How to connect USBASP to a bare atmega328p

[stoffej]

I have spend a long time trying to sort this out.
But I getting more and more confused.

I want to burn the bootloader to create this sensor.
https://forum.mysensors.org/topic/2067/my-slim-2aa-battery-node

I have

• usbasp
• a few ardunino uno
• bare atmega328p
• not enough knowledge in burning bootloaders =(

But how do I connect the usbasp to a bare atmega328p without external crystal to burn the bootloader??
Can I connect the usbasp to the arduino unos ICSP port?
Like this

And use this good guide mysensors burn bootloader

The ICSP connector that is nearest to the mega328 chip is the one I planning to use.

@stoffej - check this out: https://www.arduino.cc/en/Tutorial/ArduinoISP as well.
Im not using the usbasp but a normal usb cable to my uno, then i use the uno as programmer.
usbasp is a programmer itself and you cant use both.

If you want to use the usbasp you need to connect the right pins from it to a breadboard where you have the atmega.
Im sure there are more ways to do it.

You can run your code without a bootloader: Arduino IDE -> Sketch -> Upload Using a Programmer

For programming optiboot and setting the fuses, I used https://github.com/WestfW/OptiLoader

Just take out the Atmega328p from your Arduino Uno, put in a new Atmega328p, connect your USBASP and burn the bootloader.

and perhaps some parts of this howto can help you too. not the same bootloader but I use usbasp. Yes you need to use your icsp conenctor or the spi port + rst pins if you want.
