This year, when we tried to hook up our accelerometer, The ADXL245 via I2C and our output was all 0s. After some searching on the forums, it turns out that the round DB37 cables from last year do not work and we need to use the Flat ones we got in this year's KOP.
We tried testing all the pins and they work the same for both cables (after fixing this year's cable of course). Also, we found out that the old cable actually has less resistance than the new cable. So can anyone who is awesome with Electronics find out why Flat works and Round doesnt?
The problem might be because our round cable is defective in some way because other teams have experienced the same thing.
