Cant compile for attiny85 attiny family not supported :(

Im running the rgbstripsequence but it goes thru the sequence one time and then stops for about 2 minutes, how can I get the sequence to run continuously?

Bruno,

Thank you for implementing ALA_STOPSEQ in the master. It seems to work ok.

However, I have a couple of comments.

runAnimation()
This returns a boolean but you have placed a simple return with no value at the beginning when testing for ALA_STOPSEQ in both AlaLed and AlaLedRgb . Surely there should be an explicit false returned? I understand the default return will probably be a zero value int (=false) but isn't that, possibly, compiler dependent?

ALA_STOPSEQ
I'm guessing that if the caller does not call getAnimation() ALA_STOPSEQ will just time out and the animation sequence will just loop again.

Example
// 24 leds driven by pin 11 <---- this might confuse newbies as you used 10 leds on pin 6 below
rgbStrip.initWS2812(10, 6);

Regards
Brian

Hello, I am new to the Arduino world and am attempting a project for kitchen lighting. I have 261 WS2128b's wired up with a 5v 12amp power supply, injecting power every few feet of strips. Using the basic setup and connecting to Raspberry pi to control over internet. I cannot get the program to run with over 150 pixels, even on a test strip of 50 pixels, no commands will work after changing the pixel number over 150, could it be a memory issue? The board I am using is the Elegoo Uno R3

The FADEIN effect will switch the LED off after fade in and start over.
It would be nice to switch on a LED smoothly and switch off smoothly independend.
The smoothness with the parameter like in FADEIN.

basically i have a sketch with 5 leds and 9 button pushes. each push has a different effect and was wondering how to use the sequence in the example inside my sketch..
here is a small piece of it. ive used the functions as in the example but they dont seem to light up
if (count == 4) {player.playSpecified(5);
fadeon();
}

if (count == 5) {player.playSpecified(3);
                combo();
}

if (count == 6) {player.playSpecified(6);
               chase();
                                
               breathe2();                 
         
               
}

if (count == 7) { player.playSpecified(8);
                   fadeoff(); 
}

if (count == 8) { player.playSpecified(4);
    powerUp();
}

if (count == 9 ) {


}

Greetings, 🏞️

I've run into a problem on a project I was hoping to finish up shortly that involves the use of the ALA Library. As my feature list grew and supporting hardware came together, the libraries required to power the solution no longer fit within the SRAM on the Arduino Nano. I've now upgraded to the MKR Zero instead which boasts a luxurious expansion of SRAM to support all sorts of fun animations and palettes within the ALA Library! Sweet! Right!?

Well, as I try to re-compile my sketches, all of my other libraries port over just fine, but within the ALA Library, I'm seeing the dreaded do-not-pass-go before my eyes. Ugh! 👀

I want to help! ⛏️

SAMD21 Cortex-M0+ Board Background

Links to the SAMD core (MKR Zero variant) documentation and source can be found here.

The pinout description lives within the "variant.h" file within the source tree.

The more general support info can be found here (store.arduino.cc page)

Initial ALA compilation issue

I've tracked down the initial compilation error to line 114 of the "chip_includes.h" file. The "#if defined" commands are doing their job and trapping me within the [=[-[ #error "Unknown Chip!" ]-]=] state.

I see within this area of the ALA code that there are a few pinout mapping files supporting some of the most prominent chipsets for various Arduino packages. There seem to be minor variations within these files to support the various chip constraints, but I can't specifically attack this without a considerable amount of reverse-engineering and guesswork that I'm hoping someone might be able to help guide me on.

Is there some place within the documentation, or can I help write some?, that might help me understand specifically how to encode a new hypothetical "SAMD_MKR_Zero.h" pinout file to test out whether or not the ALA Library can be easily ported?

Sadly, my initial attempts have thus far been in vain to try and mimic the functional mapping files to the SAMD platform in order to tickle the right configuration parameters and get through compilation.

I presume it is also a safe bet that, once through these initial pin mappings, there may also be some some additional (deeper under the hood) incompatibilities that I'd need to then start tracking down after taking my first best guess at mimicking the other pinout diagrams.

A few questions come to mind when considering trying to contribute here or instead seeking out an alternative library to re-learn and re-integrate ... please advise:

1. Any pointers on how specifically I might start in crafting the requisite ".h" files to support this SAMD platform?
2. Do you have a checklist of some sort that you might use or be able to share with contributors as to what to be aware of when navigating the codebase?
3. Perhaps there's a few noteworthy documentation breadcrumbs within the code that I've not yet uncovered that might help guide me through?
4. Perhaps you might also have some sort of visualization or tech-spec drawings that you might be able to share that might logically arrange the functional components and notable hardware dependencies that the ALA Library relies upon?
5. In addition to the ALA specific code, what other logical hierarchies are involved and how entangled with the board pinout mapping files might they be? For instance, the AdaFruit library integration points seem like they shouldn't be show-stoppers in supporting a new board, but perhaps I'm mistaken?

Any info that might be worthwhile in hacking together a bridge to the SAMD21 board would be appreciated!

🌟 Many thanks! 🌟

I'm not sure how to feed fixes back as I haven't collaborated on a github project before.

I have forked this project to https://github.com/BNNorman/ALA and I've uploaded a fix to AlaLed and enhanced both Alaled and AlaLedRgb so that animation sequences can be stopped/started to allow for switching animation sequences.

I don't want to mess anything up on the master here so my question is "Do I just create a pull request from my forked repository?"

Thanks for any help.

no alert in arduino ide 1.6.5, success compile, but nothing happen with led

I'd like to use this library to animate some LEDs for a 'power up' sequence and a 'power down' sequence of an installation I'm doing.

Is there a way to:

• Run a sequence once
• Then continue other code once the sequence is complete.

Example

• "power up" sequence.
• "Steady" sequence (until a button is pressed)
• "power down sequence

I have modified the ALA library to 1) add the ability to drive the APA102 ledstrip using the APA102 library 2) include a modified FastGPIO to drive mega2560 digital pins 3) ability use different animation sequences on different sections of the same strip. The latter is useful if you have a long strip (memory permitting, hence the 2560) and want different animations on different sections.
I've also included a Colours.h file to define a shed load of standard colour names. Changed files are AlaLedRgb - now called ExtAlaLedRgb - lives in the sketch folder since I'm using it instead of the standard AlaLedRgb. And ExtFastGPIO - which now has pin definitions for the mega2560 . Read the header regarding which pins because some don't work with fastGPIO.

I am only able to test with WS2812B and APA102 - so am unable to test that my changes work with the other supported LEDs. Feedback would be helpful.

This is a zip of my sketch folder:-
ALA_DEV_1.6.zip

There may be some Serial.print's in ExtAlaLedRgb.cpp left over from debugging so it isn't really suitable for general use, just yet.

Note that this sketch requires the memory capacity of a mega2560 - the 2K devices just aren't big enough to drive my 144 led APA102 strip although the code compiles to under the 32K Flash size. I'm not sure how I can optimise the memory usage. (Any advice gratefully accepted)

You can view my video of two animations running on my APA102 led strip on YouTube here:-

Hope you like it.

When I'm trying to launch RgbLedSequence example I'm getting compilation errors:

RgbLedSequence.ino:22:28: error: 'colors_' was not declared in this scope

RgbLedSequence.ino:35:1: error: cannot convert 'AlaPalette' to 'AlaColor*' in initialization

RgbLedSequence.ino:35:1: error: cannot convert 'AlaPalette' to 'AlaColor*' in initialization

RgbLedSequence.ino:35:1: error: cannot convert 'AlaPalette' to 'AlaColor*' in initialization

RgbLedSequence.ino:35:1: error: cannot convert 'AlaPalette' to 'AlaColor*' in initialization

Would this work with Arduino 1.0.5?

I'm running this Neopixel sketch from the examples: RgbStripSequence.ino

What I've noticed is that after several cycles (it seems to vary) all the LEDs will turn white, and the program freezes and stops changing the animation. Sometimes there is a faint colored sparkle effect superimposed on the white.

I thought it was a power supply problem, but it happens with multiple different supplies.

I thought it was the WS2812 strip - but it happens with two different strips.

Any suggestions? Is this a hardware problem I can't see?

I've now used two different Arduinos (both Leonardo), three different power supplies, and two different WS2812 strips - and the same thing happens. The program loops through the animation sequence for some period of time, then the whole string turns white.

Unless I'm missing something, could this suggest a problem with the software - memory leak, millis() timing, too many animation sequences?

Could you add option for common anode RGBs? Value has to be inverted for those LEDs and using provided palletes is impossible with such LEDs.

analogWrite(pins[j],   255 - (leds[i].r*maxOut.r)>>8);

I'm using an Attiny85 in a simple project to control 6 RGB LEDs. I'd like to use this library with it, but it doesn't seem to support it. I'm using the method described here to program the Attiny85 using my Arduino UNO as isp: http://highlowtech.org/?p=1695. When I try it with the SimpleRgbLed sketch it says: E:\Arduino\libraries\ALA\src\pinouts/chip_includes.h:114:2: error: #error "Unknown Chip!"

NeoPixel library disables interrupts so millis() function is not accurate and introduces 'time drifting'.
It is possible to use a technique described here to have perfect timing: http://forum.arduino.cc/index.php?topic=335229.0

Hi ,
I'm new in programing and a want to implement a rotary encoder to set brightness
if i try to implement with this

rgbStrip.setBrightness(EncoderValue)

then this work but in all animation this sets color in strip to green and i don't know how this add to work this

And i want to change the favorite animation with push-button in rotary encoder

#Sorry for my bad english i'm still learning it

Hi, is it possible to make a potentiometer control the brightness in an animation?

also @bportaluri please tell me if you still work on the project, have the blogspot and will do any updates in the future

Hi there, just a video of a modified version of the ALA library driving some lights on a truck project i have been working on.

Thought it might be interesting to show some of the uses of this library (which is very handy code).

https://youtu.be/oQdsesSV4lE

Do you think it's relatively straightforward to add support for the Teensy 3.2?

I see this library supports Teensy 2.0 and Teensy ++2.0 already. What did you need to know about the boards in order to add support for those? Perhaps I can add support for 3.2 if I knew more about what you did with the other boards. Thanks!

Update library to the latest version

Hi

Is there a possibility to drive a SK6812 stripe? The Neopixel library seems to support now this Chip, with the standard ALA-Library the stripe didn't work.

How can I modify the code? I 'll use the ALA with the Ala-Web, this is an excellent application for my case.

thanks NEo

my config: 4m SK6812 RGBW stripe, 5V 20A powersource, Arduino MEGA, RASPI2 | ALA-WebIf and Ala-Arduino serial sketch installed and working

Sorry I'm a Noob to most of this please bear with me.
I was trying to use this Library with the Adafruit trinket.
But I get and #error "Unknown Chip!". I figured out this is because the chip on the trinket is not included In the Library. My question is would/could support for the trinket be add?

Any support for PCA9685 16 channel pwm driver? I have a link of the
library I use with it https://github.com/NachtRaveVL/PCA9685-Arduino

When using both libraries upon compiling the following errors occur:

Error compiling.

Tried tweaking the .cpp file my self, but I never got it to compile without errors.

Hi,
The library manager tells "CRC doesn't match. File is corrupted"
And even dl the zip file was not easy.

i compiled the SimpleRgbLed on an UNO and it use 22KB of flash memory.

Is it absolutely necessary all this space ?
On .cpp i view that you include neopixel code and tc code, but if an user need only use a single simple RGB led he do not need neopixel or other code.

Maybe it is possible write some ifndef for dinamically reduce code usage ?

After some time of run 2-3 hours the animation freeze and I need to reset Arduino :(

Hi,
I keep getting an error for missing the "#include <avr/io.h>" from "chip_includes.h" when trying to use it on an 8266. Is there a way to convert this library to run on ESPs?

Hi

My setup is an arduino uno driving a led strip of 150 ws2812b. (arduino v1.0.5)
It works nice at the begining, but during the demo sequence, something goes wrong, and it looks like some memory corruption occurs because of one of the animations.
Sometime, the number of led changes, sometime, the whole animation speed changes.

I suspect fire, or bubbles animation to cause corruption.
When I remove a these, everything seems to work ok.

hi there,
thanks again for this awesome library,
anyway i can make arduino remember the last animation was run ?

Hi there,
Thanks for the wonderful library, i was wondering if i could drive three or four WS2812 strip with different led counts on every strip, like can i use four different pwm pins on arduino to control those 4 led strips ?
i was looking into multiled sequence but seems like thats not actually suitable

anything you suggest ?
