I have a program that makes some tasks and it checks for infrared signals.all i want is every time it checks for IR signals i want the scetch to start from begining. I tried with goto but it only works inside their void
Since you want the 3 tasks to do something different, (and presumably if you notice IR data after task_1 you want to skip task_2), you might want something like this: (using flags)
byte incoming_IR_data;
boolean IR_received; // Flag for knowing if you have to do something different when IR information has been received. Should initialize to 0 (which ==FALSE)
void setup() {
pinMode(13, OUTPUT);
}
void loop() {
if (IR_received) //
{
// code to handle IR stuff if needed. Otherwise unwrap the following line out of the if statement.
IR_received = FALSE; // (Re)set the received flag
}
task_0();
task_1();
task_2();
}
void task_0()
{
// don't need to check IR_received here because we haven't checked IR communication since we last reset the flag
//some code here
check_IR();
}
void task_1()
{
if (!IR_received) // if IR_received == FALSE
{
return; // return from the function w/o doing anything
}
//some code here
check_IR();
}
void task_2()
{
if (!IR_received) // if IR_received == FALSE
{
return; // return from the function w/o doing anything
}
//some code here
check_IR();
}
void check_IR()
{
//Some code that checks IR and stores data from Infrared to incoming_IR_data variable
if (incoming_IR_data==12524)
{
IR_received == TRUE; // Set the flag that basically neuters the other functions.
}
}
Now, I'm not sure if this is what you really want, but I think it should do what you asked.
