Hey guys, I am trying to get a saber working and am running into a snag. I am using a teensy 3.2 with a prop shield, no sd card add on just the serial flash, the V1 setup. I want to use a neopixel blade so i tried using the config file "prop_shield_fastled_v1_config.h" ( i downloaded the most recent zip from the website 1.247) When I open the serial monitor I see a couple errors
SPI data conflict!
SPI clock conflict!

When I turn on the saber, those two errors just spam the serial monitor.
I tried looking at the troubleshooting page and googling and couldnt find anything on this.. anyone have any ideas?

You probably don't want to use FastLED, change the blade configuration to something like:

  {   7800, WS2811BladePtr<144, WS2811_ACTUALLY_800kHz | WS2811_GRB>(), CONFIGARRAY(presets) },

You may need to configure it some more to specify the right data and power control pin(s).

Want to buy Teensy board set 5-10 piece please leave your mail or contact me at yeahkess@gmail.com

thank you







The Teensy Saber is a light saber sound board based on a Teensy 3.2. The code is open source and the electronics is easy to build.
It has some unique features:

  • neopixel support
  • 44/22/11khz Audio
  • touch button support
  • multiple blades with different presets for each
  • supports both monophonic and polyphonic sound fonts
  • can play background music with other sounds
  • lots of free pins that can be programmed to do other stuff

Of course, most of the standard features are there as well.

All instructions, including how to build the electronics, software downloads and graflex chassis models can be found here:

I apologize if this has been covered before, but what are the specifications of the SD card for use with the V3 design? Is there a size limitation/preferred model/etc? Just ordering parts and couldn't find anything about it.

Most SD cards should work. Don't get an off-brand cards as some are slow and can cause problems with the sound.
Anything 1-16 Gb is known to work, bigger probably works too, but I haven't really tested that.

I've got a V3 board built which was working, but now I'm getting a "motion failed" error, what can cause this?

Problems like these are fairly unusual, so I have to speculate a little in what could be wrong, but: Most likely cause is probably a cold/cracked/bad solder joint on one of the i2c pins. These are called SDA/SDL on the tensysaber pinout, or pin 18/19 on the teensy 3.2 pinout. There are a lot of other potential reasons. The solder joints under the motion chip can crack, the i2c pullup resistors can be damaged or pop off, there could be a short somewhere (Again, on the i2c pins)
