Teensy
« on: July 14, 2017, 04:49:32 AM »
There have been a small number of posts here that have mentioned the Teensy, a set of  Arduino compatible ARM based micro-controller development boards.

https://www.pjrc.com/teensy/index.html

Recent developments include 16bit/44.1K audio boards:

and a graphical touch screen

All reasonably priced. Looks ideal as the basis of a range of audio projects including test equipment.

Anyone any recent experience with these?

Cheers

I can tell you about my experience with Teensy but please keep in mind I learned how to use development boards and minor programming using a Teensy, having only used an Arduino before then and having given up with some of the other atmega programmers. The projects i had done were neophyte at best and rather generic e.g. oled vu meters (which are actually really acurate btw) The teensy 2.0 and 3.1 feel like they were  designed for audio related projects (plenty of people use them for non audio stuff too) and its size, usb connectivity, and that you can run arduino codes through it which have a million projects at github make it very appealing.  Also using the arduino library also makes it versatile. On a single teensy i had rudiment daw transport control, a single fader controlled, an a/b monitor selector, an a/b input selector, and 2 x 5 led metering.  3.1 has more digital in outs than i could ever use while for analog it has 34.  So i could have added a bunch more like volume control, switch selection, mute, dim, etc...
As far as a teensy project goes its like i said beginners toys at best. As far as a monitor controller goes, it compared to other highly regarded stuff albeit totally diy looking and made by me.  The 34 in out is a lot considering you arent adding anything. I copy and pasted other peoples codes to but still had to modify it to fit what i wanted (so i kinda felt like i had done something)
Theres a ton to learn but pretty quickly one can start doing some creative things with it (i had to do a bunch of projects before i even attempted).
A lot of people out there are making some incredible projects that freely give all the info needed for one to make their own which is also really great.
So yeah i like teensy and will be getting more into it if time allows.

If there's a harder way to do this, I haven't found it yet.

Excellent. Looks like a good vehicle for audio projects then.
