Hello,

The following program stores the string "This text..." in Flash EPROM.

It is copied into the RAM based string YourData[].

What is required is the word "const" ahead of the declaration.

#include <hidef.h> /* for EnableInterrupts macro */
#include "derivative.h" /* include peripheral declarations */

char unsigned x;

char YourData[10];

const unsigned char MyData[] = {"This text is stored in Flash EPROM"};

void main(void) {
 

  EnableInterrupts; /* enable interrupts */

  for(; {

  for ( x = 0;x< 10;x++) YourData[x] = MyData[x];
    __RESET_WATCHDOG(); /* feeds the dog */
  } /* loop forever */
}

Was this what you were looking for?

Regards,

Ake
