I am new to Arduino programming and am learning the language from the basics. I downloaded Arduino w/Autopilot application for my PC and have the APM2.5. I have a short program that I wrote that I want to upload to the APM.
I have gone through and compiled the program for Arduino Mega 2560. Also, I have my HAL Board settings to none. The programmer is set to AVRISPmkII. I noticed from device manager that the Mega 2560 is setup on Comm 8. However, I do not see that Comm option in Arduino application. I am using a USB cable interface. When connected, I see a solid orange LED with blinking blue and red LEDs. I am unable to update the driver since Windows XP says that it is the latest one for the mega 2560.
When I try and upload my simple program I get timeout errors. Am I missing something pretty basic? Not looking to do anything fancy. Just want to get a basic program that will do minimal functionality as I learn how to control analog ports, serial ports, do serial printlines, etc. Any help would be much appreciated.
Thanks!

Got it to work! My issue was that the driver that was loaded automatically by Windows XP wasnt correct. I had to go in and manually set the driver to the .inf file for the Arduino 2560 Rev3 board. Now the correct Comm port is shown in Arduino application and I am able to upload my basic sketch.
You don't need an AVR programmer to use Arduino. Please got to Arduino.cc for programming instructions.
