    Sparkfun 8x8 RGB matrix with Backpack;
    I try to install the new Firmware following this guide:
    However, when I run this command:
    avrdude -P /dev/tty.usbmodemfa131 -b 19200 -c avrisp -p m328p -v -U flash:w:RGB_Backpack_v5.hex
    Then receive a signature error
    avrdude: Device signature = 0x000000
    avrdude: Yikes! Invalid device signature.
    Double check connections and try again, or use -F to override
    this check.
    Therfore I turn on the -F flag:
    avrdude -P /dev/tty.usbmodemfa131 -b 19200 -c avrisp -p m328p -v -U flash:w:/Users/i822913/Downloads/RGB_Backpack_v5/RGB_Backpack_v5.hex -F
    At this point I receive a verification error
    avrdude: verifying ...
    avrdude: verification error, first mismatch at byte 0x0000
    0x0c != 0x00
    avrdude: verification error; content mismatch
    I thought I could ignore this validation error, but the original issue (off by one pixel) persists.

No public wish lists :(
