Topic: Iriver H120 mod to add a real-time clock

[IpaqMan]

I did not see any posts about the new RTC mod for the H120 here, so I thought I would post a link to it here.

http://forums.rockbox.org/index.php?topic=7605.0

This is in the Hardware forum of the Rockbox forum.

This involves connecting a RTC chip (5 leads) to five points on the H120/H140 mainboard and patching Rockbox to support the chip.  The patch adds a digital time display to Rockbox and provides date-time support to the file system.  Recorded files are named with the date and time.  The mod takes about one to two hours depending upon your soldering skills with small components.

The BIG result here is recordings named with the date and time in the filename.

_and_ you will need to compile your own rockbox version to enable the clock chip use...

Yeah, I have the Maxim chip, but I read through the guide on compiling and I'm lost. Can someone help me get Mmmm's latest version of Rockbox compiled with the RTC patch? I really like the idea of having a real time clock on my iHP-120. If I can get the software patched, I will be able to work on wiring the chip in this weekend.

Well, I just installed the RTC chip following the great instructions by jmdearras:

I just need help getting the REP version of Rockbox patched with the RTC code.

You'll either need the dev toolchain or be nice to Mmmm in the RB forum and maybe he compiles you a version....
More info on compiling your own RB is on www.rockbox.org - check the wiki

Thanks, I got it done.

The iRivier H320/340 has a real time clock, correct?

So does it have the digital clock display and date/time
information in the file system using the standard Rockbox
release?  Or does the H320 also need the specially
modified Rockbox load?

Thanks.

After soldering in the RTC chip (Maxim DS3231s) and getting the software patched, my iHP-120 can show an analog or digital clock (via the plugin Clock). It also date and time stamps files, which is what appealed to me. I don't have a 300 series, so I can't comment on it.

H3x0 have an RTC chip which (official) RockBox uses: time is shown on the status bar, the filesystem uses the date and time, and when recording, date and time are in the filename. I figure this last feature is _the_ reason some people do  the H1x0 RTC modification

Yeah, forgot to mention that the current time is displayed on the record screen on the RTC modded iHP-120.

Good news. The Real Time Clock patch is being incorporated into the regular Rockbox builds now.

That's great news!  I'm getting the RTC chip installed on one of my units and I was a little worried about getting the patch installed correctly into a build.

I just bought a couple RTCs.  I don't know when I'll get around to putting them in yet, but it's nice to see the mod being incorporated to the builds.

The patch is in the current svn but is disabled, you need to build your own and just change one file: firmware\export\config-h120.h

look for the line that says

/* Set to 1 if you want to build with RTC support */

and change the line below it to

#if 1

and rebuild.

EDIT: there's a discussion going on about offering a separate H1x0 build on the official rockbox site... keep your eyes open

The current RTC patch has auto detect, why disable it in the build? I don't know how to compile and don't have any interest in learning how to do it. WTF?
