Hi Miklos,
Since I am new to the nesC programming this is my pseudo code to implement
this. Can you help to see I am on the right track? The lines with //new are
mine.
Thanks.
Oscilloscope.h:
===========
typedef nx_struct oscilloscope {
.....
nx_uint8_t tx_power; //new
} oscilloscope_t;
OscilloscopeAppC.nc:
===============
...
implementation
{
components ..., RF230ActiveMessageC... //new
Oscillosope.RF230ActiveMessageC ->RF230ActiveMessageC; //new
}
OscilloscopeC.nc:
===========
module OscilloscopeC
{
uses{.... RF230ActiveMessageC...}; //new
}
implementation
{
...
uint_8_t tx_power_reading = 0; //new
....
event void Timer.fired() {
if (reading == NREADINGS)
{
if (!sendBusy && sizeof local <= call AMSend.maxPayloadLength())
{
// Don't need to check for null because we've already checked length
// above
tx_power_reading =
RF230ActiveMessageC.PacketTransmitPower.get(&sendBuf); //new
local.tx_power = tx_power_reading; //new
memcpy(call AMSend.getPayload(&sendBuf, sizeof(local)), &local,
sizeof local);
if (call AMSend.send(AM_BROADCAST_ADDR, &sendBuf, sizeof local) ==
SUCCESS)
sendBusy = TRUE;
}
}
