Title: Upload code to atmega328p?
Post by: Mlkebai on April 09, 2021, 10:53:01 am
Hi, all
I want to design atmega328p (https://www.apogeeweb.net/circuitry/atmega328p-microcontroller-datasheet-pinout-circuit.html) on PCB...
One method to upload code is using Arduino Uno. If I disconnect the wires from arduino uno side but left them in atmega328p side, will be there any problem such as open circuit because of wires?
My idea is to solder the wires in PCB and when I need to upload code or monitor data I connect these wires to arduino uno.

Is there anyone have ideas of it? I will be glad to any suggestions. Thank in advance. :D
