I'm new to microcontrollers, and have been using the Arduino for a couple of weeks now. I would like to develop my projects using the Arduino IDE, and board, then remove the programmed chip and place it into a circuit board/breadboard.
I think I've got most of this figured out, but I want to keep my component count low. So how do you run the chip without an external clock? I tried the ATMega datasheet, but I'm afraid I don't know enough about AVR programming to make sense of it. I think I have to set some fuses for this, but I haven't a clue on how to do that.
My projects are mostly LED based, (no motors, solenoids, etc..)
Any advice and sample code would be greatly appreciated!
When I ordered my Arduino from Modern Device, I ordered it with an extra 168 with the bootloader already installed. I took this chip and put it on a breadboard with a 16mhz xtal and it's working fine. There aren't that many connections to configure to allow it to be programmed like a regular arduino board.
Sparkfun.com has a pretty decent tutorial section that shows how to do most of this work.
