dannyman939 0:c746ee34feae 29 This example shows how to use the new callback system. In the old system
dannyman939 0:c746ee34feae 30 Mbed's FunctionPointer[1] type was used to store abd make calls to callbacks.
dannyman939 0:c746ee34feae 31 However, that limits the callback function prototype to void func(void);
dannyman939 0:c746ee34feae 32 which means we cannot pass parameters.
dannyman939 0:c746ee34feae 33
dannyman939 0:c746ee34feae 34 This latest version of MODSERIAL now uses its own callback object. This allows
dannyman939 0:c746ee34feae 35 the passing of a pointer to a class that holds information about the MODSERIAL
dannyman939 0:c746ee34feae 36 object making the callback. As of version 1.18 one critcal piece of information
dannyman939 0:c746ee34feae 37 is passed, a pointer to the MODSERIAL object. This allows callbacks to use the
dannyman939 0:c746ee34feae 38 MODSERIAL functions and data.
dannyman939 0:c746ee34feae 39
dannyman939 0:c746ee34feae 40 Additionally, since MODSERIAL and the callback parameter class MODSERIAL_IRQ_INFO
dannyman939 0:c746ee34feae 41 are friends, MODSERIAL_IRQ_INFO can access the protected functions of MODSERIAL.
dannyman939 0:c746ee34feae 42 This is used to ensure functions that can only be called during a callback
dannyman939 0:c746ee34feae 43 can be invoked from a callback.
