| how to pass "led" through function |
 Posted: Tue May 11, 2004 9:44 am |

|
#define led1 PIN_A1
#define led1 PIN_A2
#define led1 PIN_A3
#define tension_maxi_touche_0 34
void calcul (ledx,int16 tension_maxi_touche_x,int16 tension_mini_touche_x,int1 ledy,int1 ledz)
{.....................
}
void main void
{
calcul(led1,tension_maxi_touche_0,tension_mini_touche_0,led2,led3);
}
so how can i set led in the function

Change
ledx
to this
Int1 ledx
Also you can not define a constant (led1) to have several values |

Try this:
| Code: |
void calcul(int8 ledx)
{
switch(ledx)
{
CASE 0:
output_high(PIN_A1);
break;
CASE 1:
output_high(PIN_A2);
break;
CASE 2:
output_high(PIN_A3);
break;
default:
break;
}
}
void main void
{
int8 led;
calcul(led);
while(1)
{
;
}
}
|
Just pass the correct number for the LED you want turned on. |

i've to pass more than one led into function like this code:
