I was trying my little sketch when Arduino ide crash... So i launch again the ide but now i can't upload file on board! If i click on tools the program slows and after 20 sec appears: Port already in use and sometimes also appears port not found!
What could have happened?

Have you restarted your computer (is it windows or mac?)? Have you reinstalled the drivers? Have you got the current IDE(don't know what version you havbe)? Have you Re-Downloaded and extracted the IDE?
We need more info - what have you tried, what do you mean by 'I was trying my little sketch...', were you just typing, opening the sketch, or uploading.

I've restarted yes. I use Ubuntu.. I have delete the folder and re-extract it. I compile the sketch, but when i try to upload it on arduino i have the problem!

The sketch that initially works is:

Code:

void setup(){
  Serial.begin(9600);
  pinMode(13, OUTPUT);
}

void loop(){
 
    int inByte = Serial.read() - ('0');
    if(inByte == 1)
      digitalWrite(13, HIGH);
    if(inByte == 0)
      digitalWrite(13, LOW);
  }


}

I think that my problem is similar to  http://stackoverflow.com/questions/5290428/how-to-reset-an-arduino-board

[Reply #5 on:]

disconnect arduino from everything (including PC).
Press RESET and reconnect usb - keep RESET pressed
hit upload in IDE
when sketch size comes up release RESET.

See if that helps


Drew.

The post you have provided is for arduino uno - not the normal arduino.

I've Arduino UNO.  Sorry i forget to say it And sorry for my bad english 

[Reply #8 on:]

No problem - have you tried the above?

[Reply #9 on:]

Yes, the result:

Code:

avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x00

avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x00
avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x00
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
