Hi all,
I am trying to interface a tmote with a cyclops camera. I am using the
10-pin expansion connector of the Tmote for powering the cyclops and
using the I2C pins for communication. No other pins are connected
between the two devices. The mote is the master and the cyclops is the
slave device

Have you placed I2C pullup resistors in your design?

To Philip,
I am using Boomerang as the I2C interfaces are compatible with the tmote.
To Joe:
I was not aware that I had to have I2C pullup resistors. My current
design does not have any. Is there a schematic which shows the
placment of the resistors?
Thanks,

Please see the I2C specification. You need a 10k pullup resistor on
SCK and SDA (the SDA pullup is already on the board, the SCL resistor
is the one that you must provide)

Hi Joe,
I tried with the pullup resistor on the SCL lines, but still couldnt
get any response on the Cyclops side. I then viewed the i2c clock and
data signals on an oscilloscope once with the tmote connected to the
cyclops and then with a micaz. The signals appear totally different in
the two ca
