| Best way to sort?? |

Help minds gone blank just can't think this one through at the moment.
I have an array with 10 readings from the 10 ADC pins stored in it, I need to find which one is the lowest value what's the easiest way to do this without endless if statements.
thanks

Try this ...
| Code: | int8 lowestValueIndex;
uint16 lowestValue;
lowestValue = 0xFFFF; // max value for a uint16
lowestValueIndex = -1;
for (i=0; i<10; i++) {
if (myValues[i] < lowestValue) {
lowestValue = myValues[i];
lowestValueIndex = i;
}
}
|
lowestValue should use the same variable type as myValues[].
Although you should have been able to figure this one out !!!

Depends how old your compiler is, but if it is recent, look at 'Qsort' in the manual.

Thanks guys, I now I should have been able to do this but we have builders in our building at the moment and they are cutting a wall with a cutting disk so it's a little difficult to concentrate.
