Serial connection between arduino and labview

Projects Programming

hi im new at this, im looking for help....... because im stuck in this, basically what i need to do is send from labview a serial message to the arduino and turn On and Off LEDS, i have already made it work but just sending one character for example

data = serial.read()
if (data =="d") {
digitalWrite( 8, HIGH)
}

now what im trying to do .. is send a whole string of characters and compare it like this for example :

String readString;

void setup() {
  Serial.begin(9600);	// opens serial port, sets data rate to 9600 
  for (int var=2; var<=8; ++var)
      {
      pinMode(var,OUTPUT);
      }
      
      for (int var2=9; var2<=13; ++var2){
        pinMode(var2,INPUT);
}
}

void loop() {
 

  while (Serial.available()) {
    delay(100);
    if (Serial.available() >0) {
      char c = Serial.read();
      readString = c;
      
    }
    
         if(readString=="1000000"){
    digitalWrite(2, HIGH);
    digitalWrite(3,LOW);
    digitalWrite(4,LOW);
    digitalWrite(5,LOW);
    digitalWrite(6,LOW);
    digitalWrite(7,LOW);
    digitalWrite(8,LOW);
    
  }

my problem is that is not working,i dont know how to get the whole string from the serial and compare it

please really need to understand why i cant make it work , ill be glad if someone helps me

Put each { on its own line. Use Tools + Auto format. I think it will then be obvious what your problem is. If not, post the cleaned up code.

hello
I don't have an answer for you but this month the ELEKTOR magazine have an article approaching that. Anyway if you are interested look for ithttp://www.elektor.com/ or just post the code and the community will help you for sure
