[SOLVED] Structure with array of int16 issue |

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
