tony63 3:fda6508b1efc 2 reloj con ds1307 para que el circuitotrabaje bien se hacen las siguientes recomendaciones
tony63 3:fda6508b1efc 3 1. ponerle un cristal de un reloj de buena calidad no usar el cristal originalmente instalado..retirelo
tony63 3:fda6508b1efc 4 2. retire las resistencias de superficie pull up que son R2 y R3
tony63 3:fda6508b1efc 5 3.conforme un circuito externo con dos nuevas pull up de al menos 4.7k a una linea de alimentacion de 3,3v
tony63 3:fda6508b1efc 6 4 coloque diodos in4148 con los anodos a masa y cada catodo conectado a las lineas sda y scl
tony63 3:fda6508b1efc 7
tony63 3:fda6508b1efc 8 si hace esto el circuito trabajara muy bien
tony63 3:fda6508b1efc 9 antes de configurar parar el reloj y despues de configurar darle start al reloj, no lo olvide
tony63 3:fda6508b1efc 10
tony63 3:fda6508b1efc 11 el reloj se configura desde la pc
tony63 3:fda6508b1efc 12 adicionalmente al ejemplo de mbed este programa imprime en una lcd y pide el dia ya que originalmente solo se
tony63 3:fda6508b1efc 13 ajusta a un dia domingo
tony63 3:fda6508b1efc 14
tony63 3:fda6508b1efc 15 originalmente trabaja en modo 24 horas seria interesante trabajarlo a modo 12 horas haciendo uno la flag
tony63 3:fda6508b1efc 16 bool thm = true;
tony63 3:fda6508b1efc 17 de la libreria en la linea 64 Rtc_Ds1307,ccp
tony63 3:fda6508b1efc 18 los registros son en bcd
tony63 3:fda6508b1efc 19 segundos 00h
tony63 3:fda6508b1efc 20 minutos 01h
tony63 3:fda6508b1efc 21 horas 02h bit 6 es el modo 24/12 --0/1.. y el bit 5 es el indicador si la hora es am/pm 0/1
tony63 3:fda6508b1efc 22 dia 03h
