[Tinyos-help] radio hangup due to lost RXFIFO.readDone() event
Hi all, I'm working on the telosb mote using T2.1.0 and I accidentally found that sometimes the RXFIFO.readDone() event would not be triggered after calling call RXFIFO.continueRead or RXFIFO.beginRead. (in CC2420ReceiveP.nc) Once FIFOP goes low, and the radio state is not S_STARTED, the lost RXFIFO.readDone() cause the radio hangup, as FIFOP.fired event cannot be triggered again without reading at least one byte out from the RXFIFO. Did anyone happen to see this problem? Is it because of wrong CSN.set() calling or loss of SPI resource?

[Tinyos-help] a small bug in TOSSIM Live
Hi all,
I found a small bug in /tossim/sf/sim/SerialActiveMessageC.nc. If you have
already found it, please just ignore this mail.
In function sim_event_t* allocate_serial_deliver_event(int node, message_t*
msg, sim_time_t t),
the code is like evt-data = msg;, this pointer copy may not work
correctly.
When sending messages from JAVA to TOSSIM, the messages are always
corrupted.
Here is a quick fix, maybe you have a better one :)
sim_event_t* allocate_serial_deliver_event(int node, message_t* msg,
sim_time_t t) {
sim_event_t* evt = (sim_event_t*)malloc(sizeof(sim_event_t));
// Yang-
message_t* newmsg = (message_t*)malloc(sizeof(message_t));
memcpy(newmsg, msg, sizeof(message_t));
// -Yang
evt-mote = node;
evt-time = t;
evt-handle = serial_active_message_deliver_handle;
evt-cleanup = sim_queue_cleanup_event;
evt-cancelled = 0;
evt-force = 0;
// Yang-
//evt-data = msg;
evt-data = newmsg;
// -Yang
return evt;
}
event void Model.receive(message_t* msg) {
uint8_t len;
void* payload;
memcpy(bufferPointer, msg, sizeof(message_t));
// Yang-
if (msg!=0) free(msg);
//-Yang
payload = call Packet.getPayload(bufferPointer, call
Packet.maxPayloadLength());
len = call Packet.payloadLength(bufferPointer);
dbg(Serial, Received serial message (%p) of type %hhu and length
%hhu @ %s.\n,
bufferPointer, call AMPacket.type(bufferPointer), len,
sim_time_string());
bufferPointer = signal Receive.receive[call
AMPacket.type(bufferPointer)]
(bufferPointer, payload, len);
}

[Tinyos-help] low power listening in tossim under TinyOS-2.1
Hi all, Is it possible to simulate low power listening in tossim under T2? It seems like lpl implementation in T2 only works for testbed, please correct me if I'm wrong :) Or does someone has a beta version of low power listening component for T2's tossim? I would be very happy to help you verify it. Thanks for your help! -- Best, Yang ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] TOSSIM CC2420 simulation, CCA is always busy busy busy....
Hi Phil, I am using TOSSIM to do my simulation, but I met a problem here, the module I used is TOSSIM-CC2420 under /tinyos-1.x/beta/TOSSIM-CC2420 I use a root to do broadcasting periodly, the interval is 1 second, and other nodes do retransmission. I tract down my program and find that after several rounds of transmission, TOSH_READ_RADIO_CCA_PIN() is always FALSE in the root node then no other transmission can be done any more... It stuck there. I set the node number from 3 to 15, and this problem happens randomly I also tested my program in real sensor nodes, 16 Tmote Sky nodes, there is no such kind of problem. Root can continue running for thousands times of transmission. So I am wondering whether there is any potential bug in TOSSIM-CC2420?

[Tinyos-help] CC2420 lossy module in TOSSIM
Hi all, I am trying to use TOSSIM to do simulation for telosb in tinyos1.x, but I can not use lossy module to do build multihop topology... Does anyone use run -rf=yourlossyfile.nss nodeNUM ? It seems like my lossy.nss file does not work, seems like it is not read(I use lossyBuilder to generate this file) Can anyone give me some suggestions?

[Tinyos-help] questions about imote2 using tiyos1.x
Hi all, I am working on imote2 development with tinyos1.x now, I am a little confused about the register definition for PXA27X. from /opt/tinyos-1.x/beta/platform/pxa27x I got file pxa27x_registers_def.h (filetos1) from /opt/tinyos-2.x/tos/chips/pxa27x I got file pxa27x_registers.h(filetos2) The first file has few comments about the meaning of different registers, so I make a compare with the second file. However, I find some conflicts. (I just took a look at UART related register) filetos1 #define LCR_WLS(n) (n 0x3) filetos2 #define LCR_WLS(_x) ((_x) 0) /* Word Length Select */ filetos1 #define IIR_IID_MASK (~(((12)-1) 1)) filetos2 #define IIR_IID_MASK (0x3 1) /* Interrupt Source Encoded */ filetos1 #define IER_RTOIE (1 4) filetos2 #define IER_RTIOE (1 4) /* Receiver Time Out Interrupt Enable */ Will these differences cause potential bug? Which one is right? Does anyone have a developer guide for PXA27X? It seems like Intel removed related documents from the website... I got one namedPXA27x family design guide, but helps little, but I still do not know how to opeate pxa27x register... Very appreciated for your help!

[Tinyos-help] Tmote Sky DAC driver development
Hi all, I have a question about the DAC driver for Tmote sky node. Can anybody tell me some information about following definition? I cannot find useful info in msp430 data sheet, neither in the comments for the driver code. (I am very appreciated that any nice guy can tell me where to find a detail description about the registers in msp430f1611) I find following in usr/local/mspgcc/msp430/include/msp430/dac12.h #define DAC12GRP0x0001 /* DAC12 group */ what's dose this group mean? #define DAC12DF 0x0010 /* DAC12 data format */ what's the two types of format? #define DAC12LSEL0 0x0400 /* DAC12 load select bit 0 */ what dose 'load select' mean? #define DAC12LSEL1 0x0800 /* DAC12 load select bit 1 */ Another question is that: Is it a must to use DMA while using DAC for Tmote Sky?

[Tinyos-help] I want to read voltage value from Tmote
I am working on Tmote, and I am using the Tinyos 1.11 installed by the wizard downed from tinyos.net . I justrelpaced the Demosensor component by component InternalVoltageC in Oscilloscope.nc, and changed some connection names in Oscilloscope.nc and OscilloscopeM.nc .(Those two components in OscilloscopeRF) I used TOSbase to receive the signal from the other node. The value I got is between 3909~3919, but I think it's not right. Anybody have done the similar work before? What is the right reading voltage value of Tmote? If I am not correct, could you tell me how to get the right value? Thank you for your time!
