I have an atmega328p-au
I also have a USBAsp programmer
I need to flash this microcontroller, I have never done that!
1) I downloaded and installed the drivers for the programmer .. I took them from here.
2) AVRDUDE PROG 3.3 is available.
I found a wiring diagram on the Internet, but I don’t know if it will work or not.

And now I think if I order an adapter for the programmer and connect the microcontroller as in the diagram above through it to the programmer, I can flash it or not.

Also for the microcontroller, I want to order one (TQFP32 QFP32 to DIP32, adapter) for convenience.

1. "I found a wiring diagram on the Internet" - the diagram is correct.
2. According to Feng Shui, this connector is displayed on the board as a system connector (for example, in Arduino).
3. We make boards with such a connector (I recommend taking Arduino ISP)
4. Order a cheap USBASP AVR programmer (Google will help you find it on Ali Express)
5. We flash all products on existing equipment.
6. Everything. Success!!!
In the second picture, both the Programmer and the pinout of the connector (upper part) - the correct ones correspond to points 2 and
3.
"I also want to order one for the microcontroller" - DO NOT. It's too much.

I think it’s not worth contacting the TQFP32 adapter, it’s better to provide a connector for in-circuit programming on the printed circuit board. You will have to ask again and again.
