Using the 3-axis Serial Accelerometer from sparkfun

Hi,

I’m trying to integrate the 3-axis Serial Accelerometer with my device. I’m running NutOs on atmega1280. I set the accelerometer to binary mode and try to send it the start character ‘S’. However, the accelerometer is not responding to that command unless i unplug it from the board and plug it back in. Once I do that, everything seems to be fine.

Anyone have any idea why this is happening? I know that my code works and the hardware works because once I unplug the accelerometer, I am able to see the data spiting out…

Thank you in advance for your help.

Regards,

John
