To complete my previous post, I guess my code is bad, but I don't know
where and why. In fact, I can follow the execution of the code (with
debug leds) until the first call of "I2C.sendCommand();" in
I2CPacket.write() in Atm128I2CMasterPacketP.nc. But after this function,
the program never enters in "I2C.commandComplete()" and that's where I'm
lost. Also, the "hasStart();" function return TRUE, when I include it
before the call of "I2C.sendCommand();".
So, I checked today directly on the hardware with a digital oscilloscope
to watch the frames on the I2C lines, and I saw nothing, which is
confusing me more than before.
If someone could give me a hand on this...
By the way, I saw a program TestMag for tinyos-1.x, so I wanted to test
it ; I installed tinyos-1.1.0 and the CVS update to 1.1.15 but I can't
compile it for IRIS motes (unknown target), and there is no iris folder
in /tinyos-1.x/tos./platforms/
If you have a hint on this too...
Thanks in advance,
Raphael
