hi.. need help for my final project can someone teach me about assembly code of ds1307??? thanks..sorry if my english so bad... RGDS...
Greetings from Mexico Can you help please with ASM or C code to use the Time Keeper Maxim DS3232 with PIC16F and PIC18F micros. It is noteworthy that the DS3232 is better, much more accurate, does not require of 32.768 kHz XTAL because it has integrated into the package and is replacing the ds1307. The trouble is that no code on the (...)
can anyone send to me the source code for digital alarm clock with alarm using PIC16f877a,ds1307 and lcd. i also need the schematic diagram for the circuit.i`m using mplab ide..thank you very much.

m41t00 from ST I2C c code for pic: HH NeuralC
Hi, Does any one knows that the codeVision for AVR use Hardware or Software I2C in Automatic Program Generator OR its include I2C library? Like the ds1307 library is using Hardware/Software I2C? thx
for ds1307 download the code for melany newman code for pic work very well i Just prove
Have a look at this project: "How To Build a Talking Time & Temperature Display With The CCS C Compiler" You can try to use sections of C-code which are relevant to your project .. Regards, IanP
I am pretty sure the code you already have does exactly what you need .. plus a little bit extra .. Try to remove sections which send data to LCD and generate alarms .. Regards, IanP
for ds1307, the exact code of 24C0x (the I2C eeprom) works perfectly. Both are I2C devices.
there are i think over 200 rtc maxim chips ive personaly written 5 for proteus vsm what one??? some two some three or more wire comms wtf do you mean help ?? with asm i think what you wanted to post was " will someone who is also an idiot but knows far more than me do my donkey work for me i cant be bothered and just ask
i have this code for ds1302 with pic16f876, wich is a part of a led moving sign, for real time clock, i give as is. excuse my english, i can't give more details caus my bad english.hope that help.
hi!!! The only changes i made are as below #define RTC_SDA PIN_B0 #define RTC_SCL PIN_B1 and this is codes #include <18F4550.h> #fuses HSPLL,USBDIV,PLL5,CPUDIV1,VREGEN,NOWDT,NOPROTECT,NOLVP #use delay(clock=48000000) //,RESTART_WDT #include <ds1307.c> #include #define LCD_RS PIN_D0 #define LCD_RW PIN_D1 #
Dear Friends, I have 2 microcontrolles Atmega16 and Atmega8 connected in I2C configuration. and RTC ds1307 also sharing I2C connection. Master is Atmega16 and remaining two are slaves. I have done interfacing using I2C between Controller and RTC,bt i dint do for two controllers.ds1307 will have its own address for (...) we have the sponsor......Just posting the code will do nothing. Guess the OP will ask for Complete description of the code, Flow charts, PCB layouts, and project description too. Be ready for that too. Celebrating with bottles of Champagne...Cheers
Hi rashidali.. U have developed code for calender using RTC... so now u have to just take data from user using keys...and as per the data entered by user u have to set parameter in RTC... read RTC continuously and print on LCD...
Hi, Your SCL and SDA lines for I2C are in PORTC, so if you want to use PORTD, use the software I2C library provided in mikroC. They have a code for RTC in the examples, but they use the PCF8583 RTC instead. Take a look there. Take a look at the software I2C library and the links I provided. The first one should be very helpful. picnote.b

I have count encoder pulse on interrupt RB0 here. You may change RB0 input to count push button pressed.
It' looks to me like a simulator problem, but don't use mikroC and thus can't further check the behaviour of your code.
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 (...)
I am a new user...I need to work on a project using 89C51 & DS 1307... i wanted to know the C code for basic reading and writing into the RTC(DS 1307) as im quite unfamiliar with it..

Hello I need C code of I2C bus for LPC2138
Please give me information about I2C protocol and programming examples for ds1307 and EEPROM 1024 in assembly language. Thank you Sangmeshwar The IIC code is inthe topic have uploaded the ds1307 IIC communication code in ASM. Regarding IIC protocol, please read an
I would ignore what is in the registers by default and init them to some arbitrary value that results in somtlhing like jan 1 2000. If your clock keeps time when the device is off (via battery) you can store a known byte to an EPROM location when you run the "first time int" code. That keeps you from clobbering a real time value.

hi all.. i'm working on project creating datalogger using AVR ATMega8535, i using RTC ds1307 conect to AVR : SDA --> PB0, SCL --> PB1 for time stamp and store log data using EEPROM 24C256 , code for RTC i create using CVAVR that have built in code to run RTC ds1307 and it works, but (...)
you can write you own code to get the system time and date ... and then this data can be outputed to the serial port using any language like c.
manarose ds1307 is real time IC with I2C protocol hi,I haven't used PIC to control it yet.But I have use AT89Sxx to control it. here are my code. hope it helpfull to you #include "REG52.H" #include "REG52.H" sbit SDA = P1^0; sbit SCL = P1^1; //declare function void delay(void); void SCL_high(void); void SCL_low(void); void I2C_St
the at24c256 is working properly the only error that i get is that after sometimes(about 2 or 3 weeks) the CH bit will be disabled (tie to 1) and i don`t know why? i use bascom to write code for my atmega16 and i defined i2cdelay=10 (100khz clock) for ds1307 data transfer and i2cdelay=1(400khz) for at24c256 (...)
i am using RTC ds1307 and EEPROM AT24C02 - both are sharing same I2C lines. so how can i differentiate them in codeing and data transferring.??
well, i'm a little confuse about how to set the real time in rtc by assembly code that i want.... 'coz from i read , we have to set the time before we use ds1307... If someone has the code, could you show it in this topic?? it will great if commented...thank you RGDS jandreas
