Arduino mini will not accept compiled sketch

Development Boards Arduino

I have an Arduino Pro Mini 328 with 09176 Breakout board connected to Win 7 computer.

On connecting I get a RED light is that a problem?

I load Arduino 022 then MultiWii1-7 sketch.

I click compile and it compiles

I click upload and I get an error

It returns an error

Problem uploading to board

avrdude stk 500 getsync not insync reap =x-30

avrdude stk 500 -disable protocol error

A companion program is meant to access the board. This shows connection on COM 3 or Com 18.

When running this I see the TX light flash on the breakout board.

I have connected an external power supply and still get the RED light.

Help would be appreciated.

Any ideas

GALENM,

I suggest the traditional approach of divide and conquer.

Try the Arduino without the breakout board. (What is that breakout board, btw? Posting a link might help us help you.)

Try the minimal Arduino sketch.

Once you get something to work, you can work your way up to what you want.

Happy Hunting,

Eric

Found my problem

Arduino 022 only showed com 3 as a connection.

After running a related program MultiWii Conf1-7 It showed com 18. After running this Arduino also showed com18. Using Com 18 I could upload.

Thanks

sometimes MS Windows incorrectly assigns a new COM port number to a device that’s previously been connected and assigned a different port number. This happens with some brands of USB to serial adapters, but not usually FTDI chip based ones. Including PC boards with an FTDI chip on board. Assuming you have FTDI’s windows drivers and not some generic one.
