    Microcontroller for game controller

    I have seen "simple" controllers with Chinese 8051 e.g. STC and complex ones usually ARM e.g. STM32: https://de.ifixit.com/Teardown/PlayStation+Move+Controller+Teardown/3596

I am using coocox with https://launchpad.net/gcc-arm-embedded/ How do I include the newlib into my toolchain? Or am I wrong with newlib an the problem lies somewhere else? I included the syscalls from the repository: "The component implement the minimal functionality required to allow libc to link." I also included libc in the "linked libraries section".
