Hi Tery,
The average_sensor() procedure prodive average
reading of a given analog port (the first parameter
of the function). The result of the sensor value
is then stored a the given variable via the pointer
given to the function via the second paramter.
Example:
void sense_temp (void)
{
int temp_value; /* temp. read from sensor */
/*
* Read the tempt from sensor at analog port
* 0.
*/
average_sensor (0, &temp_value);
if (temp_value > OVER_TEMP) {
sound_alarm();
shut_down();
}
..... other thing ....
}
