Howard1 Posted September 2, 2014 Report Share Posted September 2, 2014 I am very interested in using the Papilio to drive video and animations to multiple 32x32 LED panels.Is there any software and hardware available now to do the things demonstrated in the DUO video. it shows live generation and display of video and a spectrum analyzer? What code was used to do this Are there FPGA schematics or ZPUino C code avaialble? https://www.kickstarter.com/projects/13588168/papilio-duo-drag-and-drop-fpga-circuit-lab-for-mak/posts/884233 Quote Link to comment Share on other sites More sharing options...
Jack Gassett Posted September 3, 2014 Report Share Posted September 3, 2014 Hello Howard, I have ordered some Wings to drive the RGB Panels but they won't be ready for at least 3 weeks. You could wire them up by hand in the meantime. Alvie made that code, we need to ask him if he is ready to release it yet. The goal is to make it all available with the first release of DesignLab, but we are not quite ready for that yet. I'm still getting everything in place for manufacturing, then I will focus on DesignLab. Let's see what Alvie says.Jack. Quote Link to comment Share on other sites More sharing options...
alvieboy Posted September 3, 2014 Report Share Posted September 3, 2014 Howard: I can upload all software/code this week. The HDL is already in github: https://github.com/alvieboy/ZPUino-HDL/tree/work-0200/zpu/hdl/zpuino/rgb The display is 64x32, using two cascaded 32x32 panels, with 24-bit color. I am now preparing a larger display, a 96x64, but with less bits per color due to technical constraints on the panel side (it will be 21-bit). Feel free to contact me at my email address (zpuino@alvie.com) for more details. Alvie Quote Link to comment Share on other sites More sharing options...
alvieboy Posted September 7, 2014 Report Share Posted September 7, 2014 Howard, We are now using email, but I'd like you to take a look at this set up I am preparing for Lisbon Mini Maker Faire: 96x64. Works perfectly @ 21 bits per pixel, at around 60Hz refresh rate. Requires two controllers on ZPUino, one for each 3x horizontal panel. Programming is however simpler, it just assumes a framebuffer of 96x64. Plays video streams very well. Quote Link to comment Share on other sites More sharing options...
hib1 Posted September 7, 2014 Report Share Posted September 7, 2014 Hello Alvie,The system looks very impressive.how do you sync two soft processors? how do you translate video to matrix values. I have to do it semi manually with a bitmap to C converter. Howard Quote Link to comment Share on other sites More sharing options...
hamster Posted September 8, 2014 Report Share Posted September 8, 2014 That will be one impressive setup. Humm.. the classic fire effect (http://lodev.org/cgtutor/fire.html) with a few ultrasonic distance sensors or microphones for interactivity...

alvieboy Posted September 9, 2014 Report Share Posted September 9, 2014 @Howard: It's a single processor. The two controllers have different framebuffers, so no sync is needed (they are synced by the very nature of the design). how do you translate video to matrix values. I have to do it semi manually with a bitmap to C converter. Well, I feed it with raw RGB stream, with the proper frame size. So I don't actually need conversion on the ZPUino side, just plain copy over to the internal framebuffer.Note: This is not compiled. The stream is sent through the serial port. For images, I do convert them to "C", or otherwise store the images/videos as files in a SD card or SPI flash. @Hamster: don't give me more ideas Ok, here's the state: it works, I can feed it full video @15FPS through the USB serial port (3mbps), and now, to make thinks a little bit more fun:$ ./mplayer -vo helpMPlayer 1.1-4.7 (C) 2000-2012 MPlayer TeamAvailable video output drivers: vdpau VDPAU with X11 xv X11/Xv gl_nosw OpenGL no software rendering x11 X11 ( XImage/Shm ) xover General X11 driver for overlay capable video output drivers sdl SDL YUV/RGB/BGR renderer (SDL v1.1.7+ only!) gl OpenGL gl2 X11 (OpenGL) - multiple textures version dga DGA ( Direct Graphic Access V2.0 ) fbdev Framebuffer Device fbdev2 Framebuffer Device matrixview MatrixView (OpenGL) aa AAlib caca libcaca v4l2 V4L2 MPEG Video Decoder Output directfb Direct Framebuffer Device dfbmga DirectFB / Matrox G200/G400/G450/G550 xvidix X11 (VIDIX) cvidix console VIDIX null Null video output mpegpes MPEG-PES to DVB card yuv4mpeg yuv4mpeg output for mjpegtools png PNG file jpeg JPEG file gif89a animated GIF output tga Targa output pnm PPM/PGM/PGMYUV file md5sum md5sum of each frame mng MNG file zpuino ZPUino RGB panel stream <--- LOOK HERE!I added support in mplayer for streaming to the RGB panel. This means I can play almost *everything* on it. The bad news is: panels do draw a lot of power if I display all whites. I was not able to power them properly yet, cause they seem to draw more than 10A@5V on this scenario. Displaying normal video from my webcam seems to only draw about 2.5A, so it might just work. Only four rows are lit at a same time. This means 96*4 RGB leds at about 6% PWM. I was expecting it to be lower, but... The panel logic itself eats about 250mA with all-black pixels.

alvieboy Posted September 13, 2014 Report Share Posted September 13, 2014 @hamster: I could swear I replied to you earlier, but seems to be gone:no need, thanks. I think I have it all sorted out now. Was harder that I thought: I had to split PSU for each of the panels, otherwise yellowish LED would light up. I'm ready now for the Faire: And, despite low PWM (at most 6%) it's pretty much visible under Portuguese sunlight: Good Quote Link to comment Share on other sites More sharing options...

If you read the description of that it would not be very useful as each voltage terminal is fused at 1.25A so not useful for supplying 10A@5V unless you want to short/change the fuse.

alvieboy Posted September 14, 2014 Report Share Posted September 14, 2014 Very impressive progress. As I try to follow along; What is the mplayer? mplayer is a video player for Linux. http://www.mplayerhq.hu/design7/news.html It supports most formats (if not more than Windows players) and it's fairly easy to extend (the beauties of open-source).

offroad Posted September 14, 2014 Report Share Posted September 14, 2014 >> they seem to draw more than 10A@5V you could use a four-cell NiMH battery pack as buffer. It's a hack, though. Or as alternative, a cheap BEC from the RC folks, a switching step-down regulator to 5 V:http://hobbyking.com/hobbyking/store/__40274__Hobbyking_YEP_20A_HV_2_12S_SBEC_w_Selectable_Voltage_Output.html Quote Link to comment Share on other sites More sharing options...
alvieboy Posted September 14, 2014 Report Share Posted September 14, 2014 @offroad: standard PC power supply (300W) seems to handle it very well, as long as I do distribute power evenly (i.e., one 5v+GND per panel, or per two panels at most). But even the PSU gets a bit noisy on all-whites. No excessive heat though - so it should handle it properly. I still have to power SoundPuddle with the 12V output, but should present no issues.

alvieboy Posted September 19, 2014 Report Share Posted September 19, 2014 And now ... we have menus: Easy as a piece of cake to work with:static void createMenus(){ subMenu *config = new subMenu("Opcoes"); subMenu *modo = new subMenu("Modo"); config->appendChild(modo); modo->setParent(config); modo->appendChild( new menuItem("Video", &onVideo) ); modo->appendChild( new menuItem("Bricks", &onBricks)) ; modo->appendChild( new menuItem("SoundPuddle",&onSoundPuddle) ) ; modo->appendChild( new menuItem("< Voltar",&menuSwitchTo, config) ) ; subMenu *controle = new subMenu("Controle"); config->appendChild(controle); controle->setParent(config); controle->appendChild( new menuItem("< Voltar",&menuSwitchTo, config) ) ; config->appendChild( new menuItem("Sair",&exitMenus) ) ; menuSetTop(config);}Menu is controlled with the WII Chuck, on this example.

alvieboy Posted October 21, 2014 Report Share Posted October 21, 2014 Panel was in display (actually, not for fun any more!) in a real event here in Portugal, the so-called UTAX (Ultra Trail Aldeias do Xisto). Two major races (one with 109Km [67miles], and another with 48Km [30miles]), pretty harsh mountain trail. Panel displayed times for both races, as well as classification and other goodies, all controlled via WiFi (with a TI CC3200 connected to Papilio Pro). I had to take photos with my mobile, which is *awful* at this. But here are some: Quote Link to comment Share on other sites More sharing options...

alvieboy Posted October 30, 2014 Report Share Posted October 30, 2014 ZPUino (on Papilio Pro) was connected through a serial link to a TI CC3200 LaunchPad board, which did the WiFI interface. Quote Link to comment Share on other sites More sharing options...
