  1. R

    Last of my public apologies, pretty sure.

    EDIT: Sorry, below is obviously not well written - I am OK, if I was still at my weakest I would still just be staying away (basically). - BUT, thanks for being concerned; honestly - I have been well taken care of and have barely suffered even a little aside from embarrassment and a tiny little...

    Fresh Teensy 3.1 not retaining code when power cycled.

    Fresh, first time out of the bag PJRC shipped it in and when I connect and upload code to it all appears fine and it appears as the expected device and functions in the expected ways until I unplug it and plug it back in. This behaviour persists when using...

    lock bit(s) for MK20DX256VLH7

    The TD 1.21 features list includes mention of adding lock bit support for Teensy 3.1 but Google doesn't find me any info that I can use to attempt implementation. I tried experimentally to simply set FTFL_FSEC to 0xFF as a response to a specific sequence of chars over Serial but on trying it I...

    Audio Library problem using Arduino 1.6.3 & TD 1.22

    If anybody can suggest what I have broken, or perhaps point out a post/thread/memo I must have missed, I will be very grateful indeed. I finally got a TLV320AIC3254 to play with and was setting about making a driver I might be able to contribute to the library later but I am a bit stumped with...

    Teensy Loader 1.21 does not remember my choice...

    When I untick 'operation->automatic mode' in an instance of Teensy Loader and then close it and later re-open it I find my choice discarded. Is that intentional? Have I missed something nice and obvious that would make my choice stick between instances? Arduino 1.6.1 with Teensyduino 1.21 in a...

    Curious stuff about the Flex Timer Module in Teensy 3.x (3.1 at least)

    I wanted a free running 32 bit (unsigned, of course) timer with greater 'granularity' than micros(); so I started looking and settled on FTM1 as being the thing to use. First curiosity: If the FTM_SC_TOF bit is not reset very early in the interrupt handler routine the interrupt fires again for...

    Controlling SGTL5000 (TWR-AUDIO-SGTL) using Teensy++ 2.0

    The Teensy++ 2.0 I am using is still running at 5V, the SGTL5000 has max voltage (including/espeically IO) of 3V6 and I have taken some care to make successful connections between GND, SDA & SCL on the devices without being too naughty, I'll happily detail how I think I've done that more than...

    How to enable CLKO on Teensy++ 2.0

    I read in http://forum.pjrc.com/threads/21825-Fuses-Teensyduino-sets-for-Teensy-2-0 that Paul strongly recommends not messing with the fuse settings but I am trying to use the Teensy++ 2.0 with an audio codec prototyping kit which expects a clock from the 'host' so it seems to me my most...
