Hai, now i am doing program for interfacing ds1307 with lpc2148 using I2C communication protocol. i got this code from net but it is not working properly. the output is like 00:00:00 then in next line 00-00-00. i think that program have some minute error please clear that. or else if u have some other program kindly (...)
Hi I have a code for interfacing the ds1307 time IC with pic and LCD the code works fine and it has 3 buttons to adjust the time and other what I want to do is to add 3 buttons to allow user to enter the wake up time and compare it with the real time so that it can start a buzzer when there is a match the problem is (...)
you have many sample codes on
Hello there, I am working on RTC ds1307 using pic18f87k22 controller from few days but i dont know where i go wrong. I search most of the website but didnt get the solution. Here i post my code can you please trace out where are the problems. #include #include void delay(void); signed char ack=0; unsigned char
Year 1989 You can set only 00 to 99 19 set in manually in the source code There is no "19", the year settings refer to 2000 - 2099 and the programmed leap years are for 2000-2099, not 1900-1999

hello, in your program , you forget the day of the week ! add this variable and treat it in your program.. #define ds1307_ID 0xD0 #define SEC 0x00 #define MIN 0x01 #define HOUR 0x02 #define DOW 0x03 <- Day of week #define DATE 0x04 #define MONTH 0x05 #define YEAR 0x06 example: void ds1307_get_date(void) { I2C
Hello, The above code looks fine. Where is the main file? How are you sending commands to the device? There is no issue with the clock rate. Even you can read the device at 10Kb/s rate. Enjoy!!!
New file attached. Post code of btoa() function. while(1){ readds1307(); Transform_Time(sec, min1, hr, week_day, day, mn, year); Display_Time(sec, min1, hr, week_day, day, mn, year); lastdate_check(day, mn, year, last_date); lastmonth_check(day, mn, year); lastyear_check(day, mn, year); }
Hi Friends, I have written C programme for RTC ds1307 interfacing with at89c51 and just want to see this time in PC Hyper Terminal using RS232. but in hyper terminal I am getting some garbage value. so anyone can say me that what would be error in that program. if anyone want to see code it is in below

Zip and post MPLAB project files and Proteus file for quick solution. I don't have time to create new projects for every code posted asking help. remove this second while(1); at the end of code. The code stucks execution stucks at 2nd while(1) loop and never comes out.
Thanks Jayanth, yes, I use mikroC Pro, the part of code: char filename = "BROJAC0x.TXT"; // File names // Creates new file and writes some data to it void M_Create_New_File() { filename = '1'; Mmc_Fat_Set_File_Date(2013, 9, 21, 9, 0, 0); // Set file date & time info Mmc_Fat_Assign(&filename, 0xA0); // Find exi
hello, to add a delay of 0,5sec you can use the output 1Hz of ds1307 square forme 0,5sec ON , 0,5sec OFF and link to an unsued input ex : RC2 char temp; While(RC2==0); // wait for rising edge T0CON.TMR0ON = 1; TMR0L = 0; TMR0H = 0; while(PORTCbits.RC2==1); // Wait for 0.5 sec T0CON.TMR0ON = 0; (...)
hi frnds here i have a problem - how data write and read in rtc (ds1304) . micro controller is at89s52 is used... how can i write and read data from ds1307 .? and is there any assembly code for it... thanx..
hello, i have a written code for ds1307 in pic18f46k20 using i2c master mode. i tried a many code .but it not work? can i get proper code to read the second ,minute from ds 1307 and write into ds1307?
Hi, The datasheet for that chip shows the program flow and timing diagrams for communicating with a micro. It used its own serial communications convention so you will have to write all your own Pic communications code. Assembler or C ? The more popular Maxim ds1307 RTC chip uses a standard I2C interface, though you (...)
Hi, Find the attached code files for ds1307 RTC IC and I2C interface for pic18f252. It is written in Hitech PICC. To use change the extensions, headers and include files. Enjoy!
Hello guys, Do you guys have experience with ds1307 and PIC 16F877A ? I 'm using Hitech C and I can't use the example from compiler....

Dear all, I have an msp430g2553. please share code example for interfacing ds1307 with mspg2553.i am using code composer studio as IDE.
i need a heip in building c code for displaying RTC value serially using ATMEGA 32 microcontroller . please heip me out as soon as possible
What about use MUX. In that case you need to share time to communicate with ds1307 and SD Card. And you need to have write some code to control the mux depending on the necessity of operation. - - - Updated - - - there is another solution. you can use software driven IIC communication. follow the link: [URL="www.mi
I want to display the counts of seconds for each 10 seconds. It works as: when second reaches 10, the count=1, but when the second reaches 14 the count becomes 2 and 3 at 20th second and so on. Can anybody solve this problem........? the code is : "div=I2CData/10; //here I2CData is seconds cnt=div;"
hi i am using ds1307 (RTC) with atmega 16 ,complier is code vision avr. i am using proteus simulation software. In my code i need to read the date/time from ds1307 to display in 2x16 lcd. i have given option of time/date change that my problem is start, when i made any change in date/time ,the value (...)
Hello! Please check the attachement and tell me what is wrong with the code. RTC value is not displayed on LCD.
this is my first attempt for I2C and i am experimenting on ds1307 with pic 16f876A. i have written a code just to read seconds on an lcd by displaying the complete byte. i am writing 0 value to the seconds register before while loop so that the oscillator starts. then in while loop i am reading the seconds register(reg0) (...)
Hi, I am here after a serious failure in all my practices done for the interfacing with ds1307 RTC. First of all I would like to tell you that, I have successfully compiled my code in C for AT89C2051 to communicate with ds1307. I have tried it in Proteus VSM and run successfully. But now (...)
hi...i am trying a c code for rtc using pic...almost i have done,i have done all function in i2c....can any one tell that,after sending a data or address, we have to call ack funtion or will call automatically..after sending..below is my code..can any body suggest me.... unsigned char read_ds1307(unsigned char address) { uns
Hi friends, I am doing a Digital Clock using RTC ds1307 and 89C4051 micro controller. Time is displayed on LCD and different alarms can be set through 3 switches. I have written the following code for updating RTC registers first time. Only minutes code is shown //Minutes min++; if((min>15)&&(min<20)) { (...)
Go through these: Hope this helps. Tahmid.
Stop typing in sms style... It may happen due to the delay's in display. Post your schematic and code to find out the exact reason for the problem

Hello Everyone, I have been working on this code for a number of weeks and it is still not working. The area of concern is the PIC16877A interface to the RTC ds1307. With the Pic Kit2 debugger hooked up in MPLAB the program gets stuck the second time it enters the WaitMSSP loop waiting for btfss PIR1,SSPIF. When (...)
hi. below is my code for interfacing ds1307 with pic16f877 i am using hi-tech with mplab .i am having an issue that i always get 00:00:00 on time and 00/00/2000 on date no matter what value i initialize the time and date to. this code is part of my fyp and i have been strugling with it for quite a while (...)
Are you looking to use a Real-Time-Clock module to keep the time (for if power is cut to your module)... I2c RTC's are easy to communicate with, I've got some sample code I used on an 877 to start if this is a way you might go... Kind regards NEAL
Hello All i am working on RTC ds1307 and getting problem. i am using built in library of ds1307 in codeVision AVr. The problem is that when i start program it works fine. but after some time time got wrong as 31:05:30 and data like 01-15-13. and seconds runs as usual. i am using Atmgea16L
