    DeltaSigmaDAC help

    Hi Jack Many many thanks. I´m looking at MODPlayer example and find this REGISTER(IO_SLOT(5),1) = value Working great ! Very thanks help Kamil
  3. Hi Jack Many many thanks working great ! And thanks very quick response :-) Kamil
  4. Hi all Please help me with simple GPIO not working ! I´m use Papilio One 500 + LogicStart MegaWing + schematic library 1.4.1 bit file + ZAP 2.0.7 int led[8] = {40,41,42,43,44,45,46,47}; void setup() { for(i=0;i<8;i++){ pinMode(led,OUTPUT); digitalWrite(led,HIGH) ; delay (100); } } Light only one led diode same time. Not possible on more diode than one. Thanks help Kamil
  5. Great info many thanks :-)
  6. Hi Jack My Papilio One im buy on Sparkfun.com. Your planning Papilio Pro and wings soon on Sparkfun ? Many thanks info Kamil
  7. Is possible post example sinewave generation code for papilio ? Many thanks Kamil
  8. Hi all Is possible make VGA driver for papilio one 500 with better resolution ? like 320x240 monochrome ? How memory is disponible Spartan 3E-500 ? Thanks info about it Kamil
  9. 640x480 is nice info. Do exist this driver for ZPUino ? (320x240 or 640x480) I´m find this usefull project http://gadgetforge.gadgetfactory.net/gf/project/yavga/ but bad interfacing this - driver for ZPUino will be better. Thanks info about it Kamil

    Game Of Life VGA

    My first ZPUino and Papilio One 500 project :-) Conway´s Game Of Life cellular automata for ZPUino VGA version. This use random rule ! Kamil GOL_VGA.ZIP
  11. Hi all ZPUino soft processor not support floating point math ? Please help me im testing simple code in AVR8 soft processor and floating math working fine but with ZPUino not working ! Many thanks info and example

    Floating point math and rand() help

    Thanks info Today im testing RetroCade :-) Simple question do exist version bit file combined RetroCade and VGA output for Papilio One 500 ? Thanks info about it. Kamil

    Floating point math and rand() help

    sorry next few questions :-) 1. on your site is three different version bit file. Version with SID and VGA this two version not support deltasigma DAC ? 2. ZPUino support PWM on output PINs ? Please example thanks 3. Is possible make simple example how to basic run with SID POKEY and YM2149 ? Many thanks help :-) Kamil

    Floating point math and rand() help

    Simple question. Im make chua oscillator sketch with deltasigma DAC. This working but dont understand how to write two independent DAC value. ( example DAC0 = x and DAC1 = y value ) #include <math.h> float x = 0.5; float y = 0.25; float z = 0.125; float oldx = 0; float oldy = 0; float oldz = 0; float h = 0; float dt = 0.005; float alpha = 15.6; float beta = 28.58; float a = -1.14286; float b = -0.714286; int outx,outy; int pindac0 = 0; int pindac1 = 1; void setup() { pinMode(pindac0, OUTPUT); pinModePPS(pindac0, HIGH); outputPinForFunction(pindac0, 0); pinMode(pindac1, OUTPUT); pinModePPS(pindac1, HIGH); outputPinForFunction(pindac1, 0); SIGMADELTACTL = 0x03;} void loop(){ oldx = x; oldy = y; oldz = z; h = (b * x) + (0.5 * ( a - b ) * (fabs(x+1) - fabs(x-1))); x = oldx + dt * (alpha * (oldy - oldx - h)); y = oldy + dt * (oldx - oldy + oldz); z = oldz + dt * (-beta * oldy); outx = 32768 + int(13500*x); outy = 32768 + 5 * int(13500*y); SIGMADELTADATA = outx; } Please help me with example two independent DAC. Many thanks Kamil

    Hi alvieboy Yesss floating point working me :-) Many thanks great work !!!! Kamil
  17. Hi all Do exist working Gateman and SK-Synth source code and bit file for Papilio One 500 ? Please help me very thanks

    Gateman Poly and SK-Synth help

    Im testing it yesterday night and fully working. Must use GatemanPoly Patch Editor from this page http://www.fpga.synth.net/pmwiki/pmwiki.php?n=FPGASynth.GateManPoly and setting papilio serial port Com B. Nice work and great synth thanks Kamil

    Floating point math and rand() help

    My idea is studying chaotic attractors and fractals. FPGA and virtual processor is great for my chaotic and music experiments. Some example my old codes for arduino platform is here http://jlswbs.blogspot.com FPGA is better platform for interfacing devices this is very flexible. Kamil
  22. Hi all AVR8 soft processor support PWM pin on Arduino IDE ? Is possible make simple example ? (like dimming led) Many thanks
  23. JLS

    PWM question and help

    Nice example but existing IDE not support analogWrite command. Very please do new IDE and updated core. Papilio platform is great ! Many thanks your work Kamil
