Arduino Uno with ICSP

[Mia (Gast)]

can someone show if my schematic is correct ?

I want to use as Crystal the standard from  Adafruit

the power will coming from Battery

micrcontroller : Atmega328P-P

Looks fine

Do you really need 16 MHz and 5 V? I would prefer 8 MHz and 3,3 V 
(without the DC converter) if possible.

Thank you to check it :)
internal clock at 8 MHz is not as good as an external 16MHz or 8MHZ
I want to making a good chip , wich i can using in the future for 
everything .
i will using arduino ide to get the Hex file , and then programming with 
AVR mk2 using AVRdudess , so my chip will be fast .
the is my reason

What about Pin 22(GND)?

Why with AVRdudess?
And not direct by Arduino?

Thank you to show it and see that Pin 22 is not visible :)
Pin 22 is with Ground in the Footprint in Kicad ( wich i used ) but is 
not shown in Schematic

Avrdudess is simple to use than arduino ide with avr mk2 , arduino ide 
can not see the mk2 , i needed to re install the driver to libusb .
i try it on Windows 11 , but that was difficult !

Avrdudess uses AVRdude
Arduino IDE uses AVRdude

So your assumption must be wrong.

Suggestion:
View/edit the programs.txt file.

Then you should use the strongest microcontroller that you can get.

If you fear that 8 Mhz is too slow, why not use another Microcontroller 
which can be much faster and has much more memory?

Also consider that most peripheral chips that have been developed within 
the last 20 years cannot run at 5 V. It is already a bad choice today 
and will become worse in the future.

A few characters have been lost.
Correct: programmers.txt

No problem, use an external 8 MHz Crystal *). Look for Arduino Pro Mini, 
it is also sold as 8 MHz version and supported by Arduino-IDE.
