ws2812 example does not compile under Windows MinGW

[buttim]

Tested with SDCC 4.0.0 #11528 (MINGW64)

The error reported is: main.c:5:19: fatal error: ch554.h: No such file or directory

You have to change

#include <ch554.h>
#include <debug.h>

to

#include "../../include/ch554.h"
#include "../../include/debug.h"

How are you building it? Using make (from Qt, but installing it from elsewhere should be similar), it seems to work for me:

If you're compiling by hand, you'd need to specify the include directory (for example): -I"C:/Users/blinkinlabs/Blinkinlabs-Repos/ch554_sdcc/examples/../include"

Yes, I'm using make. But I checked and the make executable being used was from cygwin, not MSYS. Cygwin uses paths relative to /cygdrive/c, which SDCC cannot understand. Everything is fine with the right one, thank you

Great!
