I hope i am in the correct forum with this post. I have got a problem with my Arduino UNO. I have sucsessfully installed the drivers and the compiler, but when i tried to launch a example program it is uploading, but when it has finished it says :"avrdude: stk500_getsync(): not in sync: resp=0xc2"
I have also googled this problem, but i found no help.
If u need some more information pls tell me and thx for your answers.
There is something wrong between the computer and the Arduino board. Or the Arduino board is broken.
Is it an official Arduino board, or a clone from Ebay ?
You could try an other usb port, or an other usb cable or even on an other computer.
Did you use the newest compiler ? Version 1.0.5 or 1.5.7 BETA ?
And did you use the drivers that are included with that ?
You can open the Device Manager in Windows, and try to find the driver. Perhaps it is the wrong driver, or try to re-install it.
It is not my board i just got it from a friend, but i gues it is a official one.
I have tried different usb ports and i also tried it on my pc.
There appeared nearly the same message the only different was 0x00 instead of 0xc2 at the end.
I asked my friend about that but he knew not much he only told me i have to programm it with avr studio, because the arduino has got its own programming chip.
He also said if i want to programm with anoither compiler i'd have to buy a new one resp. a new chip.
He read that somewhere, but i can not understand that.
Why should it matter which compiler is used ?
Or do i get something wrong there ?
I was using Version 1.0.5
btw thank u for your fast reply
There are more clones than official Arduino boards. When you guess it is an official one, then I guess it is a clone :~
There is a chip on the Arduino Uno board for usb-to-serial. When that chip is broken, the board can still be used with a programmer.
For the programmer is a 6 pin connector (2x3rows), it is called the ICSP header.
That would mean the board is broken. Using a programmer is for advanced users.
Or the microcontroller on the Arduino Uno board has been replaced. It should be an ATmega328p, can you check that with a magnifier ?
When you start with Arduino, you should start with a good Arduino Uno board. Arduino is all about getting started fast: connect via usb; install usb drivers; start software; choose example; upload; ready.
Version 1.0.5 is good.
The Arduino Uno board is the easiest board to start with. Even when the usb-to-serial chip is broken, the Arduino IDE (the Arduino software on the computer) can also use a programmer and program the microcontroller via the ICSP header.
However, when the microcontroller has been replaced, it might not be supported by Arduino. Perhaps that is why your friend mentioned another compiler or another chip.
When you like to program and want to get to know Arduino, buy a new board (if your board is broken or has the wrong microcontroller).
I bought a cheap clone Arduino Uno on Ebay for 7 dollars (inclusive shipping), just to see if was any good. I have it running now next to me without problem. But it has the CH340 chipset, so I needed a Windows driver from wch-ic.com
My local Arduino supplier sell the official Arduino Uno for 24 dollars (exclusive shipping).
