    I'm not quite sure what you're trying to say. Looking at the specs of a 74AHCT595 chip, it does state that:



    Specifically, for the 74AHCT595, a threshold of 2.0V for HIGH is mentioned when Vcc...

    I just soldered up a minimal connector using just the one required 0.1uF capacitor on the magjack. It works beautifully and the UDP speed tests I've done show speeds over 90mbit/s.

    Yep, thanks! It's a valid point, as I've been bitten by this before (the worst was one a previous projects where I was using 74HC245 instead of 74HCT245 level shifters, which was fine in lab...

    For this project I'm using the 74AHCT595 as recommended in the documentation in the first post, whose outputs are apparently level-shifted to 5V. However, I don't have an oscilloscope handy to...

    So, I just tried this library on a Teensy 4 with a PCB that is meant for a new interactive art LED installation. It works! Mostly! :)

    Here's some questions / feedback:

    I think so! I haven't really modified the library myself either, but I'm following several contributors who have, for example Yves Bazin, who wrote a similar parallel output library for the ESP32:...

    This looks extremely interesting! Have you looked at extending it to a second flexIO for more outputs int the meantime? Also, is there an integration with FastLED already so I can save myself some...

    Hey Crees, I'm also super interested in using the T4 as a platform for driving large scale LED projects, especially with the prospect of getting fast USB Ethernet at 20+ Mbyte/sec going to shovel...

    I've been using the Teensy 3.2 in my experimental arcade game Line Wobbler (mostly just using the wave generator in various ways) and simply using a capacitor and the DAC pin to a small amplifier...

    Hey all!

    I'm Robin, and I just wanted to show off a little project I've been working on called Line Wobbler (project website).
    It's a one-dimensional dungeon crawler based on a teensy, a spring...
