    Of course it refers to the array index! I can't believe I missed that.

    For now, I'm inclined to pad the array and maintain the established numbering.

    I will finish populating the rest of the...

    For the record, the PJRC adapter board worked flawlessly. My jumper wires test fine, but apparently they are long/bad enough that the fast SPI bus does not like them. Word to the wise!

    Extended Pin Numbering

    ISP, FOR Teensy

    A lot has been written on using Teensys as programmers for 8-bit Atmels. I'm wondering if someone could point me in the right direction as to how I could instead program a Teensy from another MCU.
