| Feb 11, 2022 at 14:20 | comment | added | Edgar Bonet | Yes, the first tutorial uses “Arduino as ISP” for burning a bootloader, then the USB-to-serial converter of the Arduino to burn the actual sketch through the bootloader. What I am saying is that you can forgo the bootloader and use “Arduino as ISP” (or any other ISP programmer, for that matter) to burn the actual sketch. | |
| Feb 11, 2022 at 12:50 | comment | added | Pere | Thanks a lot for the comments; they are really helpul. I edited the question acording to the busybee notes and added the missing link to the 2nd tutorial I mentioned. @EdgarBonet, is my link to the 1st tutorial an example of Arduino as ISP? | |

Removed the "source" from "source code" because it's compiled as noted by a user

| Feb 10, 2022 at 14:25 | comment | added | Majenko | The idea of removing the existing MCU is either so you can replace it with yours, or to use the Arduino purely as a USB to UART adapter. For the latter just connect RESET to GND and it will disable the onboard MCU - it will be just like you have removed it. | |
| Feb 10, 2022 at 8:24 | comment | added | Edgar Bonet | 1. You don't need to put a bootloader on the spare Atmega328P. The bootloader is a nice convenience for development, as it allows you to upload the program through the serial port. For the final product, if you are OK with using an ISP programmer (e.g. “Arduino as ISP”), the bootloader is not needed. Ditching it will make your sketch start way faster. 2. You don't need to remove the microcontroller from the Uno. | |
| Feb 10, 2022 at 7:13 | comment | added | the busybee | OT, you don't upload source code. You upload the executable that is compiled and linked from your source code. | |
| Feb 10, 2022 at 0:03 | comment | added | chrisl | You don't need to remove the microcontroller from the board. Just keep it in the reset state by connecting the reset pin to ground. That prevents the microcontroller to disturb the communication with the external atmega | |
