11/07/11 11:26 jec made the queue static
10/30/11 17:59 jec fixed references to CurrentEvent in RunTemplateSM()
10/23/11 18:20 jec began conversion from SMTemplate.c (02/20/07 rev)

Function
InitMorseElementsService
Parameters
uint8_t : the priorty of this service
Returns
bool, false if error in initialization, true otherwise
