How to fix the code

[velkov5]

Hello !
I've been trying to control a stepper motor for a long time, but I have a problem with the code. Can you help me with the code please

Arduino - Control the Step Motor with IR remote control

#include < IRremote . h >

//Pin setting
const int EnablePin = 4 ; //Motor enable pin
const int StepPin = 3 ; //Motor PWM pin
const int DirectionPin = 2 ; // Motor direction pin

// Speed
const int FastMove = 200 ;
const int SlowMove = 1000 ;

// Remote control related
int RECV_PIN = 11 ;
IRrecv irrecv ( RECV_PIN );
decode_results results ;

uint16_t irCustomeCode ; //Custom ID (2 bytes)
uint8_t irValue ; // Actual button value
uint8_t irInvertValue ; // the inverted value of the button value

// value of the remote control button to use
const uint8_t IR_BACK_KEY = 0xE0 ;
const uint8_t IR_GO_KEY = 0xA0 ;
const uint8_t IR_REPEAT_KEY = 0xFF ;

const uint8_t NOTHING_KEY = 0 ;
const uint8_t BACK_KEY = 1 ;
const uint8_t GO_KEY = 2 ;

void setup ( )
{
// pin setup
pinMode ( EnablePin , OUTPUT ) ;
pinMode ( StepPin , OUTPUT ) ;
pinMode ( DirectionPin , OUTPUT ) ;

// Motor IC ON
digitalWrite ( EnablePin , LOW ) ;

Serial . begin ( 9600 ) ;

//Start the remote control
irrecv. enableIRIn ( ) ;
}

//Remote control key input function
uint8_t oldIrKey = NOTHING_KEY ;
uint8_t getIRKey ( )
{
uint8_t key = NOTHING_KEY ;
// If there is remote control data
if ( irrecv . Decode ( & results ) ) {
// custom ID and data separation
irCustomeCode = ( results . Value >> 16 ) & 0xFFFF ;
irValue = (results . value >> 8 ) & 0xFF ;
irInvertValue = results . value & 0xFF ;
irrecv . resume ( ) ;

//Check
if remote control data is normal if ( ~ irValue != irInvertValue )
{
// Output to key value monitor
Serial . println ( irValue , HEX ) ;
//If the key is a GO button,
if ( irValue == IR_GO_KEY )
{
key = GO_KEY ;
oldIrKey = key ;
}
//If the key is a BACK button
else if ( irValue == IR_BACK_KEY )
{
key = BACK_KEY ;
oldIrKey = key ;
}
//If the key is still pressed
else if ( irValue == IR_REPEAT_KEY )
{
// Transfer the previous button state
key = oldIrKey ;
}
else
{
//error
oldIrKey = 0 ;
}
}
else
{
//Error
oldIrKey = 0 ;
}
}
return key ;
}

void loop ( )
{
int i ;
//Get remote control button value
uint8_t irKey = getIRKey ( ) ;
//If the button is GO
if ( irKey == GO_KEY )
{
//High state moves clockwise
digitalWrite ( DirectionPin , HIGH ) ;
for ( i = 0 ; i < 50 ; i ++ )
{
//ON 1.8 1/4 move
digitalWrite ( StepPin , HIGH ) ;
//1ms(1000us) wait
delayMicroseconds ( SlowMove ) ;
//OFF 1/4 move of 1.8
digitalWrite ( StepPin , LOW ) ;
//1ms(1000us) wait
delayMicroseconds ( SlowMove ) ;
}
}
//If the button is Back,
else if (irKey == BACK_KEY )
{
//Low state moves counterclockwise
digitalWrite ( DirectionPin , LOW ) ;
for ( i = 0 ; i < 500 ; i ++ )
{
digitalWrite ( StepPin , HIGH ) ;
//0.2ms(200us) wait
delayMicroseconds ( FastMove ) ;
digitalWrite ( StepPin , LOW ) ;
//0.2ms(200us) standby
delayMicroseconds( FastMove ) ;
}
}
}

but I have a problem with the code

But you're not going to tell us what it is?

Please remember to use code tags when posting code.

[groundFungus]

I cannot guess from the video what the problem might be.

What version of the IRremote library are you using? The newest version of the library is not compatible with older code.

Read the how get the most out of this forum sticky to see how to properly post code. Remove useless white space and format the code with the IDE autoformat tool (crtl-t or Tools, Auto Format) before posting code in code tags. Please go back and format the code in the original post and post in code tags.

capitalisation issues ?

 if  ( irrecv[color=red] . D[/color]ecode ( & results ) )  {
