This is the C++ workaround I've been using: // PROGMEM workaround for C++ bogus-warning bug in avr-gcc: // <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34734> // <http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=100009> // #define PROG_MEM __attribute__((section(".progmem.mydata")))
...and then use PROG_MEM where I would have used PROGMEM. Cheers, --Dave On Jul 1, 2012, at 8:49 PM, Rick Mann <[email protected]> wrote: > Also: this is a .cpp file.
