AjK 0:e2433ca2ce59 37 *
AjK 0:e2433ca2ce59 38 * The Mbed library supplies the DigitalIn and DigitalOut objects to allow you
AjK 0:e2433ca2ce59 39 * to specify ins and outs.
AjK 0:e2433ca2ce59 40 *
AjK 0:e2433ca2ce59 41 * SimpleTLE5206Output allows library objects to implement pins without the requirement
AjK 0:e2433ca2ce59 42 * to link against the Mbed library. This increase portability when using
AjK 0:e2433ca2ce59 43 * alternate compilers (such as the Code Red GCC C++ compiler for LPCXpresso).
AjK 0:e2433ca2ce59 44 *
AjK 0:e2433ca2ce59 45 * Additionally, this class allows the pin to be configured as a GPIO output or swapped
AjK 0:e2433ca2ce59 46 * to PWM output mode.
AjK 0:e2433ca2ce59 47 *
AjK 0:e2433ca2ce59 48 * Note, this class can only be used for pins p21 through p26 as these are used for PWM pins.
AjK 0:e2433ca2ce59 49 * Trying to set this to any other pin will result in a fatal error() call.
