here is my question : I have used an arduino for testing a project, this project works great, and now I want it to build it with real pcb and atmega chip not in ‘development’ mode.
I mean, a PCB that don’t need a computer, the atmega will be programmed once, and that’s all.
Can someone tell me what I need, and what I don’t need from the arduino pcb for a final pcb ?
How can I program the final atmega ? how does I have to change my program for using it in an atmega chip that don’t have the bootloader piece of software ?
I don’t know if it is really clear, but thanks in advance anyway.
