Guide DigiMeter - LED System Activity Bar-Graph/Chaser - SOFTWARE v1.7

I have the same problem. I’m running xp pro.

Great guide by the way!!!

 

At what stage do you get that error?

 

well i get the "DigiMeter has encountered a problem and needs to close. We are sorry for the inconvenience." message when i try to run the v1.7 and on the othre 1 i get "Data source is either invalid or cannot be found. System message: a required argument is either missing or incorrect" when i run it????

 

That doesn't really make sense, that's Windows for you though I suppose, give me a few days and I'll see what i can do.

 

That's exactly what's happening to me, thanks for the guide, and hopefully once the software's sorted it should be class.

 

wow, nice guide, I've been hoarding blue LED's with plans to have a graphic equaliser type thing in the front of my case using a kit from maplin connected to an audio output. But this looks to be a much more useful, can't wait for a version with more LED's.
(ps, stupid newb question, if a parallel port has 25 pins, why are you limited to 8 led's, is it that only 8 pins are used for signal and the rest are power or whatever?)

 

The port has 8 data lines, designed for transmitting one byte of data at a time. 8 of the pins are just ground and some are inputs, however, there are 4 additional "status register" output lines, but they are more complex to access, but 12 LEDs with no additional complex circutry is in theory possible and i'll start codign the software to access them after i've got these problems with some XP machines sorted out.

 

one little warning again, i am sure i've posted this before somewhere on the electronics forum, but be very careful.

some old motherboards, especually the old ones with overdrive sockets can't source/sink more than 2.4ma.

a hex buffer would be a simple 40pence solution, that would seriously reduce the risk, and allow more current with safety.

 

True but with your average LED you're only looking at a ~1.3mA current here.

 

ok thanks!!!

 

Strangely enough it seems to work now. This is version 1.6.0.1.

Seems like a tidy bit of software, now i have to find me a parallel connector so i can try it... Cheers!

 

Yeah the old software works now but not the new.

Has any one got a screen shot of the new version???

 

Looks exactly the same, just with a few more items on the list and more in the options menu.

 

ok!
well will u be able to sort the new vertion for xp plz???

 

Having a problem when running. XP Pro tells me it's the sysmon.ocx file. Can give a screenshot if needed.

 

sorry for my stupid question but i dont know english very well so its a bit difficult to understand that sheme.Here is the question: i have to connect led's positive(+) to port pin (2...8) or negative(-)?

 

it doesn't matter!!!

 

Yes it does!


You need to connect the LED's Annode (+) to pin 2 - 9. If it isn't the correct way round the LED wont light.

 

oh yeah my bad!! diode!!! lol

 

ok is there a new link to download the newest version of this software, and also could someone post a open souce version of talking with the paralell port this way in VB please, it would be greatly appricated - i'll just write some lighted fun software for it
