ESTE PROGRAMA TOMA UNA CADENA DE GPS NEMEA Y CREA LA CADENA QUE EN GOOGLE MAPS SE ABRE EL MAPA INDICANDO LA GEOLOCALIZACION lA LIBRERIA GPS, FUE MODIFICADA EN LA ESTRUCUTURA DE DATOS, PARA RECONOCER LA VARIABLE (LOCK)DEL GPS QUE INDICA SI LOS DATOS SON ACEPTABLES EL PROGRAMA SE PRUEBA CON EL GPS VIRTUAL DE PROTEUS Y SE INYECTAN LOS DATOS A UNA FRDMKL25Z ATRAVES DE UN DONGLE QUE SE VINCULA DE FORMA LOGICA AL COMPIM DEL PROTEUS

ESTE PROGRAMA TOMA UNA CADENA DE GPS NEMEA Y CREA LA CADENA QUE EN GOOGLE MAPS, SE ABRE EL MAPA INDICANDO LA GEOLOCALIZACION LA LIBRERIA GPS, FUE MODIFICADA EN LA ESTRUCUTURA DE DATOS, PARA RECONOCER LA VARIABLE (LOCK)DEL GPS QUE INDICA SI LOS DATOS SON ACEPTABLES. EL PROGRAMA SE PRUEBA CON EL GPS VIRTUAL DE PROTEUS Y SE INYECTAN LOS DATOS A UNA FRDMKL25Z ATRAVES DE UN DONGLE QUE SE VINCULA DE FORMA LÓGICA AL COMPIM DEL PROTEUS. LAS CONEXIONES LA MUESTRA LA FIGURA DE ARRIBA, SI SE DESEA INCORPORAR A UN RASTREADOR SATELITAL. EL LED VERDE SE ENCIENDE SOLO SI LOS DATOS SON ACEPTABLES, LAMENTABLEMENTE EL GPS DE PROTEUS NO MODIFICA LA CADENA, SI SE CONFIGURAN MENOS DE TRES SATÉLITES EN VISTA.

LA CADENA RESULTANTE AL ESQUEMA ES LA SIGUIENTE. EL CENTRO DEL ESTADIO ATANACIO GIRARDOT, EN LA CIUDAD DE MEDELLÍN - COLOMBIA.
