On the other hand, it is still probably possible to make the sensor work, because digital NXT sensors use the standard I2C protocol, which is supported on the roboRIO. You would have splice your own connection into a NXT cable and port the driver from the old control system (probably not that difficult).
You may also want to consider using a different sensor than a compass to measure orientation because of interference from the magnets in the robot's motors. You will likely only be able to get an accurate orientation reading when no motors are running on the robot. IMO, a better option is an IMU such as the NavX MXP, or the ADIS16448 (still available in FIRST Choice). I have not yet used either of these, but I have heard a lot of praise for the NavX. The ADIS16448 is new, but it is likely also very good. |
NavX MXP no longer functions with the roboRIO. My team purchased a couple to use this year, but the 2016 firmware for the roboRIO breaks it. We have contacted the creators to ask if they are planning on fixing this, but the understanding we have is that no, it will not be updated in the foreseeable future which means it can't really be used this year...
