    Any thoughts?

    TL;DR:
    Do I risk damaging a GPIO on Teensy 3.2, if it is connected to a source of 7v via a 4 KOhm resistor, and the source of that 7v is such that it drops to 0.2v when as little as...

    Can this fry my Teensy 3.2?

    Hi,

    I need to be able to switch a load (8v , 0.5A) on/off with a Teensy 3.2.

    I was initially planning to drive a MOSFET with Teensy, which would turn the power on/off on a traditional...

    That'a a great question. The main value of the product is not the firmware, its the software running on the PC and the service that the software is using located in the cloud.

    I'm really looking for something that would not require user pressing the rest button on the teensy. The electronics are deep inside the device we sell.

    So, this seemed promising:

    OctoWS and using ports 5-12 on Teensy 3.2

    Problem is, when I use OctoWS, one of my steppers...

    RE: Teensy LC and OctoWS library

    Thanks, guys. I am so used to OctoWS, that I am a bit afraid to switch and face new/unknown bugs, refactor code, etc :-)
    In your experience, is FastLED reliable?

    Teensy LC and OctoWS library
