ICE Tube Clock Firmware Comparison

[bastard]

Hi,

as I'm not sure which firmware I want to use or modify I've done a comparison between them. I hope I got all features. If not, please give me some input - I'll put it in asap.

The firmware can be downloaded here: Adafriut / caitsith2 / jsgf / DigiSage

stefan, thank you so much for this - very helpful! we've made this a sticky and we also made this a blog post on adafruit, thanks again!

Fantastic, thanks a lot for doing this! It really helps to be able to see them side-by-side.

And you scooped me on drift correction! I only *just* committed that, and haven't announced it at all yet!

One thing I'd mention - and admittedly because I'm biased from having spent some time implementing it - is display transitions. Aside from looking pretty, I find they do actually help give a cue as to what just happened when you pressed the button without having to read the display... And if the shape of '9' is worth mentioning, then this is

Maybe its worth having a "notes" or "other" field for things like that.

It's a bit difficult for me, not to misunderstand you. I'm not sooo good in english ...

Sorry ... I just downloaded the last firmware paket from git ... and it was already in, so why not mention it.

I agree, but do not fully understand. So I make you a "notes" field. What would you have to be in there? Please give me your words.

OK, rather than having separate lines for relatively minor things like "shape of 9" and "test mode", add a notes field with:

Caitsith2: (#) Adjustable shape of 9. (#/tick) Test mode.
Jsgf: animated display transitions

Though "shape of 9" is so simple to implement I may as well do it...

I have no trouble building / flashing my firmware with the MacOS X avr packages. However, there are definitely things I can do to make the file smaller. Also, I believe I discovered a bug in the "No" seconds display mode, which hopefully I will fix soon.

Hi,

I just installed all the needed pakets on my debian lenny server - it also isn't able to upload the .hex file, sorry.

Sorry, I've no Mac around me.

Hi,

I believe gcc 4.3.2 ( WinAVR 20090313) has more aggressive function inlining optimisations.
Adding "--param inline-call-cost=2" to the compiler options reduces the size of DigiSage firmware as follows --

From:
Program: 16648 bytes (101.6% Full)

To:
Program: 15488 bytes (94.5% Full)

Hope this helps someone out.

yes! It worked! Updating the sheet ...

Thanks for the tip! That reduces my code size from 9516 to 8642 which is a nice saving!

FYI, I posted a new build of my firmware, just bugfixes at this point, but I thought I'd mention it here.

Might I suggest posting URLs to the project homepages in the chart?
Would simply finding this stuff for newbies...

I'm not sure if the board software allows this, but I'd prefer an HTML table over an embedded image if possible. That way you can add things like links to the forum topics or web sites, be able to copy/paste information, etc.

unfortunately html-tables are not possible in this forum. If they were, I would have done it that way. I added the URLs beneath the table for easy clicking.

For those of you, who haven't yet noticed: jsgf left a little easter egg in his firmware: just look at today's date . . .
