Custom Character Generator

[Darrel Taylor]

Yikes!, I'm falling behind here. Not enough hours in a day.

Sean, Ralph and Art,

Thank you!

This was actually a side product of what I was working on, (more on that later). But it worked so good I thought I'd Post it. Could use a little more speed. And then there's that "FireFox problem'....uuugh. Fortunately, the main project is working much better,(more on that later). Is there an echo in here?? Hmmm.

Luciano:
Thanks for that, well not really. I've actually used that program before(back when I was using "Stamps", yuck!). So i guess you could say that the thought wasn't very original. However, the LCDCC.EXE program isn't very PicBasic Pro freindly.   While it does a good job of creating data for the characters, it doesn't address how to send them to the LCD, or what address you need to send them to.

I think this version overcomes those deficiencies and allows you to just Cut&Paste the results into your "PicBasic Pro" program.

But then, it doesn't answer Dave's request.  Kinda screws up my defensive posturing,...(more on that later)...there it is again, who said that?

Dave:
It's written in Javascript for browsers. I don't know if it can be turned into a stand alone program or not. ???

However, if you don't want to enter the forum to use it. You can bookmark this page, and use it anytime you like.

Or, go to that page and use (File | Save As) and you'll have an OFF-line copy.

Hi Darrel,

My computers were manufactured in the last century.

Below you can find the performances of your javascript on my machines.

During the test I have generated only one character. (Letter T).
I have no Antivirus installed on the computers.
Only IE6.0 is open. In the W2K task manager, IEXPLORE.EXE gets
98% of the CPU when the javascript is executed and goes back
to 0% when the javascript is over.

===============================================

Generated character: (Letter T)
LCDOUT 254,64,31,4,4,4,4,4,4,0 ' Cust Char #0

Results:

(I click the eleven boxes with the mouse and wait).

Pentium 166 MHz, 128MB, W98SE, IE6.0:
105 seconds

Pentium II 300 MHz, 256MB, W2K SP4, IE6.0:
27 seconds

===============================================

I like and appreciate your support in this forum.
This is only a problem report.

Best regards,


Luciano

That's good to know, thanks Luciano.

I knew it was a little sluggish, but it didn't seem that bad on my 3ghz, Hyperthreading laptop.

I'll have to see what I can do.

Hi, Darrel

The best you could do is a Downloadable version ...

That would definately be the fastest way, but by now, most people have learned not to just download executable code written by a nobody. Many of them/us, found out the hard way. Even if they're not an intentionaly malicious program, inexperienced programmers can cause just as many problems, if not more. So, from everyone else's perspective, I would NOT download an executable file from Darrel Taylor.

At least with Javascript, you don't have to worry about that (As long as you have your browser security set somewhere above "low"). And, hopefully, it will give easy access to more people.

I now know why this program is moving so slow. And because of the same reason it's getting slower with every additional post in this thread.

I'm sure I can make it quite a bit zippier.   Just a matter of getting it done. Although I don't know if it will ever be sufficient at 166mhz.

I sure hope you aren't using it with Win2000 or XP

My slowest machine is a 350Mhz AMD K2 with about 512 Megs of RAM onboard. It has Win2000 on it, and I barely find it tolerable for web surfing (plus it takes forever to fully boot-up, and this is a fresh install). In fact to tell you the truth, I rarely ever use it, and instead use my 2 Ghz Pentium 4 machine.

If I didn't have a faster machine already, I would probably look into buying either a new motherboard for the AMD box, or just buy a new Wintergreen (or similar) unit if I was on a tight budget. It is sad that computers go obsolete so fast, which I think is largely brought on by bloated operating systems. Heck even Linux which was once heralded as being so much faster then Windows, now also requires a pretty healthy machine if you want to run it with a full graphical interface, and the newest apps.

Back to the LCD character generator:

Would using some other web friendly language help improve the speed?

[Darrel Taylor]

OK, well it took almost a complete re-write, but I think it did the trick.

And, it works with FireFox now too.

It's almost instantaneous on my machine (3ghz), but I guess that doesn't mean much.
I don't have any slow computers to try it on.

Luciano, can you give me another Speed Test??
