Hello
I have what might be a silly question.
I have purchased a APM 2.5 board to start a Arducopter project.
In anticipation and prepping it's arrival I downloaded Mission Planner.
Once the program installed I clicked on a few of the setup steps to see the actual program instead of canceling and going around them. One of those steps was loading the Mission planner firmware.
What I didn't think about was I had my Mega2560 R3 hooked up at the time because I was working on another project.
Mission planner loaded the firmware onto the Arduino board because I clicked yes to load with out thinking I actually had a board on Com port.
The question is: does the firmware that Mission planner loads on the Mega stay in memory and possible effect sketches I load to the board in the future?
I have loaded a couple of sketches since the firmware was loaded and they seemed to work OK but I've noticed pin13 led flashing a steady pulse on one of the sketches that did not use pin13 as output or have a serial read.
Thanks in advance
