[Suggestion] CH340 and FT232 programmers

[Monniasza]

Hi. I'm thinking about reflashing the bootloader on an Arduino Nano clone. It uses CH340 interface chip, and I also have the FT232 programmer board. Currently, no programmer option works with the clone. I'd be grateful if you add support for the programmers.

FT232 and CH340 are just USB to UART chips. They will only work for uploading new programs as long as the microcontroller has a bootloader present. All you do is select the correct COM port that the CH340 or FT232 represents on your computer

Do I have to have separate Arduino as a programmer?

[MCUdude]

Either that, or a dedicated programmer, such as a USBasp or a USBtinyISP, which is what I'd recommend, since using "Arduino as ISP" is a bit fiddly and is usually unreliable due to its DIY nature

[Monniasza]

My USBasp isn't recognized as a serial device. By the way, I use Linux Mint and Arduino IDE on Flatpak.

[MCUdude]

The USBasp is not a serial device, so it will not show up as a serial device.

You'll have to select the appropriate settings and hit "Burn bootloader" after you've selected "USBasp" or "USBasp slow" under the "Programmers" menu.
