This will probably sound crazy but is there a way piece of software to convert a spi sketch to a fastspi sketch? I am assuming it’s just a completely manual job since some commands are probably just missing.

What do you mean by “a spi sketch”?

this won’t work with fastspi unless i am crazy.

#include "LPD8806/LPD8806.h"
#include "SPI.h"
#include <avr/sleep.h>
#include "carrot.h"

//since data is on 11 and clock is on 13, we can use hardware SPI
LPD8806 strip = LPD8806(96);


int powerPin = 4;
int upModePin = 3;
int upColorPin = 2;

int upModeButtonState = HIGH;
int upModeButtonCycles = 0;
int upColorButtonState = HIGH;
int upColorButtonCycles = 0;

int CYCLES_DEBOUNCE = 2; //check the button for X ticks to see if it is bouncing
int MAX_COLORS = 8;

It looks like you will have to MANUALLY make the transition/port to the FastSPI library. Why did you want to use this particular piece of code? Was it because it was the first you have found, or perhaps you have seen it in action/prototype?

If you are looking for a great set of code to begin your testing/learning with, try this guy: http://funkboxing.com/wordpress/?p=1761

Hope this helps…

I took a look at the jubilee code and if you just want the effects that available in it then the demo FX code @Jon_Burroughs mentioned has something equivalent to those. I can’t tell what the ‘dither’ effect does exactly but I think the ‘random_pop’ effect in the demo FX code might come close.

Josh,

I made a LED hoop using Jubilee as ‘foundational’ code (ie it is heavily modified). I ended up using a four-button membrane keypad (http://www.adafruit.com/products/1332) to control 1) power 2) color 3)effect and 4)reset.

I also added a bunch of different effects and colors, which turned out to be pretty cool when hooping (see pics here: http://on.fb.me/1dbmcjA).

Here’s my code: https://github.com/teaker/Led-Hoop

Let me know if you’re interested in following what I did and I’d be happy to help. Good luck!

I stayed away from the ldp8806 since they cost so much compared to ws2811 and I should be able to get essentially the same effects.
I love the jubilee code but can’t really use it since the ldp8806 library is so differnet from the fastsp_led2 library I am trying to use.

Just FYI, I used these: http://www.aliexpress.com/item/-/822709329.html?tracelog=rowan&rowan_id=ae_pay_low_mail_template_en_US_2013-12-02
$52 for 5 meters isn’t bad, and they are very good quality.
