    Bingo, After some fussing with Ublox-Center, I was able to configure my M8N to emit what your code was looking for. Works great and will allow me to clean up my data-recorder code. Thanks much, john

    jferguson replied to a thread uBlox Library in General Discussion
    Hi Brian, I had thought, apparently wrongly, that the 10 Hz binary signal from an M8N could not include the clock data. Accordingly, my 2016 flight data recorder included a clock module. In addition to having...

    Hi Brian, I'd been successfully using another UBLOX parser, but saw that you'd updated yours and so ..... Using the Master library with UBLOX8.h and UBLOX8.cpp, the included example needs some work. It loads UBLOX.h...

    jferguson replied to a thread SBUS Library in General Discussion
    Hi Brian, I have now integrated your sbus code with my flight recording code and it works great. I decided to use x8r.read() rather than readCal because I will be able to use this form of output (somewhat edited) to...

    Hi Brian, Now that I have one channel printing fine, I want to move on to printing the 4 channels my project needs. What you've done is if(x8r.readCal(&channels, &failSafe, &lostFrame)){ ...

    That's good. While we're here you suggested that my aerodynamics recorder might want to see control surface deflections. My thought had been that I would relate control input and airspeed to rate of change in in...

    Boy are you quick. I'd thought that the inverted logic applied to the teensy as well as the Mega. Wrong?

    Here is what I've done: Teensy 3.2 - powered externally with 5 volt to Vin port GND from power source to Pin 0 input from X8R sbus port through 1k resistor to base of N3904, gnd to emitter, output to teensy pin 0...

    The wire you see in the top-side photo is the one lead which couldn't be confined to the back. I've made maybe 3 dozen boards for different purposes and this is the first where I just couldn't do it without a crossing....

    Hi Brian, I've looked at your site and it's clear you are doing what I'm trying to do and likely much more successfully, but then I'm doing this for fun. two more photos, one of the flight recorder showing the Teensy...

    Brian, This project is 3 years old. The objective was to develop expertise in semi-autonomous (plane takes off and flies itself on a prescribed route and lands itself) very small fixed wing aircraft design. Although I...

    Hi Brtaylor, Can you comment as to whether what I describe below can be done more or less directly with your code, and just in case, you see something crazy about what I'm proposing, let me know? I'm in the midst...
