IR remote button controls more than one action

Projects Programming

Hey programmers!
I am programming a remote controlled stepper motor that when i hold the remote button, it keeps moving. I know that when you hold down a button on the remote, it gives off the hex FFFFFFFF. I want to be able to hold down the button so that it can move forward when i press the up button, and backward when i hold down the down button. Sadly i can only make the hex FFFFFFFF have one value. Can anyone help me?

code:


#include <Stepper.h>
#define STEPS 32

int stepsPerRevolution;
 Stepper myStepper(STEPS, 8,9,10,11);

 
int remotePin = 6;
IRrecv IR(remotePin);
decode_results cmd;

void setup() {
  Serial.begin(9600);
  IR.enableIRIn();
}


void loop() {
  if (IR.decode(&cmd)) {

  switch(cmd.value){
 
 case 0xFF629D:
            myStepper.setSpeed(500);
            stepsPerRevolution = 2048;
            myStepper.step(70);
            break;

  case 0xFFFFFFFF:
            myStepper.setSpeed(500);
            stepsPerRevolution = 2048;
            myStepper.step(70);
            break;

   case 0xFFA857:
            myStepper.setSpeed(500);
            stepsPerRevolution = -2048;
            myStepper.step(70);
            break;
  }
 
  IR.resume();
  
  }
}

unsigned long lastCmd;

void loop() {
  if (IR.decode(&cmd)) {
    if (cmd.value != 0xFFFFFFFF)  {
      lastCmd = cmd.value;
    }
  switch(lastCmd ){

Thanks for replying! Can you please explain to me what this code does? and where do i put it in the code?

It repeats the last code sent, if it sees a 0xFFFFFFFFF, which is quite obvious I think.

Thank you! it finally works!

You just had to remember the last command received and reissue it, if the repeat is seen.

Alright. Thanks again! The only trouble i had understanding your code was the unsigned long part. I do not know what that means.

It's a variable big enough to hold the value received,
a normal int would be too small (on standard Arduinos).

Ohhh ok. I get it now. Thank you for your help and cooperation!

@hamsa123 , your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project.
