Hi all,

I try a simple program with array:

#ifdef __USE_CMSIS
#include "LPC17xx.h"
#endif

#include <cr_section_macros.h>
#include <NXP/crp.h>

__CRP const unsigned int CRP_WORD = CRP_NO_CRP ;

[B]uint8_t pole[5];[/B]

int main(void) {

// TODO: insert code here

[B]pole = {1,2,3,4,5}; // [COLOR=Red][B]<- IS IT CORRECT?[/B][/COLOR][/B]

// Enter an infinite loop, just incrementing a counter
volatile static int i = 0 ;
while(1) {
i++ ;
}
return 0 ;
}

When I start DEBUG so it write me:

Quote:

make: Nothing to be done for `all'.

What do I do wrong?

uint8_t pole[5]  = {1,2,3,4,5};

I know this way, but I want to save data to "pole" in MAIN(). Is it possible?

Everything is possible

uint8_t pole[5];

int main(void) {
    
    // TODO: insert code here

    // Enter an infinite loop, just incrementing a counter
    volatile static int i = 0 ;
  [COLOR=Red]  memcpy(&pole[0],(uint8_t*)"\001\002\003\004\005",5);[/COLOR]
    while(1) {
        i++ ;
    }
    return 0 ;
}

The {1,2,...} are array [I]initialisers[/I], and can only be used in the [I]declaration[/I].

use

 uint8 pole[5] = {1,2,3,4,5};

and lose the 'pole =' in main.

[FONT=Comic Sans MS][SIZE=1]My mistake (sorry). I must have read the first post and skipped to the end.
I hate it when I assume and it bites me!

While the memcpy() is probably as close as you'll get I have a sneaking suspicion that the slightly obvious

pole[0] = 1;
pole[1] = 2;
pole[2] = 3;
pole[3] = 4;
pole[4] = 5;

May actually be the "tightest" solution on this occasion. Either that or:

for (uint8_t i=0; i<5; i++) pole = i+1;

Though that only works because of the pattern to the example data.
