I have a ATmega328p-pu. I programmed it using the Minimal Circuit of this tutorial.
I burned the boatloader on the microcontroler. I uploaded a couple of sketches using the way of uploading the bootloader(because i have a arduino uno smd). First worked fine but then....it stopped working i got this error:
avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.
I double checked the connections. Nothing wrong. I looked on forums but couldn't find it. I tried to find out how to use that -F thing. But couldn't find that as wel.
Can anyboady tell me how to solve this problem? Is there any way I can find out if the chip is damaged? Or can i maybe reset it to factory settings Or erase the eeprom memory?
