Error: "expected ';' before '{' token"

Using Arduino Programming Questions
#1

I’m new to Arduino and tried to edit a code I downloaded to make an RC Car with RF 433 modules and a joystick, but it doesn’t work.

This is the code:

#include <VirtualWire.h>
 
const int receive_pin = 11;
 
String message; 
String myString;
 
// para el joystick
int xvalue; 
int yvalue;
int buttonf;
int buttonl;
int xdata; 
int ydata; 
int bfdata;
int bldata;

// para el driver de motores
int BIA = 3;
int AIA = 6;
int BIB = 5;
int AIB = 9;
int velocidadr;
int velocidadi;
int reversar;
int reversai;
// para el led y el buffer
int led;
int buf;
int ledp;
 
void setup()
{
  delay(1000);
  pinMode(AIA, OUTPUT);
  pinMode(AIB, OUTPUT);
  pinMode(BIA, OUTPUT);
  pinMode(BIB, OUTPUT);
  pinMode(buf, INPUT);
  pinMode(ledp, INPUT);
  
  analogWrite(AIA, 0);
  analogWrite(AIB, 0);
  analogWrite(BIA, 0);
  analogWrite(BIB, 0);
  delay(1000);
 
 
    // iniciar módulo rf
 
    vw_set_rx_pin(receive_pin);
 
    vw_set_ptt_inverted(true);
    vw_setup(2000);
 
    vw_rx_start();
 
}
 
void loop()
{
    uint8_t buf[VW_MAX_MESSAGE_LEN];
    uint8_t buflen = VW_MAX_MESSAGE_LEN;
 
    if (vw_get_message(buf, &buflen))
    {
    int i;
    
    for (i = 0; i < buflen; i++)
    {
        char c = (buf[i]);
            message = message + c; // hacer un mensaje con los carácteres recibidos      
    }
  myString = message; 
 
String l = getValue(myString, ',', 0); // xvalue
String m = getValue(myString, ',', 1); // yvalue
String n = getValue(myString, ',', 2); // buttonf
String k = getValue(myString, ',', 3); // buttonl
 
xdata = l.toInt();
ydata = m.toInt();
bfdata = n.toInt();
bldata = k.toInt();
 
 // parado

 if ( ((xdata >= 480)&&(xdata <= 510)) && ( (ydata>=480) && (ydata<=510) ) )
 {
  velocidadr = 0;
  velocidadi = 0;
 }
 
 // si está apretado el botón del buffer
 
 if (bfdata == 0)
 {
  digitalWrite{buf, HIGH};
 }else if (bfdata == 1)
  {
    digitalWrite(buf, LOW);
  }
  
 // si está apretado el botón del led

  if (led == 1)
  {
    digitalWrite(ledp, HIGH);
  }else if (led == 0)
    {
      digitalWrite(ledp, LOW);
    }
  
  if (bldata == 0)
  {
    if (led == 0)
      {
      led = 1;
      } else if (led == 1)
        {
          led = 0;
        }
  }
  
  // adelante
 
 if ((xdata > 510)&&(xdata <= 1023))
 {
   int xmapped = map(xmapped, xdata, 1023, 255,0);
   velocidadr = xmapped;
   velocidadi = xmapped;
   reversar = 0;
   reversai = 0;
 }

  // atras

 if ((xdata >= 0)&&(xdata < 480));
 {

   velocidadr = 0;
   velocidadi = 0;
   reversar = xmapped;
   reversai = xmapped;
 }

 // derecha
 if ((ydata> 510)&&(ydata <= 1023));
 {
   int ymapped = map(ymapped, ydata, 1023, 255,0);
   velocidadr = velocidadr- ymapped;
   reversar = reversar - ymapped;
 }
 
  // izquierda
 if ((ydata >= 0)&&(ydata <= 479));
 {
   int ymapped = map(ymapped, ydata, 479, 255,0);
   velocidadi = velocidadi - ymapped;
   reversai = reversai - ymapped;
 }

 // eliminar negativos reversa
 
 if (reversai < 0)
 {
   reversai = 0;
 }

 {
   reversar = 0;
 }

 // eliminar negativos velocidad

 if (velocidadi < 0)
 {

 }

 }

int velocidadt = velocidadr + velocidadi;
int reversat = reversar + reversai;

 // comenzar movimniento

 // en reversa
 if (reversat > 0)
 {
  analogWrite(AIA, reversai);
  analogWrite(AIB, 0);
  analogWrite(BIA, reversar);
  analogWrite(BIB, 0);
 }else if (velocidadt > 0)
  {

  } else
    {
      analogWrite(AIA, 0);
      analogWrite(AIB, 0);
      analogWrite(BIA, 0);
      analogWrite(BIB, 0);
    }


 
     message = "";
    }
    
 
}
 
 
String getValue(String data, char separator, int index)
{
    int found = 0;
    int strIndex[] = { 0, -1 };
    int maxIndex = data.length() - 1;
 
    for (int i = 0; i <= maxIndex && found <= index; i++) {
        if (data.charAt(i) == separator || i == maxIndex) {
            found++;
            strIndex[0] = strIndex[1] + 1;
            strIndex[1] = (i == maxIndex) ? i+1 : i;
        }
    }
    return found > index ? data.substring(strIndex[0], strIndex[1]) : "";
}

The error is:

error: expected ';' before '{' token

And many warnings

#2 
      digitalWrite{buf, HIGH};

should be

      digitalWrite(buf, HIGH);
#3

if ((xdata >= 0)&&(xdata < 480)); <———<<<< get rid of the ;

And there are many more too.

#4

UKHeliBob:

      digitalWrite{buf, HIGH};

should be

      digitalWrite(buf, HIGH);

Thank you so much! It works!

#5

It works!

It might compile but does it work ?

#6
