Thanks for your reply! You're very right. I think for this type of application the SPI chipsets are absolutely the way to go. In this case, I don't really need high precision, so I was hoping to eek...

Thanks for the reply. I went back into the sketch to add Octo and I found some interesting when I removed the delay normally necessary to write LEDs on the 4.0. It's very finicky, but I might be able...

Thanks for taking a look I'll add the code with tags. I tried every pin for the ADC using adc1(A0-A7), I just moved it to A2 to more easily test different audio library configs.
Hello! I have been working through a number of microphones to get FFT working from the Teensy 4.0. All of the code worked great with the i2s microphone, but then I found out it spoiled the timing for...
That makes sense. I'm just a little bit confused that it seems to break output even when FastLED is only writing one light. It break output even if it only writes to that light once every second,...
Hello everyone! I have finally been able to assemble all my components for my LED project. It consists of:
1. Teensy 4.0
2. 1680 WS2813 LEDs
3. SPH0645LM4H-B breakout microphone
4. HC-05...
It's strange that you get such different behavior from the laptop and the desktop. Most desktop USBs provide around 500ma, and I imagine the laptop should be around the same. Do you have any...
Awesome. Thanks for weighing in.
Thanks for the reply I didn't know noise and ripple were different things I'll have to check it out. Good call on the little cap. I've added it to my schematic.
The project powers 1680 WS2812...
Sounds good. Thanks a bunch for taking a look and the recommendations!
Hello! I'm working on a project using the Teensy 4.0. I will be powering it via the 5v in port attached to a 5v power bank. The Teensy will be the only thing powered by this powerbank. Is a...
I've measured the voltage from 5V to ground and it is 5V. From 3.3 to ground it is .11V. I have to step out for a little bit, but thanks for the help.
Yeah, I've tried 3 cables so far, but can you describe from where to where I am measuring voltage? From the 5v pin to ground?
RIP. Thanks for your help!
No LED action at all, even after holding for 15 seconds.
Thank you for your response! I plugged it in and held the button for 15 seconds and then hit it again. I did this 3 times, but no results. None of the onboard LEDs blink anymore. I was running...
Hello, yesterday I was doing some very basic software testing on the Teensy 4. I don't believe that I had it connected to anything other than USB. When I tried to run some code on it today it did not...
That did it! I didn't know what to look for on the card. Thanks for take a look for me. I appreciate it.
Thanks for the help. I've toyed around with a few values and using the values suggested I get output, but when I reduce the gain of the sine wave to zero there output drops to zero. I don't want to...
Whoops! I added:
AudioMemory(8);
mixer.gain(0, 1);
mixer.gain(1, 1);
mixer.gain(2, 1);
mixer.gain(3, 1);
to the setup line and I seem to be getting some data now. Thanks for the...
Hello! I recently encountered a bit of a problem while trying to get audio visualization work. When I bought the Teensy 4 I did not know the extend of the audio library coverage. Because the ADC is...
More great information! Thank you. I thought i2s was a higher level system, but it looks like little i2s BOBs may be just as good as the analog one I have.
That looks like a great option. I don't need it to be a particularly clean signal, but it still seems like it does what I need. Thanks for your help!
A good suggestion, I'm hoping to avoid additional hardware, so waiting looks like the best option for the time being. Thanks for your help.
Hello! I just purchased the 4.0 and I was looking to do some FFT on live audio. I currently have a microphone that produces a 1.25V biased 2V peak to peak signal which I have been using with a MSGEQ7...
