LOL This is WONDERFUL -- thank you so much -- I am snowed under with work at the moment -- fighting my way toward the weekend -- but I cannot wait to root through all of this and see what you did.

Also, I hjave to say that this ha sinspired me to "pull my finger out" and actually start constructing the display so I can start playing with these effects on the real display.

FYI Keep your eyes open for a follow-up blog later today on MUC Designline in which I will be pondering whether to use I2C or create a custom interface to link two MCUs (as part of my BADASS Display, of course)

@JeffL: ...Anyway I feel just TERRIBLE about the distress that I may have caused some of you...

No worries on my part -- I hadn't got around to doing anything yet (struggling to keep my nose above the waterline) -- thanks for alerting us to the problem.

Pixel Fader Simulation

Hi, here is link to some stuff I put together for fun illustrating fading pixels on and off and abstracting from the hardware.  It turned out to be very flexible.  The first thing I did was just select pixels at random and give them a random rgb color.  If the same pixel was randomly selected later and given a new color, it would fade from the one color to the other.  Then I changed it to draw light the pixels as a vertical bar from the bottom to the selected pixel and fade the bar out over time.  Then I added some gravity effects so that the bar would fade out from the top down.  Then I decided to stop playing and go to bed...

Warning, Conduit adware alert!!

Max,

I just noticed something kind of horrifying. After I installed the program I linked you (which is everything I said it was), I tried doing a Google search and discovered that the "Conduit" search engine hijacker had been installed on my machine (even though I had in fact agreed to NOTHING other than the download itself)! Now "Conduit" itself is sort of nasty but it is after all just a kind of adware, so I did a search on the removal process and was able to get rid of it in a few short steps, and the instructions that I found online (the ones that invoke adwcleaner) worked rather well and I believe they removed the problem completely. What I wanted to say first is that this download site is owned by Cnet which I understand is itself owned by the CBS network, and it is the very height of corporate irresponsibility AND GREED that they feel they can maintain this site as a paid mechanism for infecting other PCs with unwelcome adware as a means of monetizing the website, and I think a wholesale boycott of CBS products would not be out of the question. It's probably also possible to download the program directly fron the developer's website, I haven't looked for it yet but if I find it I'll leave that as the download link. Anyway I feel just TERRIBLE about the distress that I may have caused some of you, and I wanted to get this warning out as soon as possible, thanks to all of you for your patience and understanding!

@djohns: Maybe I'll write a little program that does a simulation on a PC and send you the source.

I hate to eat into your time like that (I know how precious time is), but I would love to see that program LOL

Haha. Let's see if I had the pointer to your house I could access it...

Really, though, this is a fun concept. Maybe I'll write a little program that does a simulation on a PC and send you the source.

@Dyson: I thought I would just chip in with my hardware oriented thoughts.

Chip away old friend LOL. I know what you mean -- the only way I can wrap my brain around any of this stuff is to have a good visualization as to what's actually happening in the underlying hardware.

@djohns: ... Now, call set targetValue for each pixel based on your wave form, then loop through the array, call Animate() and DrawPixel().  Finally, call ShowDisplay() to blast it to the display.

It all sounds so easy when you say it quickly ... when can you come round to my house to get this working in the real world LOL

@JeffL: Here's a link to a fairly small "freebie" analyzer program that has a 1/3-octave mode that you can install on your PC and have a look to get some ideas...

Wonderful -- thanks for sharing this
