Nessa primeira parte do projeto, o programa ainda não recebe sinais externo, seria apenas impressão de dados no lcd mesmo...
Agora a tarde retirei o circuito POR do reset e coloquei nesse apenas um resistor de 10k ligado a fonte e um capacitor de 100nF indo para o terra... com isso o programa deixou de travar, contudo ainda permanece o problema na inicialização, só começa a mostrar as imagens na tela quando eu encosto nos pinos onde está o cristal...
