Very fast reader for SPI flashes for Teensy 2.x.
Original code by Trammell Hudson.
Modifications and addons by Pedro Vilaça.
I have added a few new commands and options. Also added led flashing when dumping/uploading contents. I’m definitely not an AVR coder so excuse me some ugly things 🙂
To be used with Teensy 2.x devices (and maybe Chinese clones).
