Using a AtMega328p from another Arduino device

[doskoi]

Thanks for the useful material, this doc do the same thing in another approach https://docs.arduino.cc/built-in-examples/arduino-isp/ArduinoToBreadboard/

Or from the comments inside the source code

To program
 *  1) Select the following settings under (Tools)
 *      Board->Minicore->Atmega328 
 *      Clock->Internal 8MHz
 *      BOD->BOD 2.7V
 *      EEPROM->EEPROM retained
 *      Compiler LTO->LTO Disabled
 *      Variant->328P / 328PA
 *      Bootloader->No bootloader
 *  2) Set programmer of choice, e.g.'Arduino as ISP (MiniCore)', 'USB ASP', etc, and set correct port.
 *  3) Burn bootloader (to set fuses correctly)
 *  4) Compile and upload

I was upload without set fuse nor use minicore to set internal clock but just sodering chip on this board,
Then I'm using breadboard with DIP 16M external clock attach to XTAL1 and XTAL2 (PIN7, 8), after this I can comminucate with 328p by programmer again.
