Re: [avr-gcc-list] Using flash memory for storing large look up tables

[Royce Pereira]

Hi,

There was an error in my example, corrected below!
//--------------------
unsigned todayssunset;

const unsigned sunrise[2][4] PROGMEM ={         1,2,3,4,        6,7,8,9  };

> > > > > > > todayssunset= pgm_read_byte(&sunrise[x][y]);

Sorry, thats:

todayssunset= pgm_read_word(&sunrise[x][y]);

//-----------------
All this and more is covered in the AVR libc manual & FAQ.
