    Program button gets the bootloader LED to flash and flicker for a bit.

    Curious how I might have clobbered the USB state.

    Teensy 3.5/3.6 port/pin map?

    I do a lot of bit banging and I'd like to see the PORTx / pin map for the 3.5/3.6 devices.

    The map for the 3.1/3.2 devices has been real handy.

    Zeroing the buffers when I release them and still I get -1.

    Checked all the solder connections.

    Is there some API setting I'm missing.

    Audio board power consumption, etc.

    Hi,

    I've used Teensy 2's & 3's with a number of LED projects, but now I'm investigating using one for a 4-channel 44.1 kHz data logger.
