Tenes un problema con la declaración de la función de interrupción, así que adentro de ella no vas a encontrar nada que te ayude. Leé el manual del XC8 para ver como se declaran las rutinas de interrupción y como se mapean al vector correspondiente.Otro detalle que se me pasaba es que si quito la palabra tiempo en
void interrupt TIEMPO (void){ el programa compila pero no funciona y cuando intento hacer el debug no me deja poner el breakline dentro de esa subrutina por eso no puedo ver donde esta el error..
int main( void ) {
....
}
__interrupt (low_priority) void getData(void) {
if (TMR0IE && TMR0IF) {
TMR0IF=0;
++tick_count;
}
}

Por que parece que ese código es generado automáticamente con la herramienta Flowcode.Además, no veo por qué razón intenta meter bibliotecas de punto flotante. No veo en tu código nada que necesite hacer cálculos con punto flotante. Si puedes ir a las opciones de compilación e indicar que no quieres que las incluya, mejor.
Mira la línea anterior y verás que falta terminarla con punto y coma ";"PCWHD Compiler dijo:*** Error 76 "PRUEBA LUCES.c" Line 123(7,15): Expect ;
