This brings in the actual real code: the "drivers" for the SH1107 display module, the i2c EEPROM chip, the actual UI for the thing, and the code "blink.c" program. Why is it called "blink.c"? Because all MCU projects start as a simple LED blinking thing. Including this one. And the name just never changes. The CMakeList.txt file then really brings the room together. Doing cd Software make prep make make flash should be more or less sufficient to build the thing and flash the end result (you'll need to have the standard arm cross-build tools available etc, of course) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
