Syntax
int RCTIME(int pin, int state ) ;
Description
Measure the time which pin remains at
state, returning the value to variable.
The length of time is
measured in microseconds(us). The minimum time measured is 1 microseconds.
If
pin is not at level when the function is called variable is
set to 1.
If pin remains at level longer than 1 second
variable is set to 0.
Example
printf("\n check RCTIME into a 700ohm
0.1uF drive on 14, sense on 13\n");
OUTPUT
(14);
// while(1) {HIGH(14);WAIT(1);LOW(14);WAIT(1);} //
scope loop
HIGH
(14);
printf("high to low
");
WAIT(10); // make sure line is
high
LOW(14);
printf("%d
microseconds, high to low ",RCTIME (13,
1));
WAIT(10); // make sure line is
low
HIGH
(14);
printf("%d microseconds, low to high\n",
(RCTIME (13, 0));
check RCTIME into a 700ohm 0.1uF drive on 14, sense on
13
high to low 89 microseconds, high to low 56 microseconds, low to
high
