Hi,
After spending more than one day to create an array of struct I have
come to this code:
struct Lamp {
uint8_t highAddress [9] ;
uint8_t lowAddress [9] ;
uint8_t onoff ;
uint8_t active ;
uint8_t power;
uint8_t brightness ;
uint8_t temperatures ;
uint8_t faultCount ;
} ;
struct Lamp lamps [10];
void init () {
struct Lamp lamp0 = {" 0013A200 ", " 4094500D " , 0 , 1 , 0 , 0, 0 , 0} ;
struct Lamp lamp1 = {" 0013A200 ", " 40B12530 " , 0 , 1 , 0 , 0, 0 , 0} ;
struct Lamp lamp2 = {" 11111111 ", " 22222222 ", 0 , 0, 0 , 0, 0, 0 };
struct Lamp lamp3 = {" 33333333 ", " 44444444 ", 0 , 0, 0 , 0, 0, 0 };
struct Lamp lamp4 = {" 55555555 ", " 66666666 ", 0 , 0, 0 , 0, 0, 0 };
struct Lamp lamp5 = {" 77777777 ", " 88888888 ", 0 , 0, 0, 0 , 0, 0 };
struct Lamp lamp6 = {" 99999999 ", " 00000000 ", 0 , 0, 0, 0 , 0, 0 };
struct Lamp lamp7 = {" AAAAAAAA ", " BBBBBBBB ", 0 , 0, 0, 0 , 0, 0 };
struct Lamp lamp8 = {" CCCCCCCC ," " DDDDDDDD ", 0 , 0, 0, 0 , 0, 0 };
struct Lamp lamp9 = {" EEEEEEEE ", " FFFFFFFF ", 0 , 0, 0, 0 , 0, 0 };
lamps [0] = lamp0 ;
lamps [1] = lamp1 ;
lamps [2] = lamp2;
lamps [3] = lamp3 ;
lamps [4] = lamp4 ;
lamps [5] = lamp5 ;
lamps [6] = lamp6 ;
lamps [7] = lamp7 ;
lamps [8] = lamp8 ;
lamps [9] = lamp9 ;
}
it compiles without errors ( and it may be that it works!) but it is
certainly wrong because it consumes twice the memory required (once for
the array [ 10] and another for 10 lamps).
The question is: how can I initialize the array without defining first
ten lamps individually ?
Thank you very much .
