No need to wait after Wire.requestFrom() and it should not be followed by Wire.endTransmission().

[Koepel]

The usage of the Wire library is not okay in these files:

• boat-systems/hardware/compassAndRudderInterface/firmware/autopilot/libraries/LIS3MDL/LIS3MDL.cpp
• boat-systems/hardware/compassAndRudderInterface/firmware/autopilot/libraries/LSM6/LSM6.cpp
• boat-systems/hardware/compassAndRudderInterface/firmware/autopilot/libraries/L3G/L3G.cpp
• boat-systems/hardware/compassAndRudderInterface/firmware/autopilot/libraries/LSM303/LSM303.cpp

There is no such thing as a timeout after a Wire.requestFrom().
The Wire.requestFrom() should not be followed by Wire.endTransmission.
Explanation: Common-mistakes, number 1 and 2.
See also my alternative explanation of the functions of the Wire library.

Thanks for the comment. Those are not my libraries, but I will check if there are newer versions.

Is Pololu the original author of the code? I wanted to create a issue over there, but I already did: pololu/zumo-shield-arduino-library#1

@Koepel I don't remember where I got those files from. It has been a couple of years. But, it probably was them. Thanks again.
