Console fills with NavX errors (NavX still works) #96

Closed vanjac closed 6 years ago

vanjac commented 6 years ago

Both when the robot is disabled and enabled, the console is constantly being flooded with almost identical messages:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/robotpy_ext/common_drivers/navx/registerio.py", line 114, in run
    self.getCurrentData()
  File "/usr/local/lib/python3.6/site-packages/robotpy_ext/common_drivers/navx/registerio.py", line 176, in getCurrentData
    curr_data = self.io_provider.read(first_address, read_count)
  File "/usr/local/lib/python3.6/site-packages/robotpy_ext/common_drivers/navx/registerio_spi.py", line 85, in read
    raise IOError("CRC error")
OSError: CRC error

Locals at innermost frame:

{ 'count': 108,
  'crc': 237,
  'data': [ 123,
            123,
... continued ...

The NavX works fine as far as I can tell (I've only tested getAngle()). But these constant errors make it difficult to debug any other problems.

The issue was actually in our code. We had created the AHRS twice.

Heh, that's an interesting effect.
