[Solved] Standalone 328p

Using Arduino Microcontrollers
1

Hello,

I programmed an atmega328p through an Arduino.
Normally, this chip doesn't have any bootloader.
I wired a resonnator (16 mHz) to the chip, but it runs 2 times slower than it should, so I think it is using the internal clock.
When I compiled the sketch, I did it for an Arduino Uno, so theoretically using the external crystal.

Do you have any ideas why it doesn't work?

Thanks by advance

It's the Burn Bootloader process that sets the configuration fuses that select the clock source.

I hoped it was not but I'll deal with it...

Thank you.
