Tired of not having a clock in my car I have hacked together a clock visualization that works with the v1.02 player.

I based my code on the overlay kernel patch that Kim Salo wrote. Instead of scaling the 32 line display down to 24 lines, I simply block off a region of the display, but only if nothing is currently writing to that area of thie display.

The end result is I now have a clock in the lower left corner of the display when I am in the "Track" information display. If I hit pause or do anything to write to that region the clock disappears.

I took a photo with my digital camera, although it came out blury. If anyone is interested in me creating an easy to use package let me know.

Installation requires both a kernel hack and a usermode daemon that must run before the player.

Cheers.

One more time with the attachment ;-)

Cool, I would love to have this as I don't have a clock in my dash after I removed the original player.

Could you post have to do it, please ???

v1.1 has a clock as one of the time display modes. It also has a full screen clock visual.

Error: File is not a GIF: header is 'دØ', not 'GIF'

Is this a JPG you got the wrong file extension on?

Well, will not nag you when 1.1 is here, but does the clock visuals apply to MK1 too.
(Does it set the clock from a RDS channel, then present it in any visual one would want?)

TommyE

I'd definitely be interested in this. It's annoying having to answer the "You paid 1200$ for this thing and it doesn't even have a CLOCK?!?!" question so many times.

I know 1.1 will have a clock, but I don't expect to see 1.1 for at least a few more months, so in the interim it would be nice to have this hack.

(O|||||O)

But it does have a clock you just can't see it

Well, let us have it then!

that's the big question, I want the clock visuals in the MK1 version too,
to set the clock via GPS.

Do you have the files somewhere for download to get this working? If not, I can host them off a directory on the logo site, as this is something I am sure a few people are willing to hack into their empegs without an easy to install package (like myself, who still months after getting the empeg stares at the dash looking for a clock.)

There he goes promissing us the world again:)

...proud to have owned an Empeg since 00287

I zipped up the kernel diff, a binary kernel, the usermode daemon, and screenshot and some brieft instructions.

Patch kernel, run usermode timed before running the player and you are good to go.

These attachments on the BBS don't like me. Use this URL.

It's just not as easily accessable as having it right on the info screen, which since there's already a clock in most cars elsewhere, why need it in front all the time.

I'm like one of these total linux morons. I know nothing :) Could someone let me know how to recomplie the kernel and apply the patch, step by step if that is possible.

Thanks :P

I provided a binary kernel and binary daemon so you don't have to compile anything. Consult the FAQ here
on how to send the kernel to the flash of your empeg.

-Kit

Maybe I'm just an idiot, but this is what is happening.

When following the instructions in the faq, I get this

H:\empeg>download zimage-1.02 10000
Turn on empeg unit now
Strange, we got a zero byte read.
**** REPEATED UNTIL EMPEG IS PLUGGED IN ****
found empeg unit: entering program mode
Strange, we got a zero byte read.
Couldn't find manufacturer ID!

H:\empeg>

And it cuts out
or it gives me this

Error status in readbyte 16
Strange, we got a zero byte read.
found empeg unit: entering program mode
Strange, we got a zero byte read.
Couldn't find manufacturer ID!

H:\empeg>

Both times I just plug in the empeg and that's what it does. Is this a known issue? I'm using the correct com port version of download.exe.

Thanks

Also, I just attempted to use Tony's upload tool (which appears to be similar to the download tool. Different name tho, and it says everything is transferred fine, but the system does not load.

This is the results I get on COM2 durring boot up.

What all did you compile into the kernel? Just the overlay patch, or also the displayserver and volume adjustment patches as well?

In attempting this I did not overlay anything. This is upgrading from a totally fresh kernel to the kernel to get the time hack.

I was asking Kit about the kernel to see if I need to recompile mine to keep all my other goodies on my empeg. With your particular problem, I'm not sure what happened. Does reapplying the normal empeg upgrade file resolve the problem?

Oops, *feels like an idiot*. Yeah a upgrade to the dev kernel fixes the issue.

You are geniuses!
It works very well!
And I even have the sourcecode to make my own own
overlayed tools.
Good work!

But... Any good ideas for how to set the clock?

Yours

Jan Marius Evang (Escort Cab + Mark II)

Um, from the empeg player menu!! - "Settings ->Clock"

(list 6284, Mk1 S/N 00299 4GB blue [for sale]. Mk2 S/N 080000094 6GB blue)

Hehe, very funny!

mk2 rev.7 Trillian # 080000263 6Gb blue/red

Thanks :-)
I looked through all the installed files and all the emplode
options :-) (Why is there such a setting? What does it *do?)

But... With the time set to 14:47 (local time), the timed shows 12:47 pm... even after a reboot.

Marius (Escort Cab + Mark II)

Your TZ is set bogusly. Somehow, set TZ to GMT, and it should sort its life out. And yes, I do mean GMT -- even if you're not on that meridien. Or possibly, I mean UTC. I can't recall what Unix calls it.


Roger - not necessarily speaking for empeg

Edited by Roger on 31/05/01 02:30 PM.

Hehe. I think I'll choose the "easy" way.
Set the empeg time to two hours "wrong"

I guess this won't hurt anybody?

When I get a cross-compiler running, I'll replace the clock with a 24h clock, I think.

Marius (Escort Cab + Mark II)

UTC is the more recently-standardised name for what the rest of the real world calls GMT . Both are accepted so long as they exist in your TZ list.

Don't ask me where to find that in Linux; it is usually associated with global locale data somewhere, so maybe in /etc.
