iriver h1x0 - RTC (real time clock) mod

[roolku]

Success! My little H120 now has a real time clock! >woot!<

Great! I have added you to the list of successful modders on the wiki page.

Got a couple of sample chips from maxim in the mail today. Will try to get to the mod this week, but might have to wait 'til next week to find some time.  Thanks roolku for putting in the groundwork and to jmdearras for the extremely detailed photos - they should come in very handy for a noob like myself.

I need that mod. Where can I buy in Switzerland or Europe a DS3231S ?

[TaperChuck]

I just ordered some samples of the DS3231S chip from Maxim. I may have some questions after they arrive and I decide whether I want to do this mod or not.

What a mind blowing excellent mod!  

I live in Australia and am trying to get my hands on the DS3231S which is proving almost impossible, Dallas wants $50 to ship internationally, local provides want a minimum order of 20 pieces at $8 each.  Can someone suggest where I can get a few at reasonably costs or alternatively be prepared to sell and post a few to me directly please?

Ok, so I finally got enough time to do some more testing getting it to work for me. I have the first chip, and I had gotten the time to work but not the alarm. Even with a correct build, the play button was doing the rapid press thing. Today I had and idea and set the alarm to a specific time and enabled the alarm, and then soldered on the wire to play. Now both the clock and alarm are working without the problem of the play button.

So I think it would be a good idea to make it a bit more plain that you not only need the correct build, but also have the alarm enabled before you hook up that last wire.

But altogether I now have an entirely working rockbox with both the Clock and Alarm. THANKS MUCH!

Good to hear another success story.
I'll amend the wiki when it's back up.

If you work for a university or a company that's somewhat electronics related you can probably get away with ordering free samples (I did). Otherwise maybe you can get in contact with Software_Samurai:

wiki?

[pilot000]

I received 2 samples from maxim today for free (sent to switzerland). Now I have to wait until my new 2200mAh battery arrives. Then I will apply the mod to my player. Thanks in advance for the detailed illustrated instructions.

[TaperChuck]

Once the chip is installed and the software recognizes it, how do you set the correct time and configure it?

[pilot000]

in the menu: "System Options / Time and Date / Set Time/Date"

[TaperChuck]

Thank you.

I can't find the wiki that was refered to earlier. Is there more information there?

Thanks again!

I just got the DS3231S chips today. I'm going to start working on the mod this weekend.

How do I apply the RTC patch to Rockbox?
Also, I don't want to use the alarm feature. Is there something I have to do special?
