i tried to upload a program code to my arduino just now, but i close the arduino software when it is still uploading.
after that i reopen the arduino software and try to upload a program code and now the problem come:
it show: avrdude: stk500_getsync(): not in sync: resp=0x30 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
pls help ! urgent! before i(so stupid) close the software during the process of uploading, everything is OK! but now
using arduino diecimila and windows vista home premium and arduino-0011 Alpha
Well, starting with the basics, have you tried reseting your arduino or unplugging it from power, waiting several minutes, and plugging it back in for another try?
I get that error everytime I accidentally hit upload before I hit reset on my sanguino or if I wait too long after it first powers up. In my case it just means my bootloader only waits 3 seconds for communication from my laptop. If it doesn't receive anything it starts running my sketch that's already on it and I have to reset it to upload anything.
Hola a todos! Soy nuevo por acá y quería compartir algo.
Ayer en mis primeras experiencia con arduino (NG) no podía subir el programa a la placa, me daba el siguiente error:
avrdude: stk500_getsync(): not in sync: resp=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
Y busqué por el foro -incluso en su versión italiana!- pero no había respuestas claras, solamente algunas pistas.
