I just recently got an Arduino Uno, the Can-bus Shield, a SerLCD backpack from sparkfun, and a 20x4 LCD screen

I just went through the update of making sure that the latest USB firmware was installed on the Uno.  I used the tutorial that had me go into DFU mode, and use Flip.  That install went without a hitch.

My biggest issue is trying to install the SerLCD hex file.  Here is what I tried:

avrdude done.  Thank you.



Just to try to make sure I can actually install a simple Blink test, I compiled and installed Blink via the arduino software, as well as through a hex file from avrdude.  Both worked fine.  Is there something I am missing here??
