There is a little more spread at the base of the odd harmonics, although the FFT sizes are also different. I had expected more of a difference, and I was wrong.
I took the Waveforms Audio example, set the frequencies to 1000Hz, wave type to sine, and maxed the levels with
sgtl5000_1.lineInLevel(0);
sgtl5000_1.lineOutLevel(13);
And looked at the line outputs with my QA403 audio analyzer:
Which...
I would expect to see a big difference, if the sine wavelength is not an integer multiple of the exact sampling frequency. See

@Paul Here is a replacement USB MIDI web page, derived from the current page and adding guidance on this aftertouch issue. Feel free to use this, if you would like. I didn't see the website on GitHub, so could not send a pull request.
This differs from the Arduino MIDI library, which overloads the function name (and thus, can't be extended to allow an optional cable number)

Hello Defragster
So it runs fine...
Yes, capacitors between the analog pin and AGND. Think of the pots as their own isolated little system which connects only to Teensy analog input pins, 3.3V and AGND. You should have absolutely no connection from those pots to anything else on...
> The MCP4822 is only dual but Edges has 5 audio outs, so how is it doing this?
Out 4, which can be a triangle wave, uses the DAC; outs 1 to 3 are digital pulses so don't need a DAC. Out 5 is simply the analog mixture of the other four.
You really need to run tests on actual hardware. As we've seen already in this thread, small details matter.
The peripherals (and/or other stuff) are consuming as much power as the CPU. You wrote "deepsleep in between the new data arrivals" in...
Okay nevermind. I did "copy link" from the link in the announcement post, and that actually is https://www.pjrc.com/teensy/td_156/package_teensy_index.json which is different to the text of the link
From Github:
Does that mean that each pin used for FreqMeasureMulti needs to use a different FlexPWM timer? Or just not share a timer with a different function, like PWM? I wasn't sure, reading the docs.
(I have a project that needs two...
My current project needs two RGB LEDs as indicators. I'm using Adafruit Pirhana common-anode LEDs driven by PWM.

I'm using at 146.48kHz to get 10 bit analogWrite resolution. I notice on a scope that the PWM...
Just wanted to send a very heartfelt thank you to Paul for building the Teensy 4.1 microcontroller board. The context of this is my team just had our first successful test flight of our 4 tonne drone for fighting forest fires. The entire...
In a classic example of everything takes longer than anticipated, after I got those 2 units soldered I didn't really have a plan for how I would test them. While the Phazerville firmware now has low-level drivers for the new hardware (most of it...
My first board was hugely wasteful of space, poorly routed, and I could do a lot better now. The important thing though was that I did it, and it worked, and I learned stuff.
Autorouting tends to give poor results, KiCad makes manual routing...
I second the recommendation for OshPark. I have ordered a number of PCBs from them, and I have never had any problems that could be attributed to the manufacturing process. I've also used a few boards from JLCPCB (one that I created/originated...
Why would it need a hub? This seems to just need a USB-C to USB-B cable, which is readily available, plus the USB host panel connector which has a USB-B socket.
