[SOLVED] DS1307 code is not working

[jayanth.devarayanadurga]

Test each module seperately like first test LCD code then test RTC and LCD code... Without OpenI2C1() your RTC will not even run.

Thanx for the reply I tested the LCD code it works fine. But still I can't find a solution for the RTCC. This is the link where I found the source code for the RTCC. They faced a similar problem too. But I can't understand what they have done to rectify it.

Zip and post your Proteus file. I will check why RTC is not working. Where have you set config bits in code?

 

[ADGAN]

Sorry for the late reply. I attached all the files necessary. I'm not sure whether it will compile in your PC. I set the config bits in the configuration bits window in MPLAB.

Post screennshot of your circuit. I don't have Proteus 8. I can't open your file.

I have used your LCD files and my RTC file. I have placed all code in main file. I have modified your lcd code a little. I have compiled code for PIC18F45K22 at 4 MHz external clock.

Thank you very much. I'll try this & let you know whether it works or not.

When you used multiple source files you have to use extern specifier for variables and functions when it is referenced or used in main file.

Edit: I saw in your project's main file that there is some code outside while(1) loop of main() function. Those code will never get executed.

 

[ADGAN]

Thanx. I did that on purpose. I wanted to execute only up to that part. I will change it later. Can you explain me how to use the extern specifier? I checked your code and my one. Both works. But both get late to increment time. It takes about 5 seconds to increment 1s . I think may be something to with the delays.

 

[jayanth.devarayanadurga]

Mine increments every second. I have tested it. I have not used any delays in the code. Maybe there is delay(s) in your code. Read some C book about using extern specifier.

Without putting my code I used the hex file you gave me on the attachment. It takes some time (about 5s) to increment 1s. Don't know whether something wrong with the simulator but previously it worked properly. Which version of Proteus are you using?

 

[jayanth.devarayanadurga]

Proteus has nothing to do with the hex file. I have used 4 MHz clock freq. What clock freq are you using? I am using Proteus 7.10 SP0.

 

[ADGAN]

I'm using the same.
