The goal of this library is to provide a solution for tasks that require some kind of interval pattern, while barely interfearing with the entire runtime time process ulike delays. This is done by Protothreading using time stamps that get checked in an regulare pattern, being the interval. For simple time stamp interreaction, use the time_stamp class that is packed with various useful functions for time_stamp reading and writing. To build a interval, create an instance of definable_interval and refference onInterval to your desired function. This function is then executed on every interval. To start a interval, execute the interval() member function inside of your desired loop. The function will not delay runtime, instead it will skip until the next interval.
Including the library :
#include <Interval.h>Defining a interval with a length of 1 second that executes function f:
void f() {
...
}
definable_interval interval(1000, &f):Interval that prints "Hello" to the serial output every second while printing the state of pin D3 D4 D5 and D6. No delays involved!
#include <Interval.h>
/* Will be called on Interval */
void hello() {
Serial.println("Hello");
}
/* Interval that print hello every second */
definable_interval hello_interval(1000, &hello);
void setup() {
for (int i = 0; i <= 6; i++) {
pinMode(i, INPUT);
}
Serial.begin(9600);
}
void loop() {
/* Check and execute interval */
hello_interval.interval();
/* No delay */
/* Print Pin states */
for (int i =0; i <= 6; i++) {
Serial.println(digitalRead(i);
}
}
