    help using spdif input. I can't get it to work.

    I tested with and without the audio board (then with two other audio boards) it only worked without the board. I found this information: https://forum.pjrc.com/index.php?threads/spdif-input-and-output.45394/ it says: "As when using dual Audio Adaptor Boards, you need to disconnect Teensy Pin...

    help using spdif input. I can't get it to work.

    I think I'm figuring out that a simple SPDIF connection is not what it needs. I don't really know how to use an oscilloscope but that's my next step to try. I'll post the results.

    3V on the teensy board. the spec sheet said 3V is ok.

    help using spdif input. I can't get it to work.

    can anyone give me a lead on how to use the SPDIF input for the audio board? I am trying with a RX147L and have it wired to ground, vcc and pin15 running the code below. I have tried it with a .1uf cap between gnd and vcc as the spec sheet says. It can't be this hard but I'm doing something...

    Let's talk of possible new accessory boards

    I vote for boards that add LoRa, NB Cellular and GPS. Not so much becuase it's hard to add a module but for the integration we would get by having something like the Audio Design Tool. But more exciting to me would be to attach a Sipeed M1S (BL808) to add 100 GOPS NPU. train on laptop and...

    can I combine notefreq with various bandpass filters to detect more notes

    It seems that the lower notes are detected due possibly to their stronger amplitude. is it possible to patch the input into a bandpass filter then into notefreq to detect notes in higher frequencies? I try and there is no output even when running a 500hz sine wave. here is my code: #include...

    2000 LEDS APA102, super slow.

    Got frames per second for 2000 LEDs up from 4fps to 158fps -- problem solved. I did some testing and thought I would post the results. I tested sending data with FastLED[].showLeds() and FastLED.show(), sending the same amount of data to the same number of strips. The results are...

    2000 LEDS APA102, super slow.

    I've read every post on the topic of pushing high numbers of LEDs 10 times but must be missing something. I only have 2,000 LEDs and I can't get more than 6 frames per second. I'm using a Teensy 4.0 with APA102s on 26 pins for data & clock. I'm guessing FastLED.show() has to push 40K of data...

    Teensy 3.6 for 2 channel FFT processing. Use one or two

    Excellent point, I am controlling 2,000 LEDs in a music visualization. I am leaning to using two Teensy's just to be on the safe side.

    Teensy 3.6 for 2 channel FFT processing. Use one or two

    Will one 3.6 easily handle FFT processing for left and right channels or is it best to use two of them?

    OctoWS2811 moved to other pins to use as a simple buffer

    Great news. Thanks. As to the resistors: they are one more good feature I would not thought of and don't have to solder. I guess I will get better at it but right now soldering gets tedious, adds mistakes and looks bad. I misread the data sheet and soldered the 74HCT245 in wrong and...

    OctoWS2811 moved to other pins to use as a simple buffer

    Thanks for the reply! Ishould have been more specific. I’m wondering if the octo board requires all the pins be connected or if the board work as a simple level converter. Here is a post that talks about other pins doing things I barley understand and hope aren’t needed in my...

    OctoWS2811 moved to other pins to use as a simple buffer

    What pins do I need to wire between a Teensy 3.6 and an OctoWS2811 to simply use the onboard 74HCT245 -- assuming they are not stacked together? I have a Teensy 3.6 with an audio board attached and from what I have read it's not easy to use both boards together but the OctoWS2811 seems like a...

    Working on a BPM detector - am I stepping on anyone's toes?

    Thanks, I will look at those references. Are you trying to do real-time beat detection or analyze a waveform after the fact? There are lots of great sketches that do a fair job of beat detection I can refer you to but I'm sure you can google them just as well.

    A beat detector would be awesome. Any progress? Any way I could help?

    APA102 -- how many is too many

    Thanks, there is no magic answer I just have to test. I will start with one strand of 144 and work my way up to 2016 LEDs and see where it fails then cut back by half for good measure. You are right about the lore. It seemed like a better choice and probably is from a design point of view...

    APA102 -- how many is too many

    I would like to run between 14 and 20 1 meter strands of 144 APA102s in spectrum display and am not sure how many strands I can chain together. I will inject power as often as needed, power isn't the issue. I already bought 14 of the strands and prefer to use them as opposed to tossing them...

    Connecting nothing but a normal line out to the Audio Adaptor Board

    Thanks! It was just like you said, I connected an audio jack to a breadboard and wired the left and right channels to the Audio Board and it worked.

    Connecting nothing but a normal line out to the Audio Adaptor Board

    The Audio Adaptor Board is mind blowing as is the audio library and system design tool! I searched for a hour and while there were many answers none of them were simple enough for my level of knowledge. Here is what I'm researching: Is there a way I connect an audio line out from a normal...
