Hello and thank you for your most speedy response.

In this situation I am not using Teensy hardware, this is running on WeMos D1 or Node MCU. I posted here as timelib is (I believe) a PJRC...

Greetings all - I hope you can help with a strange issue that I appear to be having with the time library timelib.h

This is a simple project based around getting time from an NTP source via a WiFi...

Greetings all,

I am developing a project - an Audio Spectrum display using IN-13 Nixie tubes to be driven from a Teensy 3.5.

So far I have tested with an Arduino which generates PWM @ 5V.

I...

I believe that is what I am looking at and I was hoping to use some of that code as the basis for my project. I can see that the example is using fft 1024 and assigning the bins to each of 60 bands....

Progress has been made - I am now in possession of a Teensy 3.5 and I have loaded the SpectrumAnalyzer example and seen the output on the Serial Monitor.
I want to re-work the code for 20 channels,...

I think I shall be avoiding interrupts for now - thank you for the tip.

I also found the recommended input circuit over at http://www.pjrc.com/teensy/gui/?info=AudioInputAnalog - which I shall...

I have been looking around and had intended pinching the audio input details from here: https://hackaday.io/project/8599-teensy-audio-spectrum-analyser
Does that sound like a plan?

That is super helpful. I have installed the software and have taken a look at the examples. Teensies has been ordered - all hugely exciting - this has to be better than building and fine tuning...

Thank you very much for this.
Arduino IDE already here, Teensyduino downloading as we speak and Teensy 3.5 (for the 5V aspect) ordered.
I shall look at the sample sketches - by 'different hardware'...

Hello Forum,

I only learnt about Teensy a couple of hours ago and am quite excited about the prospects of using it for a project I have in mind.

I want to build an audio spectrum display split...
