7-segment lcd display

Nu Audio Science · 1 Oct 2005

How cool is that 😮

oddson · 2 Oct 2005

I love the background 'trace' of the segments. Makes the display pop off the screen. Very cool 😮

The use of the selector to turn off and on segments is brilliant.

(The 'nothing' connector had me confused. I think leaving it out would be clearer.)

BTW - the top segments are clipping slightly when I load this up - though they look OK in your screen shot.

rl · 2 Oct 2005

the "nothing" connector is just an empty V-connector and is necessary since the selector creates and holds empty slots only when something is connected.

clipping: I have noted that too. In default zoom mode it works ok. In other resolutions SM seems to clip the png-image while scaling. Maybe a bug. As a workaround the images should provide some more "headroom"

Hi Rudolf,

thanx a lot, that looks really cool.

Best wishes, FRitz

Right. I didn't think that one through.

You can disconnect an input on a selector and it won't collapse as long as the last input is still in place. But you'd still need to do something like this for that one (number 9) on two of the segements anyway. Thinking it through now the 'nothing' connector makes perfect sense.

It looks like the clipping is from the bitmap being anti-aliased and the grey pixels are getting clipped. I couldn't figure out how to add the headroom needed without messing it up. 😕

great stuff rl ... i love 7 segment stuff 🙂

Dj-Grobe · 14 Oct 2006

How can put the numbers in white?

oddson · 14 Oct 2006

As the whole thing was done with bitmaps you would have to generate all the pieces in the colours you want.

A suppose the colour matrix component might be able to do this instead but my guess is it would be more work than just recreating the bitmaps in a graphics program.

Duncan · 14 Oct 2006

nice solution

Dj-Grobe · 14 Oct 2006

My knowledge its not good yet with sinthmaker..... i learn lot of things but other no yet.

I try check where this schematic load the bitmap, but not understand how load the bitmap.

If somebody can indciate or help a little, i apreciate.

oddson · 14 Oct 2006

There are eight bitmaps. The backgroud with the segment trace on it and each of the seven segments.

rl has it so you click on the viewer for each bitmap.

For the background, click on the background picture one level deep.

For each segment go into the s1, s2, etc. and click on the segment in each.

Dj-Grobe · 15 Oct 2006

for the background its ok, but for the segmets, i go to s1, then deppe adn deep and deep and no see wher he call the bitmap ; (

Dj-Grobe · 15 Oct 2006

finally understand how work, create new graphics for this take work, need some icon editor or something like that. Its possible extract the bitmaps of this osm for rework?

Its possible ? how?

Dj-Grobe · 15 Oct 2006

Change colors using color matrix, can be gret feature for have this LCd displan in any color : )

oddson · 15 Oct 2006

Here's a simpler version with bitmaps for entire digits.

lcd-display.osm

I don't think it adds much overhead and it's easier (for me at least) to manage the bitmap files.

Here's the PhotoShop file I used.

LCD-digits.psd

I've added a color matrix shifter that allows you to change colours for the segments but not the background. I don't understand the matrix well enough to use it for anything fancier than changeing the hue/intensity.

Dj-Grobe · 16 Oct 2006

very very nice work 🙂

awesome and nice lcd now 🙂 (the original its great too, but now look super nice) thanks os much oddson this tweak.... its wonderfull 🙂

I start thinking in create some public ftp for save all this osm, and make database osm I see lot of dead links to osm, in the forums, some sugestion? think can be util add osm storage site for make some database of osm s for all Sm comunity?

: )

Why not just add them to the User Creations Area of the wiki? 🙂

Dj-Grobe · 16 Oct 2006

I not cheked that secion on wiwki, i check soon 🙂

WIKI? What's that? 😉

Despite all the work on it, and my honourary designation, I still don't think of the WIKI as the place for examples.

Maybe I'll go through my web-files and pull out some examples.

I think it's quite a decent place for putting up stuff with a description and get it hosted on our servers. It's not ideal, ideal would be something that would be simpler to use for the one uploading stuff and with ratings and whatnots. But until we have something else I think it's decent. Maybe there already is some php solution for these things that one could just install on the server and customize to fit with synthmaker.com. I really haven't looked into it yet but now you've gotten me interested 🙂

Dj-Grobe · 16 Oct 2006

Oddson in trhe osm examle, the numbers are inverted, chek that 🙂

If you send number 150 , the display show, 051

: )

Its just inverted position of number sgments 🙂

oddson · 17 Oct 2006

Opps... 😊 I had it right and then made the display smaller. Must have shuffled them up when I did.

rlahalla · 17 Oct 2006

@ stefan - if you want try joomla, install FacileForms,VFM file manager, and jocomments system components (IMO). It allows you to setup up a file manager with comment and rating system, a zip utility for downloads, and the ability to create and customize an upload form for users so that the uploads get delivered directly to the downloads bin.

I'm also pretty sure that they have a module that allows phpbb integration so users from this forum could access content only, y'know. Just a thought 🙂

This is so off-topic, but anyway 🙂

Joomla does indeed seem interesting, especially if one can integrate it with the current community thingies we already got up and running. Will have a really good look at it. Browsed around for "ready-to-use" solutions a fair bit yesterday, and article publishing and reviewing scripts were the closest I could get, but it wasn't close enough imho, and I got a feeling that it'd be much better to make something more... homebrewn instead. Thanks for all the tips, will have a look at it all during the day.

Cheers!

oddson · 18 Oct 2006

Even though no one asked for it, here's a version that uses only drawn elements and includes a decimal. It's resizable and can easily take more digits (but doesn't display negative numbers). There are properties for the segment length-to-width ratio, segment on, off and background colours.

drawnLCD.osm

(It fills the digits left-to-right, which is a bit off. A better parser method could easily be implemented.)

rlahalla · 18 Oct 2006

@ stefan, if you ever need some help with joomla, I'd be more than happy to help out if u ever need it. I've done a ton of work with joomla, so I just thought I'd offer 😀

sorry for hijacking the thread!

TheAudiophileDutchman · 18 Oct 2006

@oddson: greatest LCD display yet! 😍

@rlahalla: I've selected Joomla a few weeks ago (hoping that this is the ultimate Content Management System around) and just downloaded Joomla 1.5, so I just might have a question or two too (Tutu) 😉

AngularMomentum · 18 Oct 2006

Hey Joomla 1.5 is out?! Going to fudge around with that today!

Oddson, looks great! 😍

Beta version. Started playing with it yesterday. Seems really cool!

Love the LCD's too btw!

edit: seriously, we can talk about joomla in the off topic section. a whole bunch of us obviously uses it (sk0re too!), so start up a thread if needed 🙂

rlahalla · 18 Oct 2006

Ok, joomla has been discussed (oops!) but as for this LCD display - oddson, this thing looks great! 😀

BasherT · 31 Oct 2006

The LCD display is great but as a newbie I am having trouble getting it to show up on the front panel. I have the LCD within a module but it just isn't showing up. Any ideas?

I am probably doing something stupidly wrong but all help would be appreciated.

EDIT: I was doing something stupidly wrong. I hadn't included a wireless view input inside the module. **blushes** I have the display working beautifully now. Thanks for posting it.
