[Tinyos-users] no output with I2C in mica2

Hi,

I'm unable to put the I2C to work in mica2.
I've tried both the I2CM and the I2CPacketM.

I'm trying to write to an ultrasound module (srf08) this code:
       call I2C.sendStart();  //start flag
       call I2C.write(0xE0); //I2C device add
       call I2C.write(0x00); //I2C device add register
       call I2C.write(0x51); // instruction
       call I2C.sendEnd(); // end flag

The sendStartdone event is triggered but not the writedone event or the readdone.

Is there a need to do something that I'm not looking at.

I've also compiled and installed the I2CPacketTest and tried to debug it with the Leds. But the same thing happens. The writedone event is not triggered and the write call returns FAIL.

I've also tried to use the module with a simpler device - the TC74 temperature sensor. But the same thing happens - Nothing!

I would be most thankful if you could help me since I've been around this for a long time, Rafael Aranha _______________________________________________ Tinyos-users mailing list [email protected] http://mail.Millennium.Berkeley.EDU/mailman/listinfo/tinyos-users
