[SOLVED] Structure with array of int16 issue
PostPosted: Mon Jun 15, 2020 3:50 am     Reply with quote
hello,

I'm working on a project and want to use a structure which contain an array of int16, but I have wird result :(

exemple of code :
Code:
#include <18F66J94.h>
#device ADC=12

#FUSES NOWDT                    //No Watch Dog Timer

#use delay(clock=64MHz,crystal=16MHz,USB_FULL)

#include <usb_cdc.h>

typedef struct {
   int   puissances [10];
   int16 profondeurs[10];
} exerciceAl;

void affichage(exerciceAl exer_loc){
   int i;
   if(usb_cdc_carrier.dte_present){
      printf(usb_cdc_putc,"puissances           :");
      for(i=0;i<10;i++)
         printf(usb_cdc_putc," %2u",exer_loc.puissances[i]);
      printf(usb_cdc_putc,"\r\nprofondeurs G         :");
      for(i=0;i<10;i++)
         printf(usb_cdc_putc," %2lu",exer_loc.profondeurs[i]);
      printf(usb_cdc_putc,"\r\n");
   }
                                 
}

void main()
{
   setup_lcd(LCD_DISABLED);
   setup_adc_ports(sAN0 | sAN1 | sAN7, VSS_VDD);
   setup_adc(ADC_CLOCK_INTERNAL | ADC_TAD_MUL_0);
   
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_64);      //262 ms overflow,  resolution 4us
   setup_timer_1(T1_INTERNAL|T1_DIV_BY_8);        //32,7 ms overflow, resolution 0,5us
   
   disable_interrupts(INT_TIMER0);
   disable_interrupts(INT_TIMER1);
   disable_interrupts(INT_EXT);
   disable_interrupts(INT_RDA);
   enable_interrupts(GLOBAL);
   
   usb_init();
   usb_task();
   
   int connectedUSB = 0;
   
   exerciceAl exer_testAL =  {5,5,5,5,5,5,5,5,5,5,
   200,200,200,200,200,200,200,200,200,200};
   
   while(true){
      usb_task();
      if(usb_cdc_carrier.dte_present){
         if(connectedUSB == 0){
            connectedUSB = 1;
            printf(usb_cdc_putc,"Test\r\n");
            affichage(exer_testAL);
         }
      }
   }
}


I got :
Quote:
Test :
puissances : 5 5 5 5 5 5 5 5 5 5
profondeurs G : 0 0 0 0 0 0 0 0 0 0


but I expected :
Quote:
est :
puissances : 5 5 5 5 5 5 5 5 5 5
profondeurs G : 200 200 200 200 200 200 200 200 200 200


what is wrong ???

thanks for your help

regards

same result if I add
Code:
for(int i=0;i<10;i++)
   exer_testAL.profondeurs[i] = 100;

just before the "while" loop

others will KNOW but I'm guessing you really need for i=10 to 19 to get the int16 elements from the array ?

Brackets. You are sending all the elements to the first array (so the second
lot gets thrown away):
Code:

exerciceAl exer_testAL =  {{5,5,5,5,5,5,5,5,5,5},
  {200,200,200,200,200,200,200,200,200,200}};

Note the extra two brackets, and the change in the comma position.

A single structure, containing an array of ten elements, then a second
array of ten elements.

I change it

I found the issue :
Code:
printf(usb_cdc_putc," %2lu",exer_loc.profondeurs[i]);

changing it by
Code:
printf(usb_cdc_putc," %lu",exer_loc.profondeurs[i]);

seems to solve the issue

thanks for your help

regards
