Hi, I just got a BrickPi. It’s a Christmas present for the kids but I don’t have the NXT/EV3 motors yet. I put it on my Pi to check it out and without motors or sensors, only way I could really check it’s there is to run the sample battery voltage reading script. However, this returns “FALSE”. I also notice that if I run i2cdetect utility I see nothing at all. I believe the BrickPi has some of the sensors on I2C including the reading of the battery voltage. I’ve tried both my own Raspian image but also downloaded the Dexter one and it’s the same with both. I2C bus on PI is working as I can attach another I2C device and see it.
I’ve power the BrickPi and Pi via the 2-pin power connector on the BrickPi. I’ve confirmed there’s 5 Volts coming out of the voltage regulator on the BrickPi. NOTE: There’s no lights on the BrickPi. Not sure if it has any or not.
Should I be able to see it on the I2C bus and be able to read the battery voltage? Do you think it’s a faulty unit? I don’t have the motors to test further until nearer Christmas and it would be a shame if it turns out to be a faulty unit.
