[Tinyos-help] question on simple_transmit from Rfm_model.c
Hi,I have a question about the following code from Rfm_model.c. The parameter bit can be 1 or 0. When simple_trasmit is transmitting bit 1, transmitting[modeID] is set to 1, meaning it's transmitting. However, when simple_transmit is transmitting bit 0, transmitting[modeID] is set to 0, meaning it's not transmitting (actually it's transmitting bit 0). Why is it so? I must have the concept wrong. Could any help me on this?
void simple_transmit(int moteID, char bit) { int i; transmitting[moteID] = bit; for (i = 0; i < tos_state.num_nodes; i++) { radio_active[i] += bit; }}Regards,
Haibin

[Tinyos-help] Boomerang UART0 Sample
There is a link failure on the http://www.moteiv.com/community/Boomerang_UART0_Sample page. I can´t download the Moteiv Boomerang Uart0 Sample.tar.gz. I think I can use the UART as a simple debuger. Does anyone used the UART as a trace? /Jörgen Johansson ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

[Tinyos-help] Conversion of Telos B RSSI
To All:
Thanks to those who helped me get the RSSI sent over the serial port.
I am using the Telos B motes and doing some RSSI experiments. I am in
the process of modifying the serial forwarder some so that it will
convert the RSSI value I receive over the serial port to the actual
RSSI value. In the sflisten.c file, I have added the following code
to do this conversion before displaying it on the monitor:
const unsigned char *packet = read_sf_packet(fd, &len);
/*Perform 2's complement conversion and add offset (-45 dBm)*/
if (packet[10] < 128) //Positive Number
adj_rssi = packet[10];
if (packet[10] > 127) //Negative number
{
adj_rssi = -1*((packet[10] - 1)^(0xFF))-45;
}
if (!packet)
exit(0);
/*Display various information from the packet to monitor*/
printf("Node ID: ");
printf("%02x ", packet[12]);
printf("RAW RSSI: ");
printf("%02x ", packet[10]);
printf("Adjusted RSSI: ");
printf("%d ", adj_rssi);
putchar('\n');
fflush(stdout);
free((void *)packet);
The way I understand it, the raw RSSI is an 8-bit unsigned integer.
So, I have to do the two's complement conversion and add the offset.
Then I simply parse out what I want from the packet and print it
along with the converted RSSI to the screen. Does anyone see an
obvious flaw in my conversion or a more compact way to do the
conversion--aside from changing the if/if to and if/else. (I was
coding very late last night lol)
Many thanks again for the help.
Paul

Re: [Tinyos-help] Error during installing image on Telos
Unless you actually have one of the original Telos Rev A motes (there are not that many), you probably mean "make telosb" for Telos Rev B or "make tmote" for Tmote Sky, instead of "make telos". - Cory On 6/2/06, Tarun Banka <[EMAIL PROTECTED]> wrote: Dear All, I am facing problem while installing image on the mote.

Re: [Tinyos-help] Error during installing image on Telos
Tarun, I'm assuming that you are using either a Tmote Sky or a Telos rev. B. If you're using a Tmote Sky I would suggest you download the Boomerang distribution from Moteiv, and after you've installed it, use make tmote install,1 bsl,3 If you're using a Telos rev B. you should use make telosb install,1 bsl,3 Platform identifier telos refers to Telos rev. A, which uses a different MCU and a different sequence to enter the BSL programming mode.
