Hello,

I am planning to interface an LCD Panel to the expansion connectors of TMote
Sky. Can someone suggest me how to go about connecting it and programming
the mote to display some printf statements.

Thanks for the reply. I still have some doubt regarding this interfacing.

Assuming i buy an I2C interface, what are the further steps to get it
working? Like for example, if i have to blink LEDs, i can call
Leds.Led0Toggle( ) and either switch on or switch off the red LED. So how do
i do something similar for writing to pins of the LCD interface?

Regards
Preethi

 The only thing I can tell you is to try the I2C interface.

There should be displays with this interface on the market. Here they are
about 2 dollars each.

[Tinyos-help] Connecting an External Antenna to TMote

[Preethi Naveen]

Hi,

I am interested in connecting an external antenna to extend the range of tmote. I have been through the tmote data sheet which explains shifting of the capacitor for external connection. I would like to know if issues such as impedance matching of antenna is taken care of if i use the SMA connector supplied by digilink. Any other precautions/tips towards connecting an external antenna would be very helpful.


Thanks

[Tinyos-help] Receive Power in Tmote Sky

[Preethi Naveen]

Hi,

As per the data sheet of Tmote Sky, the power consumed during reception is more than the power consumed during transmission. Is it because Direct Sequence Spread Spectrum (DSSS)is used in the CC 2420 radio used in tmote? So does it mean that using a radio that uses DSSS consumes more power or is it some design deficiency of tmote/CC2420 radio chip?


Thanks
