iriver h1x0 - RTC (real time clock) mod
Davide-NYC:
OH MY GOD! :o
I only dreamed that this was possible. Only in my dreams could this be done. :D
I will attempt this as soon as it has totally matured. This is truly amazing to me.
Thank you so much.

The mod looks mature enough to me :-) Kudos to roolku.
I went on Maxim's web site and I got confused about what part number to select. I wondered what was the difference between DS1339C-2/DS1339C-3/DS1339C-33 and then I figured that "-2"/"-3"/"-33" was standing for the voltage supply required by the chip ... ::) As indicated by roolku's wiki, you need to get a 3.3V compatible chip and DS1339C-33 should fill the bill.
roolku:
I am glad you all like my little addition to the h120 rockbox. :)
I have now added the missing wake-up alarm function (optional - one additional connection) and will see if my h120 will wake me up tomorrow. ;)
Wiki and patch tracker have been updated.

I'll keep testing and working on it, but I doubt the hardware bit will change. Both, my h120 and my h140, are now modded.
--- Quote ---Just curious of the safety issues with this, would it hurt the device if I had the timer installed and was running with an unpatched version of Rockbox? Or would it just not have the clock functionality?

Without the optional wake-up alarm part, the hardware is completely dormant and has no impact. OF or unpatched rockbox run without problems (and without clock functionality).
With the alarm mod you will need to run a patched rockbox at least once after each power loss (i.e. battery dead).

;D Request for samples sent into the company! Hopefully by this time next week I can post how my attempt went. Thank you so much for doing the research into this very useful mod!

Congrats, that hack looks awesome.
Now you need to nag the swedes to have it commited and put on the cvs build page (the 8mb ram hack for the archos models is there so you have a chance :)
