Thanks Enamul,

I am reprogramming them right now.

Hi Enamul,

I have reprogrammed the chips and the Master says "Master RTC Unit" but the Slave still says nothing /

thanks

Hi Stuart,
Even if any issue in other stuff..you should at least see Time and date written in LCD. Please check your RTC module connection. I can't get anything wrong anywhere.

Hi,
Have you used pull-up 4.7K resistors in SCK and SDA for RTC module?

Hi Enamul,

I can't see anything wrong with the rtc connection , I have just put the pull up resistors in but still the same.

I am uploading some pics

thanks

Hi stuart,
Can you just test your slave module like the one you have posted before..

Ok,

I will put the rtc module back on that breadboard and try it

thanks
Acestu

Success at last RTC module 1 wire in wrong pin....

Thanks
Acestu

Ok. great!
Is your CAN bus now connected?We should be able to see Time and Date in Master as well.

The Canbus is all connected up but the Master still says "Master RTC Unit"

Do the unused terminals on the MCP2551 need to be grounded ?

Also I have 100 ohm resisters on the Canbus thats what I used on the other unit

thanks
Acestu

You have tested CAN transmission earlier between Master and slave using LM35Dz as far I can remember..connection of CAN bus should be same as that..only addition is RTC module in slave which is working fine now.

OK, I have checked all my connections and found both mcp chips pins 5 to 8 back to front, I changed them and now it is sending info and returning info

Last time you did so..can you please check now MCP 2551 wiring and way it positioned.

As far as I can see Enamul, I have the Can bus set up the same as last time, I am enclosing a pic


thanks

Should the Tx and Rx of the mcp chip be connected to the 4580 via 220 ohm resisters ?


thanks
Acestu

OK Enamul, I grounded pin 8 on both mcp chips and now I have date / time on both units, however I still see the "it" where "Master RTC Unit" was


thanks
Acestu

Sorry I was feeling so sleepy that went to bed..

Should the Tx and Rx of the mcp chip be connected to the 4580 via 220 ohm resisters ?

That doesn't make too much difference.

I grounded pin 8 on both mcp chips and now I have date / time on both units,

It should be in the diagram I have posted earlier. PIN 8 must be grounded. That's great that you can see time in both unit.

however I still see the "it" where "Master RTC Unit" was

I don't realize what you mean here.

Hi Enamul,

Yes I think all it is, the words "Master RTC Unit" that are on the master unit are not cleared when the date and time start so that the last letters ie "it" are still visible on the screen, that's all I meant. I think if I shorten it to "Master RTC" in the code you should no longer see it.

thanks
Acestu

Don't worry..It's pretty easy problem. I will correct code when I will back home. Great work. Well done
Now we are ready for MIAC

Ok thats great Enamul


thanks
Acestu

Hi Stuart,

Here is the final without display issue..Please test that and let me know. I am going to make new thread for MIAC. Do you have your MIAC in hand already?

Hi Enamul,

I will do that now, also I have the brand new shiny MIAC right next to me ready for action.

Thanks
Stuart

Hi Enamul, that has done the job

Thanks
Acestu

Excellent Work! You have done it!

WoW brilliant, Thank you Enamul, I will break out the champagne,

The Guinness book of records have been on the phone, we have broken the longest ever thread on a Forum World Record lol....

Thanks
Acestu

Been an interesting thread to follow.
Got my own ideas based on this, once I have finished another project.

Thanks John,

that sounds interesting, I will post the final drawings and pics on this thread when I have finished part 2.

Thanks
Acestu
