I've updated a Teensy with a Raspberry Pi Zero W. If you need the Pi desktop environment to install Arduino and configure things, the Zero is so slow, it's barely usable. Once you struggle through that, though, the...

That's an excellent idea! Maybe this thread will be helpful: https://forum.pjrc.com/threads/44587-TTS-(Text-to-Speech)-Library-Port

Have you looked at https://forum.pjrc.com/threads/13987-Teensy-3-0-capactive-touch?highlight=touchread+timeout ? I think there's a need for a library on GitHub to support non-blocking touch sense. Posting code on the...

Thanks, Paul. I did grab the latest udev rules. I'll update my Arduino/Teensyduino soon.

Tried an experiment with a bare teensy LC that shows some promise. Using touchRead() you can tell the difference between the following Teensy held its USB cable plugged into the PC Teensy held against its...

Now that /dev/ttyACM0 is back, I can select it in the Arduino IDE Port menu and things are back to working. Well, working with a workaround. I don't think the Arduino IDE serial monitor should have failed the way it...

Thanks, Kurt. I think you're probably right. My first symptom was that the Arduino Serial Monitor failed to open with an error. Unfortunately, I didn't write down the error at the time. When multiple projects...

Progress! I tried a different Teensy that hadn't been updated lately and that uses USB Serial. /dev/ttyACM0 appeared as usual. I'm guessing that somehow the Arduino IDE settings got confused between two projects and...

The teensy still functions as a keyboard device, but USB-serial still isn't working. Still no /dev/ttyACM0. Tried various things. sudo modprobe cdc-acm sudo modprobe usbcore sudo modprobe ohci-hcd sudo modprobe...

Perhaps the Pi doesn't have the needed USB serial driver installed. There should be a device like /dev/ttyACM0. You might also need to mess with stty to configure it or use a terminal emulator like screen, picoterm,...

Recently, I was able to build and run teensy_loader_cli for OpenWrt 19.07.7 running on an GL-iNet Mango GL-MT300N-V2 Mini Router. As I mentioned in another thread, I'm able to reprogram the Teensy over the air, but...

I've done something like this with plain serial. It's a little wonky if the serial port also has all the console messages. You can disable the console messages, but then debugging the system gets harder. What I do...

You could try posting picture and giving a bit more information. What exactly did you do? What did you expect? What did you observe? What have you tried regarding fixing it?
