Teensy/TeensyStep

[Kurt admin]

Hello,
I have worked myself into a corner with the Teensy/TeensyStep combo. I struggled for a while to find something that would do the task at hand with my limited skillset and the present prototype is a Teensy 3.5 running the TeensyStep library. I naively thought I would be able to go with a 4.0 for the final project, but by my reckoning, the author of the TeensyStep library apparently concluded a while back that it wasn’t going to work with the 4.0. As you know, The 4.0 is pretty much all that’s available now. I’ve seen a couple of 3.X examples for sale at scalper prices. So it appears that options to work with TeensyStep are currently foreclosed. I could attempt to squeeze the one example of the 3.5 I have into the very limited space I have for a PCB. So I though I would check here to see if, in fact, the TeensyStep library has ever been updated for 4.0 (I can’t get even the sample TeensyStep code to compile with the library I have. Or failing that, if anyone has or knows of an example of the smaller footprint 3.X Teensy that’s available. This is a one-off project, so I only need to track down one example.
Thanks
Kurt

Chatgpt says it knows about arm cortex m7 code/instructions. You might try asking it to convert/update the files that are failing to compile.

A while back, I salvaged a ton (dozens!) of barely-used Teensy 3s from a pile of professionally engineered boards a friend built for work and then had to discard. I suspect a number of them are still in the free box at Ctrl-H. And I think I have at least two of them lying around here at home. You’re welcome to any of them.

Hey Jared,
Thanks for the offer. I live in Albany. Any chance I could set up something to have a some sent this way. Probably send a USPS label to slap on a box or envelope?
Which reminds me. I have a box full of stuff I should probably drop off at Ctrl-H next time I’m up in Portland.
BTW, I have a small stash of vintage power supplies that came from The Black Hole in Los Alamos the I used to live in Santa Fe. They are heavy and kind of interesting. Is that something anyone might find interesting at the Ctrl-H free pile?

Nathan,
Interesting idea. Probably above my pay grade.
