What exactly is the configuration there? The strip which lights up now, where is it connected to?? To the second ethernet port?? Try to send data to all LEDs and check all 8 outputs. It is possible to use any pin now and to define pins. Maybe...

I just noticed that in the previous post, the Kaiser window needs the Bessel function code. To solve that, you can paste the following into the.h file, and remove class reference from the call. /* float i0f(float x) Returns the modified Bessel...

Here is an 1024 point Fourier Transform that improves the dynamic range of the Teensy Audio library class AudioAnalyzeFFT1024. This increase is due to using floating point processing inside the update() function. As a library element it is pure...

One of the "use cases" I'm really hoping to address is the people wanting to build huge MIDI controllers with tons of analog pots, rotary encoders, switches. Or similar for audio synth projects where a large number of knobs or buttons control...

Hi Tom, Thanks for your info! I just looked at the Rock5B USB specifications again: USB C 5V up to 3A USB 2.0 5V / 0.5A According to information from this forum, the Teensy 3.5 needs about 100mA. Then one of the Rock5B USB ports should easily...

I think you might want to ask yourself a better question first: what is the maximal real resolution my faders can meaningfully deliver ? (maybe use a simple test jig and and i2c analog external multiplexer with high resolution ADC and/or a scope...

14-bit resolution in MSB/LSB CC pairs is just an artefact of how MIDI transmits data. The question then is not "do I need more than 16k steps" it is "do I need more than 128 steps". 10-bit fader value is 8 times more precise than a 7 bit one.

5V needs to be cut. GND has to be connected. There exist USB cables with a switch which in my experience do not work because the data lines are missing. I am using a USB hub with power switches for each port to connect Teensy devices with...

Just a wish list: Something like the old propshield board with and without the IMU. Would be nice to have a DAC on board it :) so things like speech can be used. As for IMU probably something like the BMI270 and the newer BMM350 since the...

Continued follow-up, it works! I foolishly also flipped the collector and emitter on MOSFET Q1 in the schematic, but was able to whitewire a fix. In hopes of contributing back to the community, below are images of the project and some lessons...

Hi All, I ported the TAL NoiseMaker virtual analog synth to run on Teensy 4.1. The synth is implemented as an AudioStream object with stereo output which you can incorporate into your Teensy Audio Library signal flow. It comes with a soundbank...

It is possible that there is something wrong with the configuration of the Octo library - although I don't see anything. 10 Leds? Your strip looks longer btw the color order just changes the order ... even with the wrong order you would get the...
