Gemma Hoop Animator

Post by HerrRausB »

I finally managed to document the Gemma Hoop Animator code I showd off on this episode of S&T and uploaded it to GitHub.

Look into the source and header files or detailed explaination on how to use the animator.

What I forgot to mention on the S&T is, that I modified the LiPo by soldering a tiny SMD switch into the positive lead and gunking it to the LiPo, as I didn't want to disconnect this rather fragile connector everytime (see attached pictures).

I wish, the Gemma and all other boards of this kind would have such an on/off switch :-)

Here's a video showing the example animation together with the individual action definitions.

If you find this example sketch helpful enjoy it and have fun creating your own animations! :-)

Regards

Axel

I love this and want to get it working on my gemma! It's wonderful.

I'm using a mac and have (I think) successfully installed the GemmaHoopAnimator code. However, I can't get it to compile and upload to my gemma.

I can go into AdafruitArduno and open the Gemma Hoop Animator sketch. The GemmaHoopActionsList.h and GemmaHoopDefs.h also open up in tabs in the window.

When I try to upload GemmaHoopAnimator I get:

Code: Select all

/Applications/Adafruit Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/lib/avr25/crttn85.o:(.init9+0x2): relocation truncated to fit: R_AVR_13_PCREL against symbol `exit' defined in .fini9 section in /Applications/Adafruit Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/avr25/libgcc.a(_exit.o)
I haven't made any changes to the code at all. What am I doing wrong?

Thank you!
