I have 3 Arduino’s: an Uno, a Mega 2560 and a Micro. I few days ago i tried to load the bootloader on some Atmega328 chips that i bought using the Arduino ISP sketch and the Mega 2560 as ISP programmer. I messed something up and it didn’t work. But that’s not the point of this topic! After my fail…i tried uploading some simple code…like blinking a LED or only sending some data from the Arduino to the computer via Serial and it won’t work in the Mega 2560 anymore:( The odd thing is that nor the Uno works anymore…and the computer won’t even see the Micro anymore as a COM connection:( I did the Loop-Back Test on both Uno and Mega…and everything was fine. If i write digitalWrite(LED,HIGH) in the int main() it even turns the LED on but if i try blinking it in the void loop or with a while(true) in the int main() it won’t work. I just can’t understand what happened. The Uno had nothing to do with my bootloader fail and it is brand new from Arduino!
Please help me! I was working on a project and now i can’t do nothing!
