I finally did manage to flash the EEPROM with v3.0. I had to give Arduino.exe permission as an accepted program with the Windows 7 Firewall. So folks having the same time out issue, please take note!

Yay, progress!

…also, once I figured all that out, looks like I made a critical error wiring the stick. Turns out the row of QDs closer to your stomach on the TE barrier strip is the signal and the one further away is the ground. Once I switched them around everything started to work. Oops. Either way, gotta go in and clean up the bird’s nest of wires since some lights don’t even light.

…the hoops I go through to make a stick pretty :D…

Jedi… After loading 3.0 … What colors are your buttons when pressed?.. Is your sparky from Focus attack.com?

143

@stevedave. The lights came on yellow the first time I got it working, or rather, they activated yellow, but that’s because I’m pretty sure my blue’s aren’t wired up correctly. If you look in the Sparky config.h, I think, you can see what they’re supposed to be. The Sparky I got was from Focus Attack, BTW.

Mine starts up red yellow green every time… But when i start playing the buttons just flash white only no matter which button I press or combination of buttons. When I first got the sparky and installed… The buttons were blue and other colors like the videos show,.

145

That sounds right, actually. If you flashed with v3.0 I’m pretty sure it defaults all activation to white. You’ll need to go to the configurator to change the colors.

Ok… That makes me feel better… Thanks

I had a question about the capability of the Sparky PWM. I’ve already purchased one to put into my next stick project, but I’m wondering if it’s possible for me to program multiple LED color scheme presets into the board? It would be awesome to be able to switch to a Neo-Geo color scheme when I play KOF, then a different scheme for Tekken, etc., without having to plug it in to my PC and manually change all the buttons every time. I know you can do some custom programming, but does the PCB have any memory on board that would allow for this sort of thing?

148

The EEPROM memory on board stores your last saved setup.

The other part you mention is future build

149

Well, you could technically get it to use multiple color schemes, but you’d have to hard code it, circumventing the configurator and the EEPROM memory.

Doing this would be rather straightforward.
The option state already exists for multiple button press read on startup

find this method


void SparkyClass::state(int mode)

look at this mapping



        /    \ /    \ /    \ /    \
        |  1  | |  2  | |  4  | |  8  |
        \ LP  / \ MP  / \ HP  / \ 4P  /
     
        /    \ /    \ /    \ /    \
        |  16 | |  32 | |  64 | | 128 |
        \  LK / \  MK / \  HK / \ 4K  /

figure out the sum of the button values you intend to press
ex LP(1) + MK(32) + HP(4) = 37

in the switch case below the mapping, add a case for 37



case 37:
  /*
    my custom color map
  */
  run = true;
char* pattern[18] = {
  "0000FF", // P1
  "00FF00", // P2
  "FF0000", // P3
  "FFFFFF", // P4
  "FFFF00", // K1
  "FF00FF", // K2
  "00FFFF", // K3
  "FFFFFF", // K4
  "FF0033", // 2x P
  "FFCC00", // 3x P
  "FFFFFF", // 4x P
  "FF0033", // 2x K
  "FFCC00", // 3x K
  "FFFFFF", // 4x K
  "FF0000",// P1 + K1 (throw SFIV & SSFIV)
  "0000FF",// P2 + K2 (focus SFIV & SSFIV)
  "00FF00",// P3 + K3 (taunt SFIV & SSFIV)
  "00FFFF" // P4 + K4
};
break;

find this method in the same file



void SparkyClass::program(char* pattern[])

in this portion



if(stored != -1)
    {
      char buffer[12];
      ltoa(stored, buffer, 16);
      color = buffer;
      user_pattern[n] = strtol(color, NULL, 16);      
      
      MESSAGE += " overwrite:";
      MESSAGE += user_pattern[n];      
    }

comment out the user_pattern line



if(stored != -1)
    {
      char buffer[12];
      ltoa(stored, buffer, 16);
      color = buffer;
      //user_pattern[n] = strtol(color, NULL, 16);      
      
      MESSAGE += " overwrite:";
      MESSAGE += user_pattern[n];      
    }

compile, upload, bingo

I recently bought a Sparky PWM SMD to mod my TE Round 1. My stick already has a ChImp installed and works fine. I figured that since I already have a ChImp installed that I could just install the Red and Black wires from the LED harness to the VCC and GND points on the ChImp. After using Nerrage’s video as a guide, the problem I ran into is that my LEDs do not seem to light up. I’ve tested the buttons on my PC and they are all in fine, working order. The stick is still fully functional on my 360, it’s just that I have no LEDs.

P.S. I’m a total noob at this but just to make sure, I don’t have to program the LEDs for them to work initially right? They should just light up a default color if I’ve done everything correctly, correct?

152

Hey all first post here. A little off topic but this is the closest thing I have found on the net to what I am looking for. I am making a custom pc case and I am using a dmx controller and led strip lights for the majority of the lighting. I also need a breakout with about 20 4 pin headers that will function the same as a rgb led strip to terminate 20 single rgb leds. Anybody have any ideas

153

So I’m finally getting a ps360+ (about a year after getting my sparky and leaving it in a container)
Now i have to refresh my brain as to how the heck it all hooks up.
Using what you told me last time, does this look right?:

I think I have it all good apart from the + and - on the sparky, does it work like this?
and the other pins are for the programing breakout thing yes?

154

Revival time!

Is their any hints about connecting this, Arc Eye 2’s, and a MC Cthulhu+Imp setup? Trying to figure out the next step after daisy chaining the Arc Eye’s together.

155

if i’m installing, a uila s flash, then what do i do with the white wire that comes off the uila?

156

I am at a complete loss as to where to go from where I am. I have troubleshooted every way I could think of but still cannot come up with a reason as to why my LEDs will not light. I have followed the guide video to what I believed to be perfection and have checked every lock and connection and still cannot understand why my LEDs will not light. The actual stick and buttons all function fine, however there is nothing coming from the LEDs, does anyone have any ideas or suggestions? I’m up for anything as I am not sure what to do now : (

157

[LEFT]You are using scotch locks, get rid of them and actually solder[/LEFT]

158

I’ve seriously considered it : /

159

friend of mine did this same made with scotch locks and didn’t work at all… gave it to me and removed all the scotch locks and soldered everything directly and now his stick lights up like its Christmas morning lol

How do I download the configurator files? the links in this thread require a username/password and the ones on the first page 404.
