Having problem on function decleration

Projects Programming

Hi everybody,

I am having troble with my code.

I built some functions on my code and called them on void loop() function.

sketch_jan01a:7: error: variable or field 'forward' declared void
sketch_jan01a:8: error: variable or field 'backward' declared void
sketch_jan01a:9: error: variable or field 'forwardturnright' declared void
sketch_jan01a:10: error: variable or field 'forwardturnleft' declared void
sketch_jan01a:11: error: variable or field 'backwardturnright' declared void
sketch_jan01a:12: error: variable or field 'backwardturningleft' declared void
sketch_jan01a.ino: In function 'void loop()':
sketch_jan01a.ino: At global scope:
sketch_jan01a:54: error: variable or field 'forward' declared void
sketch_jan01a:66: error: variable or field 'backward' declared void
sketch_jan01a:77: error: variable or field 'forwardturnright' declared void
sketch_jan01a:88: error: variable or field 'forwardturnleft' declared void
sketch_jan01a:99: error: variable or field 'backwardturnright' declared void
sketch_jan01a:110: error: variable or field 'backwardturningleft' declared void

the functions are similiar

which is looks like;

void backwardturningleft(int PWM1VALUE,int PWM2VALUE)
{
digitalWrite(RPWM1,LOW);
analogWrite(LPWM1,PWM1VALUE);
digitalWrite(RPWM2,LOW);
analogWrite(LPWM2,PWM2VALUE);

}

Post your code.
Use code tags.

The whole code is;

///////////////////////////////////-------------------------------PWM PIN CONFIGURATION---------------------------///////////////////////////////////////////
const int LPWM1 = 7; 
const int enL1 = 22; 
const int LPWM2 = 8;
const int enL2 =26; 


const int RPWM1 = 7; 
const int enR1 = 24; 
const int RPWM2 = 8;
const int enR2 = 28; 

///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////



void setup()
{
  PwmPinSetup();
}

void loop() 
{
  forward(157);
  delay(10000);
  backward(157);
  delay(10000);  
}
///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////
void PwmPinSetup()
{

  pinMode(enL2, OUTPUT);

  pinMode(enR2, OUTPUT);
  

  digitalWrite(enL1, HIGH);
  digitalWrite(enL2, HIGH);
  digitalWrite(enR1, HIGH);
  digitalWrite(enR2, HIGH);
}

///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////

void forward(int PWM1VALUE,int PWM2VALUE)
  {
    digitalWrite(LPWM1, LOW);
    analogWrite(RPWM1,PWM1VALUE); //pwm value
    digitalWrite(LPWM2, LOW);
    analogWrite(RPWM2,PWM2VALUE);
    

  }

///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////

void backward(int PWM1VALUE,int PWM2VALUE)
  {
    analogWrite(LPWM1, PWM1VALUE);
    digitalWrite(RPWM1,LOW);
    analogWrite(LPWM2, PWM2VALUE);
    digitalWrite(RPWM2,LOW);

  }

///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////

void forwardturnright(int PWM1VALUE,int PWM2VALUE)
{
  analogWrite(RPWM1, PWM1VALUE);
  digitalWrite(LPWM1, LOW);
  analogWrite(RPWM2, PWM2VALUE);
  digitalWrite(LPWM2, LOW);

}

///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////

void forwardturnleft(int PWM1VALUE,int PWM2VALUE)
{

  digitalWrite(LPWM1, LOW);

}

///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////

{

}

///////////////////////////////////------------------------------***********************--------------------------///////////////////////////////////////////

{
  digitalWrite(RPWM1,LOW);
  analogWrite(LPWM1,PWM1VALUE);

  analogWrite(LPWM2,PWM2VALUE);

}

I got other error's

sketch_jan01c.ino: In function 'void loop()':
sketch_jan01c:6: error: too few arguments to function 'void forward(int, int)'
sketch_jan01c:24: error: at this point in file
sketch_jan01c:7: error: too few arguments to function 'void backward(int, int)'
sketch_jan01c:26: error: at this point in file

Think you have to rewrite part of your code to fix this first.

Thanks I solved the problem with writing parts again.
