    I think I found my problem. i used to use an Ardhuino Uno with RST shorted to ground as a signal booster to connect the Ublox GPS module to the USB port on the computer. The Uno is a bit clumsy for this and I thought...

    Brian, I apologize for waltzing you through all of my difficulties, but they seem to continue. I'm now confronted by the possibility that two of my Ublox M8N's are counterfeit. Both have lost ability to talk...

    Hi Brian, The may be more of an aesthetic issue, but i need a routine to wait for the Ublox to start emitting real data before continuing my program. I'm using the clock functions to name the files I'm recording on...

    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?
