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

Hi all Please help me how to use DeltaSigmaDAC output in Papilio One 500 + LogicStart MegaWing + schematic library 1.4.2 Only simple example for DAC write value. Many thanks help Kamil

Hi Jack Many many thanks working great ! And thanks very quick response :-) Kamil

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

Great info many thanks :-)

Hi Jack My Papilio One im buy on Sparkfun.com. Your planning Papilio Pro and wings soon on Sparkfun ? Many thanks info Kamil

Is possible post example sinewave generation code for papilio ? Many thanks Kamil

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

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

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

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

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

Thanks this is working :-)

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
