  1. DesignLab 1.0.4 Released!

    *Thumbs up !*
  2. Working on DesignLab 1.0.3 release.

    So, that's the 3 Mbit you where refering to, now I understand ! 3 MBit would not be enough, but 6 Mbit/sec would be enough to control 8 panels at 24-bit color / 25 fps. (even with 75% load on the USB) I'm learning every day :-) thanks, Kris
  3. Working on DesignLab 1.0.3 release.

    3 Teensys :-) Still need to connect the 6th panel to every teensy, making it 192x96 pixels. (there was a problem with one panel, had to ask for a replacement) 75% will be enough. When I do my calculation, in theory I could hookup 40 teensy, but I will only need 10 of them. (so, about 25% is enough) Hmm, sorry to hear that Papilio only does have FTDI (115K is definitely not enough "speed"). But I think I go with an ENCJ28J60 or something. Should be possible to get something working over a network connection fast enough :-)
  4. Working on DesignLab 1.0.3 release.

    Just as a side-note to my question of the band-width of USB1.1 devices on a USB2.0 bus/hub, I can answer myself :-) You can connect as many USB1.1 devices that consume 12mBit per device, to fill up the total USB2.0 bandwith of 480mBit. When I connect one USB1.1 device and send a block of data to it, takes exactly the same amount of time as sending different blocks (with the same size) to different USB1.1 devices in parallel. (multiple simultaneous threads in my dotNET application) So, I currently have 18 (only 15 connected in the movies in the article on my site ) RGB panels, running a live-feed from my macbook Pro :-) (I can even output the videostream from my webcam to the large 160x96 RGB LED panel) Still 42 panels short to finish my project :-) (320x196 pixels)
  5. Working on DesignLab 1.0.3 release.

    3mbit trough serial port ? Thats weird, where is that comming from ? That will only give about 21 fps for 6 panels. USB1.1 is 12mbit (teensy can do 12mbit) en USB2.0 is 480 mbit. (USB1.0 is only 1.5mbit) One question that I still need to investigate, if you connect multiple 1.1 devices to a 2.0 host, Would the total speed of all connected devices be 12 mbit, or could i use the 480 mbit divided over 40 1.1 devices ? Maybe i should read a bit more about usb protocols and standards ...

    Hi Alvie :-) I'm also using panels with HUB75 interface. 32x32 pixels per panel. I now have 18 of these panels, but I'm only using 15 of them, in a 5x3 configuration. (so 160x96 pixels) Next month is my birthday, my wife is going to order another 18 of these panels. After that, I will buy another 6 panels each month, until I have 60 of them. (ooh well, this will be the "eye-catcher" at our next Christmas event, so I still have some time left :-) I'm playing my animations from SD cards. (yup, multiple cards, because I can't get the read-speed above 2 Mbyte/sec, it's just a proof of concept, maybe I will interface with a SATA or IDE drive later on) Currently also using a Teensy 3.1+ for every 6 panels. I hope to soon port the whole thing over to Papilio, maybe I can do more panels with one Papilio ? I assume the RGB LED panel wing for the Papilio, is designed for these HUB75 panels ? Today I connected the whole thing to my macbook, currently writing some stuff to get the videostream of my internal webcam onto the LED matrix :-) Ooh well, any capture device would work, so a video2usb device would give me the possibility to watch live TV on this matrix, maybe I switch this "processing-thingy" to a RaspBerry Pi, or I start using my Atlys FPGA board :-)

    A big "THANK YOU" to Alvie & Jack for their continued efforts they put in this ! I got the VGA sample "up and running" (jippie), so I can now start designing an interface to control my large LED RGB LED matrix. (which is already grown to 160x96 pixels (I got 24bit colors instead of 16bit, 24 fps, 120 Hz refresh for the moment), and will continue "growing" till I have 320x192 pixels) Time to buy a few more Papilio boards :-) best regards from Belgium, Kris

    Hi Jack, Any news on the vga examples yet ? Thanks, Kris
  9. Working on DesignLab 1.0.3 release.

    Hi Jack, indeed, the one with the HDMI class :-) I know I can't the HQVGA & VGA together, was just refering to the fact that HQVGA was the one that was working in the past and still is working, so my hardware seems OK, because that one initially also syncs at 800x600 ... So, to be clear: - VGA_640_480 is not working for me (this is the one with the HDMI class) - VGA_ZXSpectrum is also not working for me (but I don't need this actually) don't worry about the short replies, I know how it's like to answer messages on a phone, LOL :-) don't rush, I can wait, still need to take my rest aan keep my pace slow ... have a nice weekend, Kris
  10. Working on DesignLab 1.0.3 release.

    Hi Jack, I forgot to mention, I already moved the files to the correct location. (examples) So this is not the cause of my problem :-( Nothing appears on my monitor, but is seems to be syncing to 800x600 - 72 Hz ... (otherwise, when a sample does not work, it switches back to the HDMI input of my intel NUC) In the meanwhile I also tested it with a 7" TFT with VGA connection (800x480) I still had laying around ... Same result. I know it's a beta, no problem on beeing a beta-tester ... I just need some guidance here :-)
  11. Working on DesignLab 1.0.3 release.

    Hi Jack, Hi Alvie, Is there something special that needs to be done, to get VGA up and running ? (I want to use the VGA output on the Arcade Megawing) I uploaded the Megawing circuit to my Papilio Pro, and was able to run the VGA wing examples (HQVGA that is). I changed the define circuit for the megawing in to VGA640x480 example, but if I look at the serial output, I see "Device not found". Also, when I try to run the VGA_ZXSpectrum, I don't see anything on my monitor. Did I overlook some coding/settings, or do I need to try out another (older) monitor ? (all my monitors are 1920x1080 FullHD Philips Ambilight Monitors) thanks, Kris
  12. Working on DesignLab 1.0.3 release.

    Indeed a Teensy (sorry to disappoint you, lol) I had this thing laying around for to long ... Now that DesignLab 1.0.3 is out, I will start porting this thingy to Papilio Pro (can't be that hard), I'm sure the Papilio is a better candidate to drive these RGB panels. (I'm sure the Papilio can keep up the "pace" better with the SPI / SD card then the Teensy does) Also, when Alvie does his "magic" for the RGB LED panel wing and some examples come available, I'm sure we will get better performance :-) (24bit, 120 Hz refreshrate, 25 fps is still my goal) I'm off now, to excited about the new Designlab, time to play :-)
  13. Working on DesignLab 1.0.3 release.

    Sounds awefull :-) Looking forward to it ! In the meanwhile I'm home again :-) (still need to take a lot of rest and keep everything at a slow pace) Ooh well, I missed my electronics/programming addiction so hard, I started coding right away for my RGB LED matrix. (6 panels, good for 96x64 pixels - measuring almost 60 x 40 cm) I wrote a converter that converts video files to raw-data files. I put these raw files on an SD card, and "play" this data to the RGB panels via Arduino code (SmartMatrix library) The result is 20 fps, 100 Hz refresh rate, 16-bit coloring ... The framerate is less then 1 percent off. (original Teletubbie video is 2m33s, mine is 2m31s while playing, will fix this when I got my extra panels, need to do some extra syncing after all while parallel processing data) It's "hard" to captures this on video. In real-life the video is "flicker-free" and the colors are more "brilliant" ... I think I need to find a tutorial on "capturing" this "thingy" on video in a beter quality. (for now, you just have to believe me that the quality in real life is better, LOL) Teletubbies: Wipe-out (just to show that speed/fps is OK): My wife ordered another 6 of these panels as a Valentines' present, they should arrive on monday or tuesday. My panel will be 128x96 pixels after that upgrade. My birthday is also "upcomming" in april, she will buy me another 12 of these panels ! Eventually, I want this display to be 1m80 x 1m (almost 16:9 resolution with 288 x 162 pixels) I hope I can keep the data-flow high enough :-) (I will need to implement some sort of compression, because my SD card / SPI interface will not be able to keep up the pace) Next week, I will do "nothing", just keep some rest. After that, I hope I can start drawing again in Solidworks. Still need to make a slight adjustment on the Papilio Pro case, and do some work on the Arcade MegaWing casing, and do some "design" for my German friend, Felix :-) best regards, Kris (happy to be home again - now looking forward to DesignLab 1.0.3)

    You guys never give up :-) I love it ! Where is that "I like" button like on facebook ?
  15. Hi Jack, Thanks for the update, indeed some good news :-) (I, on the other hand, need to stay in hospital for at least another week - I want to go home, so many things waiting for me to do at home) OOh well, maybe if you release a new Designlab version within the upcomming week, I can start impressing the nurses :-) (got my Papilio Pro hooked up to the television over here) best regards, Kris
