Fiddled with the webcam, got a better pic These displays update so fast, much better than my graphic LCDs!
How would these things deal with a power switch? Im building a external box for them, and would like to know if im gonna fry them from the sudden surge from the switch or something before i try it
WAY fast update... It works with .9.3... You want it, and it's not on the site??? howabout Here Thanx RamZ for getting it to me REALLY quick... btw... anyone has problems with me hosting it, let me know... I don't wanna step on any toes, and this is a buggy alpha version... Scrolling doesn't work etc... But it looks nice mostly... I used exactly linear's wiring if any of you needed to know...
Right then, thats that done. /me pulls out the microcontrollers and starts trying to interface it. As I posted in the other thread, a good skin and config here.
I just wired my display and made some code to show text and bitmaps on the VFD. Writing one full screen bitmap takes less than 10 ms so there should be pretty good chance for some animation. Anyone want to make some animation and I can build a little prog to show that ? The frames should be in separate 128x64 1-bit BMP's and named something like frame1.bmp, frame2.bmp... Something I noticed is that if I set the brightness of the display to something else than 100 or 6% I get a high pitched whine. At about 50% it's loudest. Is this normal or should I look for some loose components/something else on my PCB ?
Kinda normal, But not really... On mine it was unnoticable (Then again it was on top of my Peecee which is at something like 99dB... (Pretty loud with the orbs...gotta get those changed.) Yes, vfd's make a little noise... not distracting though, maybe check connections, but more likely just the display characteristics.
I'm makin up a little animation, will update this post as I make them I'll make some more complex ones if someone tells me what they want ::EDIT:: click to DL .zip file containing frames
Thanks for the animation Morphine. You can get the animation util here: http://www.skippari.net/phpBB2/viewtopic.php?t=121 I'd like to know if it works for you and also if it doesn't.
Tried the Ani... Works great... I ran into a problem when I changed the parameters in the ani.txt with edit from the command line, but when I changed it in notepad, I had no problems... Must be an extra space, or CRLF that did it.
Although I have not yet recieved my display I have started programming it and created a small test program. If it works (and i have the nasty feeling it won't) it should display the letter A in the upper left and one on the 2nd row 2nd column.. I know it's not fancy but just wanted to know if my code works.. if it works let me know i'll give you something cooler.. it should be compatible with the liquidmp3 wireing.. Testapp.zip
No A I get a solid fat line across the top left corner of my display followed by a thin line under it.
Actually i'm amazed it displayed anything..programming without a display kinda feels like a blindman making a painting.. I updated to program to display a bunch of A's instead of 2... might work now.. then again.. i have no idea about whats going wrong here
yarvieh, welcome to the boards, dude. Much respect. Since you didn't introduce yourself, let me do it: yarvieh is the author of LCDStudio. Glad to have you with us.
I tested both testapp versions and for me they cleared part of the bottom row (8 pixels high) when I had left some previous image on the vfd. I didn't notice anything else happening. Should the code clear the display and which layers are enabled ?
hey guys, i posted a summary of some of the info minus the detailed datasheets over on my page... http://flecom.net/[H]OCP/vfd.html also whipped up a little schematic for the wiring i (and some other people?) are using over here if you guys are going to do a write up on the site - feel free to use it working with Yarviech to get a LCDStudio plugin up and running so we can get something besides winamp on these absolutely beautiful displays!
I just wrote a Blinkenlights movie player for the display. You can find it here: http://www.skippari.net/phpBB2/viewtopic.php?t=124
Different to the MarkusZehnder plugin wiring, that's right. And nice to see you, welcome to the boards.
