    C++ Question (Warning: pointers inside ;-)

    It's worth noting for portability purposes that uintptr_t is not a part of any ANSI/ISO C++ spec prior to C++11 (or AFAIK any C prior to C99).

    Teensy 2 vs Teensy 3 GCC error with C99 struct init by member name

    Sounds to me like Paul is saying Atmel isn't stopping PRODUCTION of AVR. They are stopping NEW DEVELOPMENT. Makes sense to me. There are some great AVR chips; for example no ARM can match the low power state some of them have. We're taking nanoamps in some cases. But they've got the segment...

    Teensy 2 vs Teensy 3 GCC error with C99 struct init by member name

    If you are trying to do what I think you are, I have wrestled with this mess; what I call missing "sparse init" of structs in C++; to the point of physical sickening. I despair that C++ will EVER standardize something as simple and elegant as C99's named struct element init. Even C++14...

    OSH Park currently selling Teensy 3.1 at an amazing price

    Just wanted to mention, I made a miserable order of a single board and the service was excellent. It came with blinding speed via first class mail. Make sure you don't throw the board away with the envelope!

    Audio For Teensy3 - What Features Would You Want?

    This looks nice indeed! Good design choices.

    What wire to use?

    I second using either 28 or 30 awg kynar. You will need a good special purpose stripper. Forget trying to knick it with dykes and pull the insulation off (voice of experience). Actually you can manage it if you are good, but life is short. I found this to be the best stripper...

    Teensy 3.1 & Teensyduino 1.17 Released

    Bravo on the 3.1, Paul! Evolutionary but very cool.

    Is there something wrong with my understanding of pointers?

    Mostly very true, but does not affect the simple optimization I did at all.

    Is there something wrong with my understanding of pointers?

    The array version does one compare, one increment, one addition, and one indirect store. The pointer version does one compare, two increments, and one indirect store. I fail to see any significant difference in operational complexity. You don't say how much the execution time difference was...

    Step past Arduino enviroment?

    If you're not comfortable with emacs or you want more frills, and you're stuck with Windows (ugh), it's Eclipse all the way. In linux, kate is pretty darn good. I think you can run kate under X11 using cygwin on Windows.

    Fpu?

    Thank you for the info, and thank you VERY MUCH for the WOOHOO! heads up on Teensy++ 3.0. I am excited by the regular Teensy 3.0, but I am wild with anticipation about the ++ version.

    Fpu?

    1) I understand the Freescale part used does not have an FPU, but other similar ones do. Is this true? 2) Is there a part with the same pinout which DOES have an FPU? Could a variation of the board be produced with this part? Please?

    Teensy 3.0 "beta8" Software

    Awesome, Paul. This is a most exciting development project to watch, and progress is incredible. The board is an absolute marvel and the price is fantastic (that really matters to some of us basket cases :-)

    Teensy 3.0 ADC details

    Looks from the graph like if you've got plenty of processing power to spend, depending on A/D sample rate requirement, a median filter would be made to order to get super high precision. Generally a lot of applications don't care that much about absolute accuracy, but monotonicity, precision...

    Teensy3 makes Arduino development environment hang

    An excellent explanation, Paul. I'm going to stick my neck out and say I've seen rxtx lock up both OS X and Windows XP solid as well as linux. I agree fully that rxtx is trouble, but I'm not willing to make them the fundamental goat. All they are doing is calling system drivers for the serial...

    Teensy3 makes Arduino development environment hang

    Here's the message that disappeared. RobM, thanks for the info. Just to add to the saga, I'm pretty bummed right now. I just had my ENTIRE 64 BIT RHEL6.3 SYSTEM with 12GB of apps running freeze up solid while running the Arduino IDE. No mouse, keyboard dead, no disk activity, power button...

    Teensy3 makes Arduino development environment hang

    The message "This device cannot do calls on its own..." is a filter that is in there where something decides that NetworkManager cannot use the device as a mobile broadband connection. The message of mine that got lost was just saying I believe you are going to see freeze-ups sooner or later...

    RobM, thanks for the info. Just to add to the saga, I'm pretty bummed right now. I just had my ENTIRE 64 BIT RHEL6.3 SYSTEM with 12GB of apps running freeze up solid while running the Arduino IDE. No mouse, keyboard dead, no disk activity, power button wouldn't shut down gracefully which means...

    Teensy 3.0: What doesn't work yet?

    I'm interested in the same thing; OP is MIA; so I'll tell you what I'd like to see at any rate. <feature x> working - fully as far as is known <feature x> partially working - except for <particular case> <feature x> for all <feature x>'s :-)

    Nice find on the fix. That's a good one to remember in case that ever happens to me.

    Teensy3 makes Arduino development environment hang

    I'm on a 64 bit RHEL6.3 clone. I tried your last example and no problem whatsoever. I tried both Tools -> Serial Monitor from the Arduino IDE, and minicom, with no problem. It's not clear to me why you say "the development environment" hangs if you are using putty at runtime. Can you clarify...
