by missed call motor switch on
Hi guys,
i want to design a system for my motor control,such that when i give missed call from my mobile to the mobile at receiver end it blinks with the light .THis light is detected by LDR which gives appropriate signal which is fed to microcontroller and it...
Re: RTC display problem
Hi i am from Shimoga,doing my enggineering in bangalore.
well reading of rtc register is still a question.
because even after disconnecting rtc in ISIS simulation it still displays 00:00:00 SUN 00/00/2000
please help?
Re: RTC display problem
Thanks a lot vishwanath for your reply.
the solution you have given to generate i microsecond delay was really helpful.
did your real time value displayed on lcd?
the thing is even after disconnecting rtc i am getting the display as 00:00:00 SUN
00/00/2000
I dont think...
hitech
Hi I am using HitechC .and i am using PIC16F877A.
I want to make a digital clock.
this is the code given below.
when compiled there is no error,but its not displaying time and date.
#include<htc.h>
void _nop_(void);
#define delay_us _nop_(); //generates 1 microsecond
#define LCD PORTD...
rtc i2c in milliseconds
I am not that sure about I2C protocol functioning.
I have not used I2C bus i just directly connected sda and scl pin to microcontroller's sda and scl pin i.e.,RC4 and RC3
the DS1307 device address i am not sure.if you are asking the slave address then it is D0 during...
proteus and rtc
ya i I2C is a serial bus used to communicate with peripherals.
BCD is a binary coded decimal format.
my problem how to address the register contents stored in RTC.
please help:?::?:

Thanks ,i have gone through the RTC datasheets ,but still i am facing problem in understanding it.i tried manipulating many programs available in internet.but still i am not successful.please help:?::?:
Hi,everyone I am using RTC DS1307 and interfacing with PIC16F877A .I dont no how to read RTC register value i.e.,date and time information on LCD.Help me out.If anyone possible give the source code in C.
I am using MPLAB IDE with hitech C.
I have gone through I2C protocol given in DS1307 datasheet ,but i am unable to understand it.My problem is i am using ds1307 interfaced to PIC16f877A.and i want to display the time and date value on LCD-HD44780.
Anyone help me out..:?::?:
