[Avrora] Mica2 Vs. MicaZ

[Ciaran Lynch]

Sorry for the delay, Rodolfo is correct -- the SOS micaz code sets the SPI output pins directly, while the avroraz CC2420 driver expects the communication to come through the SPI registers. Try the attached version of platform/micaz/cc2420_hal.c and see if it helps at all (rename it to cc2420_hal.c and replace the existing version). It simple replaces the direct bit manipulation with a version that uses the SPI hardware. Also if you add "-verbose=radio.cc2420" to the avroraz command line it will produce lots and lots of debugging information which should give you a good idea of what is happening.

Hope this helps,

Ciaran

But I compiled as 'make micaz'  and that works. Doesn't that mean that
my code is micaz ready? Sorry if I am missing anything :(

If you compiled against micaz then it should work. Could you check if the cc2420 is receiving any spi frame from the micro to drive the chip? 

I remember that initially SOS was not working because the SOS cc2420 driver implementation does not use the hardware SPI registers to communicate with the radio chip. However, the cc2420.java implementation in Avrora is expecting the communication via SPI frames to the cc2420. I am not SOS user so i cannot be of much help testing that.

regards,
Rodolfo.

It only works if you compile against the platform you want to
simulate. The same code will never send packets in both platforms
since they have different radio chips.

Hi,I am a little bit confused here:
When I try this:
avrora -banner=false -random-seed=100 -colors=true -platform=mica2
-simulation=sensor-network -update-node-id=true
-monitors=real-time,leds,packet,energy -seconds=3000
-sections=.data,.text,.sos_bls -nodecount=3 module_test_app.od

I see packet transmission going on among the nodes.

But, if I just change mica2 to micaz, the motes start, but no
packet transmission occurs. Shouldn't the same program work for both
platforms? (unless avrora has some issues)

I am developing for SOS.

Thanks a lot.....
