Rachel,<div><br></div><div>Sorry I should have provided instructions,</div><div><br></div><div>I believe these are the steps you need to take:</div><div><br></div><div><pre style><font face="arial, helvetica, sans-serif">1)
compile the program in the IDE
2)
use the run/upload button to attempt to upload the code
this step generates the <span class="il" style="background-color:rgb(255,255,204)">ihex</span> file, and it does not matter if
upload actually failes. The important things is to get the <span class="il" style="background-color:rgb(255,255,204)">ihex</span> file
3)
Use the script ihemerge.py script to generate a new <span class="il" style="background-color:rgb(255,255,204)">ihex</span> file that
combines the firmware for the mega1280 (which is compatible with the
2560) and the <span class="il" style="background-color:rgb(255,255,204)">ihex</span> file generated by step2
python <span class="il" style="background-color:rgb(255,255,204)">ihexmerge</span>.py
arduino/tvm/firmware/tvm-avr-atmega1280-16000000-arduinomega.hex
yourfile.<span class="il" style="background-color:rgb(255,255,204)">ihex</span> > combined.<span class="il" style="background-color:rgb(255,255,204)">ihex</span>
4)
use avrdude to upload the file, something like this:
bin/avrdude.exe -C bin/avrdude.conf -V -F -p atmega2560 -P COM4 -b
115200 -c stk500v2 -D -U flash:w:combined.<span class="il" style="background-color:rgb(255,255,204)">ihex</span></font></pre><div><br></div><div>You'll need to have Python installed for the script to work,</div><div>
