Damaged ATmega 328P
QCX T / R 18 MHz type was made, but it does not work.
Only square boxes are out in the first row.
Troubleshooting saw the same phenomenon, ATmega 328P is not inserted or it is not working properly. Is the IC pin bent? But none of them were applicable.
Finally there is a possibility that ATmega 328P is broken. There is and download data from this failed ATmega 328P. (It was possible to some extent, but the size of eep is too small? Size=2.891KB)
Uploading the downloaded data to the new ATmega 328P launched the radio.
Unfortunately, I found out that it did not become a setting screen.
Pressing the button on the left side for a long time on the setting
screen returns to the original state.
It seems that eep data is broken. Is this data only?
I think that it is probably because the original ATmega 328P data could not be read to the end.
