Uploading sketches to a standalone arduino uno on a bread board

I have one of these: http://www.ebay.com.au/itm/251175182899?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

I am trying to figure out how to upload sketches to the atmega chip.

So far, if I connect the Rx and Tx of the atmega chip and the FT232 appropriately and manually hit the reset button on the atmega when the sketch finishes compiling, then I can successfully upload.

But I can't figure out how to use the CTS and/or DTR pins on the FT232 to automatically reset the atmega chip.

If I connect either of these to anything then I get an upload error message along the lines of the atmega not being in sync.

DTR thru 0.1uF cap to Reset pin.
10K pullup resistor on Reset pin.
DTR going low is turned into a reset pulse by the cap and resistor.

For the Arduino auto reset feature to work you need to add a series .1ufd capacitor between the DTR pin and your AVR chip's reset pin. Also a 10k pull-up resistor from +5vdc to the AVR reset pin is recommended.

CR beat me again :wink:

BEAUDIFUL! I am all set.
Thanks mate!

No problem. Can see that in my sleep these days.
