The first step ： How to burn ATmega16U2 chip?
1.Open AVRDUDESS software,Programmer-choose USBtiny simple USB Programmer,pORT-choose USB,write 19200 in the Bard rate;
2.We can detect the following chips,the computer detects that the chip is ATmega16U2,the signature is 1E9489;
3.Then read the Fuses and Lock bits,we import the Flash file into the softeare,This file is saved under the firmwares of the Arduino file,After opening the file,we change the Fuses to the following settings:
Fuse bit Low bit 0XFF
High bit is 0XD9
Extended bit is 0XF4
Lock bits is OXCF
After setting, we need to check Set Fuse and See lock；
And then ,we can Programm,
Second step： How to burn the ATmega328p chip?
We need to burn the bootloaderof ATmega328P-PU.We open the Arduino IDE,we click Brun bootloader.
Finally, we use an LED light to check whether the burning is successful, we can see that the LED light is flashing, indicating that we have successfully burned
