iriver h1x0 - RTC (real time clock) mod

[roolku]

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

I wish you success.

How do I apply the RTC patch to Rockbox?

Have a look here: http://www.rockbox.org/twiki/bin/view/Main/SimpleGuideToCompiling

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

1) you don't need to connect the pin SQW/INT to the play button pad
2) you don't need to uncomment the line

#define HAVE_ALARM_MOD

in the patch (i.e. leave it as  /*#define HAVE_ALARM_MOD */ )

But since you are using the DS3231S you won't have any startup problems, so if you feel comfortable with the soldering, you might as well have it.

Great! Thank you, very much for the reply.

I will report back on how it went. Soldering is the part I am most comfortable with, as I am an electronics tinkerer. It's the patching code stuff that throws me...

That simple guide to compling is not so simple.   Would someone be willing to apply the RTC patch to Mmmm's latest build (with the recording Enhancements) for me and post it somewhere?

Howdy TaperChuck, I'll be attempting this mod tomorrow and also want to use the Recording Enhancements Pack so if I succeed I'll give you a copy, although if we can talk the REP maintainers to put it in themselves that would be the smartest solution.

[TaperChuck]

Cool, let me know how it goes.

I know it's weird to quote oneself but here it goes:

OH MY GOD!  

I only dreamed that this was possible.  Only in my dreams could this be done.  
I will attempt this as soon as it has totally matured. This is truly amazing to me.

Thank you so much.

So now that the appropriate chip has been found that does both RTC and alarm without any installation caveats (other than the obvious ones) I would like to purchase four (4) DS3231 chips as I have three H1x0 units and want another H120. (don't ask why)

Does anyone have four chips to sell? And if so how much for then shipped to 10013?

Thanks.

Well, I installed the DS3231S and the recorder still works fine.  
I used double sided carpet tape to anchor it to the circuit board and placed a small piece of electrical tape over it before I replaced the hard drive.

I just need some help getting the RTC patched REP version of Rockbox. Anyone...

You can get the current svn (r12186) build with the REP patch from this post
http://forums.rockbox.org/index.php?topic=2513.msg65917#msg65917 and the latest rtc patch here: http://roolku.pwp.blueyonder.co.uk/rockbox_rep_rtc_r12186.zip.

Enjoy

Thank you very much roolku! My RTC is working properly, now and I'm using REP too.  Add me to the list of happy modders who have done the RTC mod.

A huge thanks to roolku for contributing such a brilliant mod!  
Thanks to Software_Samurai for been willing to ship me the chips too.

I spent the first half of the day installing VMWare and working out how to compile in order so that I could use the REP flavour.  Then I saw roolku made that too, thanks again.  Will the REP pack always support the RTC by default now?

I thought I killed my unit at one point, I soldered two legs together on the U23 chip and without the right tools it took me a lot of scratching and reheating to get it off.  After I had finished the unit wouldn't boot but after I powered it from mains things came right again, phew.  So go very easy  with your solder and try not to use too much.

In summary I am extremely pleased, I have a habit of recording lots of files over months without clearing my unit.. now I will know when it was recorded to the second!  

[roolku]

Glad it worked out for you two. I have added you to the list of successful modders.

As for the REP - the build I made is really a one-off, as the REP clashes badly with some of my other patches and I am not using it myself. Maybe you could work something out within the REP crowd?

Cheers

Touchdown. My H140 is successfully modded. I received from Maxim 2 samples, but I broke one, because I've no experience with soldering. On the same time, I replaced the battery with a iPod 2200mAh.

Congratulations! This makes 10 h1x0 players with the RTC mod that I am aware of. I wonder when we will reach critical mass for inclusion in SVN.

I just received four of these chips from software samurai and will report back here when I mod my H120 and my two H140s. Will try to get to it over the weekend. Stay tuned.

(off topic but related) did you guys see this post relating to USB charging for the H1x0?  Can any of you hardware gurus be of assistance?

I just bought an iHP-140 and plan to use the extra Maxim chip to mod that one as well.
