 timers at a time? Or does TinyOS provide some kind of

Re: [Tinyos-help] Surprising Timer Readings

The timer is all right. I realized what was the problem. Serial port communication played a trick on me. The program which I used to read the port gave out data bytes 0x7E and 0x7D as 0x7D 0x5E and 0x7D 0x5D. This is because byte 0x7E is reserved as a frame delimiter, and 0x7D is reserved as

[Tinyos-help] what affects RSSI

2008-07-28 Thread Min Guo
Surely the longer the distance, the weaker the RSSI. Besides, if several senders are sending, due to the overlapping and the phase differences of signals, isn't it possible that the receiver may sometimes detect a stronger and sometimes a weaker RSSI than only one sender is sending? I made an

For TinyOS 2.x see VirtualizeTimerC. I believe `new TimerMilliC()`, has the same affect, but allows a different way to wire. There is a different between hardware-level HPL/HAL timers and the exposed software timers in the HIL. HTH, Paul On Mon, Jul 28, 2008 at 1:38 AM, Nicola Wegner [EMAIL

That is byte stuffing and is part of the serial protocol stack (HDLC? if memory serves me right). What I don't understand is why you even saw them. Are you looking at the raw stream? I would have thought they would have been transparent to you because you'd be looking at the ends of the

Just some things to try... I'd bet that the message buffer gets reused or erased before your second send can complete. You may also have trouble calling the send directly from the done, since done is in an event context which is sometimes tantamount to an interrupt, perhaps try copying the
