    Building a Raspberry Pi robot with the A-Star 32U4 Robot Controller

    - 4 January 2017

    Hello,
    I will combine a RasPi Zero and the Zumo32U4. Now I have trouble with point 2 from your tutorial.
    I made some changes in the arduino sketch to make it compatible with the Zumo32U4 library. "AStar" changed to "Zumo" and "readBatteryMillivoltsLV()" changed to "readBatteryMillivolts()"
    Now I stuck at the compiling process.

    The following error occurs:

    Arduino: 1.6.13 (Windows 7), Board: "Pololu A-Star 32U4"
    libraries\Wire\utility\twi.c.o (symbol from plugin): In function `twi_readFrom':
    (.text+0x0): multiple definition of `__vector_36'
    libraries\PololuRPiSlave\PololuTWISlave.cpp.o (symbol from plugin):(.text+0x0): first defined here
    collect2.exe: error: ld returned 1 exit status
    exit status 1
    Error compiling for board Pololu A-Star 32U4.

    Please can you explain how i fix this problem.

    -Peter
