How low can you go with the default setup and usb programming or even uploading using wifi??
Is it possible to upload an assembler binary?
It may seem stupid, but a lot of micros courses start off using assembler then moving on to C and greater things.
Has the tutorial for Arduino but obviously the spark core works much nicer as a first board in terms of hardware.
(Not wanting to overwrite the boot loader, the JTAG shield would allow for that, just want to upload assembler vs. Arduino)
