Re: [avr-gcc-list] String in flash

[David Breeze]

This works for me.

static u8  PROGMEM key_test[] = {"Any old string will do here"};

I've read all the manual and header files. I've tried:

   static const char* hex="0123456789abcdef";
   static PGM_P hex="0123456789abcdef";
   static PGM_P hex=(prog_int8_t*)"0123456789abcdef";

but the "0123456789abcdef" string seems to go in the .data
section:

   217                          .data
   218                  .LC0:
   219 0000 3031 3233           .string "0123456789abcdef"
   219      3435 3637
   219      3839 6162
   219      6364 6566
   219      00
   220                          .type   hex, @object
   221                          .size   hex, 2
   222                  hex:
   223 0011 0000                .word   .LC0

These give an error:

   static PGM_P hex =  pgm_read_byte("0123456789abcdef");
   static PGM_P hex =  PSTR("0123456789abcdef");
gives:
   error: braced-group within expression allowed only inside a function
