Hi All,
I'm using the CVS version of tinyos-2.x, and I'm trying to read the ED
value instead RSSI. I used the RssiDemo tutorial as code base and I
slightly modified it to make it work with the Iris platform. The
RssiDemo perfectly works if I read the RSSI value from the RF230, but
as soon as I recompile it to read the ED value from the RF230 I always
get 0 (zero) as ED value. Do you have any tips? Have anyone used the
ED reading with Iris successfully?
Also have looked at the /opt/tinyos-2.x/tos/chips/rf230/RF230LayerP.nc
file and I have simple question, the code:
if( irq == RF230_IRQ_RX_START )
{
temp =
readRegister(RF230_PHY_RSSI) & RF230_RSSI_MASK;
rssiBusy += temp - (rssiBusy >>
2);
#ifdef RF230_RSSI_ENERGY
temp =
readRegister(RF230_PHY_ED_LEVEL);
#endif
call PacketRSSI.set(rxMsg,
temp);
}
should not be rewritten in the following way?
if( irq == RF230_IRQ_RX_START )
{
#ifdef RF230_RSSI_ENERGY
temp =
readRegister(RF230_PHY_ED_LEVEL);
#else
temp =
readRegister(RF230_PHY_RSSI) & RF230_RSSI_MASK;
rssiBusy += temp - (rssiBusy >>
2);
#endif
call PacketRSSI.set(rxMsg,
temp);
}
Ciao,
Stefano "Kismet" Lenzi
P.S.: If you think that it could be useful I will be glad to share the
modified RssiDemo code, how can share it?
