  1. Teensy 4.0,4.1 web pages need a warning about INPUT_DISABLE on Analog Inputs

    The Teensy 4.0 and 4.1 analog inputs require the digital inputs to be disabled, otherwise they have a weak pullup/pulldown circuit active that causes a small glitch around the midpoint, ~1.67V.

    Yes, those changes are good practice, and I have implemented them just now.
    However, they don't fix the userial.begin() hang problem.

    I suspect that the scope display drawing code is the source...

    I have done more testing and determined that the problem is a timing issue. I found that removing part of the splash screen text causes the clock to not hang in the userial.begin(baud) call.
    So,...

    Kurt,
    Hi. I apologize for the long response time, I've been dealing with various supply chain issues.
    I am glad to see that you were able to get the GPS puck and talk to it.
    My next question is if...

    Kurt,
    Thanks for looking into this. I have a pile of Teensys waiting for a solution.
    This USB chip is inside the puck. I've never seen it.

  7. Teensy 3.6 USB host hangs on userial.begin() if device already plugged in

    Hi, I'm using a Teensy 3.6 for my Scope Clock. I provide USB host support for a GlobalSat BU-353S4 GPS puck, using the TinyGPS and USBHost_t36 libraries. This puck uses an FTDI serial to USB chip. ...
  8. [queued] Scope Clock displays time on 3" round CRT, plays Pong, Tetris etc.

    My latest project to use a Teensy is a reboot of my Scope Clock. This is a product hat I first made 20 years ago, to display the time on a 3" round oscilloscope CRT. It has been redesigned to use a...

    I am pleased to report that the USB GPS system Just Works.

    I received the GlobalSat BU-353S4 GPS puck and connected it to the Teensy 3.6 via a USB type A connector soldered to the board.
    Then I...

    Thanks for the suggestion. I can see that the hardware interface for either is about the same amount of work (2 pins), but the serial NMEA software interface is much easier to get working quickly...
  11. Tensy 3.6 driving GlobalSat USB GPS puck

    Hi. I'm finishing up a project called the Scope Clock, which displays time on an oscilloscope CRT with a Teensy 3.6 as the controller. The last thing to add is GPS, since many customers want it.
    I...

    Hi. I'm new here, but I know a thing or two about microcontrollers.

    I'm working on a new project on a Teensy 3.6 with frequent SPI accesses as well as occasional Ethernet packets using a WIZ850io...
