I use code form http://www.ccsinfo.com/forum/viewtopic.php?t=19926&highlight=ds1307 for 16F819 it work but why i modified that code for 12F675 it not work
original
| Code: |
#include <16F876.h>
#fuses HS,NOWDT,NOPROTECT,PUT,BROWNOUT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
#use i2c(Master, SDA=PIN_B7, SCL=PIN_B6)
#include <ds1307.c> |
========================================
modified for 16F819 it work
| Code: |
#include "16F819.h"
#fuses NOWDT,XT,NOPUT,NOPROTECT
#use delay (clock=4000000)
#use rs232(baud=2400,xmit=PIN_A2,rcv=PIN_A3)
#use i2c(Master, SDA=PIN_B1, SCL=PIN_B0)
#include "ds1307.c" |
========================================
modified for 12F675 it not work
| Code: |
#if defined(__PCM__)
#include <12F675.h>
#fuses INTRC_IO,NOWDT,NOPROTECT,NOMCLR,PUT
#use delay(clock=4000000)
#use rs232(baud=2400,xmit=PIN_A5)
#use i2c(Master,SDA=PIN_A0,SCL=PIN_A1)
#include "ds1307.c" |
i connect
12F675
pin1-->gnd
pin 2-->TX
pin6-->SCK(ds1307 pin6)
pin7-->SDA(ds1307 pin5)
pin8-->vcc
ds1307
pin1,pin2-->OSC 32.768 K
pin 3-->3v
pin 4-->gnd
pin5-->(12f675 pin7 pull up)
pin6-->(12f675 pin6 pull up)
pin8-->vcc
i so confuse why it not work on 12F675 (it not send anything to hyper or lcd) but it work on 16F819
PS. sorry about my english skill and thank you for your help
