    Teensy 4.1 SPI1 for WiFi101 - has anything changed?

    Okay I fixed it. I noticed that I could delete the entire WiFi101 library folder without compiler complaints. I did a search for all things WiFi101/ATWINC1500 on my system and could not find any copies that the IDE was using. I just decided to go nuclear and remove all traces of the IDE using...

    Teensy 4.1 SPI1 for WiFi101 - has anything changed?

    Welp. I think I have a clue. I'm able to get the above code running on an old computer with Arduino 1.8.16 and the latest WiFi101 library straight from a GitHub zip. IDE 1.8.16 didn't have a library manager. On Arduino 2.3.4 it fails. Strangely enough, 2.3.4 seems to be ignoring my...

    Teensy 4.1 SPI1 for WiFi101 - has anything changed?

    Hi there. I just tried to compile some code I wrote for Teensy 4.1 and a WINC1500 on SPI1. I hadn't changed anything since it ran perfectly on Arduino 1.8.19 and Teensyduino 1.59. Now I'm using Arduino 2.3.4 with Teensyduino and I can't get the WINC1500 to work on SPI1 at all. i just get the...

    Alternate SPI works on Teensy 3.2 but not 4.1

    Aha! Thanks so much for clearing that up for me. I just relabeled SPI to SPI1 and my code has moved to the alternate SPI BUS. Reposting my corrected code so that others may see how this works in practice: I really appreciate this help and guidance, folks! #include <SPI.h> #include...

    Alternate SPI works on Teensy 3.2 but not 4.1

    Hi folks, I'm having a weird issue with my Teensy 4.1 and an Adafruit Airlift. I need to use the alternate SPI pins for the Airlift because of a hardware conflict. I'm using the SPI library and had success testing on my Teensy 3.2 but when I subbed in my 4.1 (with its different set of...

    Teensy 3.2 and ChronoDot 2.1

    Hi folks, I'm trying to wire a ChronoDot 2.1 to a Teensy 3.2 and having a hard time of it. I'm following the suggestions in this Teensy 2++ thread, keeping in mind the 5v/3v difference: https://forum.pjrc.com/threads/1045-ChronoDot-(Adafruit)-use-with-Teensy-2 Here's a photo of my wiring: Am...

    Problems w/ Teensy 3.1/3.2 and Adafruit SD Breakout

    Cool! Thanks for the clue :) I'll either grab one from this site or it looks like the Sparkfun basic breakout will work too. Cheers, -V

    Problems w/ Teensy 3.1/3.2 and Adafruit SD Breakout

    Hi there. I'm hoping there's a simple solution to this. I've been researching it for 2 weeks, but I'm still confused. I'm having a problem running the Arduino SD Datalogger sketch on my Teensy and an Adafruit SD breakout. I've wired it properly (const int chipSelect=10;). I get the following...
