How can I do multiple tasks in arduino without using the function delay()
and that each task is executed during a certain period and the tasks can run in parallel.
void setup() {
//TODO: ...
}
void loop() {
task1();
delay (...);
task2();
delay (...);
...
taskN();
delay (...);
}
I was consulting in books and I found this solution that works perfectly for me
void setup() {
//TODO: ...
}
void loop() {
task1();
task2();
task3();
}
void task1() {
//{period}: Periodo de Tiempo en el cual se va a ejecutar esta tarea
unsigned long period=200; //En Milisegundos
static unsigned long previousMillis=0;
if((millis()-previousMillis)>period){
// ---------------------------------
// TODO:
// Codigo de la Tarea
// ...
// ---------------------------------
previousMillis += period;
}
}
void task2() {
//{period}: Periodo de Tiempo en el cual se va a ejecutar esta tarea
unsigned long period=500; //En Milisegundos
static unsigned long previousMillis=0;
if((millis()-previousMillis)>period){
// ---------------------------------
// TODO:
// Codigo de la Tarea
// ...
// ---------------------------------
previousMillis += period;
}
}
void task3() {
//{period}: Periodo de Tiempo en el cual se va a ejecutar esta tarea
unsigned long period=1000; //En Milisegundos
static unsigned long previousMillis=0;
if((millis()-previousMillis)>period){
// ---------------------------------
// TODO:
// Codigo de la Tarea
// ...
// ---------------------------------
previousMillis += period;
}
}
Each of the tasks has a variable period that indicates the period in which this task will be executed this period is in Milliseconds .
there is another variable estatica called previousMillis which is what will act as a counter for the task to be executed in the period described.
