Re: ADXL345 accelerometer problems

Hello all,
We are having the same problem. We are using Java, and I can see traffic on the i2c bus with a scope, but no way to decode it. Signal integrity looks ok, clocking as expected and I can see packets, but no analyzer to decode the traffic.

Symptom is no values returned. We don't have labview and so far I am unable to find the wiring diagram or any diagnostic. Based on this thread I also tried both flat and round cables between cRio and side car.

I used the code in one of the threads and it is simple enough that shouldn't be the issue.

If anyone has it working can you post a photo of the sidecar wiring?

Also, do we have to provide our own pullup resistor on CS? The datasheet says one is required for i2c, but it an external one does not seem to help the situation. Could be two problems though.

Thanks in advance!

Bob
