    Teensy 3.1/3.2 is the target, and KDS is 'Kinetis Design Studio'. A Eclipse GUI and a GNU for ARM tool chain. My hope for writing straight C or C++ code for the MK20DX256 on-board the Teensy modules.

    KDS for Teensy 3.1

    Build error DDRD and PORTD undeclared (first use of this function).
    Are the register names wrong for KDS, or am I missing a header file?

    Using functions itoa, and dtostrf

    I do an #include <stdlib.h>, but get 'Not declared in zone' error messages for these functions. Arduino says that these functions are OK, so is this a Teensy 3.1 issue?
