Minimal circuit standalone operation

Other Hardware 3rd Party Boards
1

Hello,
I'm trying to operate the ATmega328 as minimal circuit standalone on a breadboard (without external clock).
I followed the instructions as appear in 'Learning' section of the site, including unzip 'Breaboard'.
The problem is that i can't see 'ATmega328 on a breadboard (8 MHz internal clock)' in the Tools>Board menu, as expected, so I can't upload programs.
The ATmega328 taken from UNO board so it has BootLoader.
Anyone can help?
Thanks

An update:
The solution is to insert the unzip file into sub-directory TOOLS (not exactly as written in the instructions) and the new board appear.

Is it placed in the folder 'hardware'?

Cheers,
Dylan

yes. I create sub-folder.

Try the Lilypad Arduino w/ATmega328 from the boards menu. I believe it runs on internal RC 8 mHz clock, no external crystal needed..

I don't think any of the boards are internal clock only.
May need to copy a board type and change the hi/lo/extended fuses to suit.

I stand corrected - I always assumed the lilypad 328 at 8 mHz used internal RC but I just now finally looked at the schematic and see I was wrong. It does have a crystal. Fuses will have to be changed.

That Lilypad file with fuses changed to High 0x62, Low 0xDB looks like it should work for internal 8 mHz RC and 2 KByte boot loader size.

OK, this will be easier. You can download the board file "ATMEGA 328 on a breadboard (8MHz internal clock)" that you need from this site and it tells you how to install it:

You will need to close your IDE and re-open it before it will appear in your Tools | Boards menu

I used these instructions without any problems

Thanks! I will give it a try.
