[Solved] Program Pro Mini w/ usb serial dongle?

bilbo:
Sorry for being unclear, that is what I mean. Buying another ftdi makes no sense when you already have one in the duemalinove .

OK, to use the FTDI on your duem... to upload to the pro mini:

Remove 328 chip from socket on the duem.
Wire duem tx pin to promini tx pin.
wire duem rx pin to promini rx pin.
wire duem reset pin to promini DTR pin
wire duem ground pin to promini ground pin
wire duem +5vdc pin to promini Vcc pin // ignore this if powering promini in some other way

Select promini type board in IDE, select normal comm port number used by the duem, load sketch, press upload.
