Well, since I got pretty excited that it WORKED, I wanted to do my first post to this forum in praise of Arduino! I hope this is helpful to others just getting started... (I do have the UNO and did several programming projects before trying a DIY project).
I meticulously followed the instructions at http://www.arduino.cc/en/Main/Standalone with the only exception being I purchased the Serial USB board DEV-08165 from SparkFun, instead of the pictured breakout board. Got the 328 chip from Sparkfun also, and a ZIF socket since I'm gonna be swapping out chips often... (This is intended as my DIY progammer).
Carefully checked all wiring, hooked up a 9V batt, and the blink program worked first time! (Endorphins...).
OK, I could not find clear docs on how to hook up the Serial USB board, but I logically followed the pin layout here (duh): http://arduino.cc/en/Main/MiniUSB
Once I got the little board powered, and RX/TX properly hooked to the 328 chip, programming works great (as long as I press the Reset button right when it starts uploading to the chip - I know most of you know this, but I didn't...).
Thanks teding! I looked at the page, except I'm not using the Mini. When that page says the USB Mini's pins are unlabeled, no kidding!
Am I correct in seeing that I can replace my reset button (attached from RST pin to ground on my 328) with a jumper over to the Serial USB board pin labeled #3 on the board's power side? This will do auto-reset?
I'm asking because I don't want to try it anyway and hurt anything since it's working now. Scared, you know... Thanks!
I used the usbmini with the pro (reset line , pin 3 from jp6),
looking at the schematic i am not sure if this is before or after the 0.1 Capicitor.
I think you can try with no harm, if this not works, add the extra capicitor as in this schem,
It look like my project http://arduino.cc/forum/index.php/topic,87747.0.html. I did use a ZIF, USB -mini adapter and I use pin 4 ( top of the USB ) add 0.1 uF in serie with reset pin of the Arduino chip. I program and it work just fine. Just check the picture carefully at the top near pin 4 at the USB - mini adapter.
I tried this scenario and the chip just kept resetting. I don 't have a 0.1uF cap, so that may be my problem anyway. Here's what I tried:
Removed the wiring and resistor from chip Reset pin, and jumpered pin 3 (RTS) from USB board to Reset pin - kept resetting (flash 3 times over and over).
Hooked the wires and resistor back up leaving my jumper in place - this cured the reset problem, but when I try to upload it does not "auto" reset.
No big deal. If I ever get the suggested cap, will try again.
OK... can you check my picture... I use the DTR pin of the USB-mini http://arduino.cc/en/Main/MiniUSB, connect a cap of 0.1 uF in serie with the reset pin of the Arduino chip - pin 1. Try that. And see what happen. If you don't have a cap of the value, try to harvest from some electronics devices or use a different value ( 0.1 uF to 0.47 uF )
