Using the Arduino Uno code for reprogramming.

The code originally came from this web site http://elm-chan.org/works/avrx/report_e.html The command line options have been replaced with a menu system.  The purpose of the menu system is solely to program the Arduino enough to get the SPI serial interface to work.  Once you have done that you can then use other software to finish off programming your Arduino.

Here is a sample of what the r serial read fuses option outputs:

You will need to solder a wire on to the XTAL1 track.  This can be done by soldering on to the bottom connector of the crystal.  It is best to use a wire with a connector pin on the end.  That way you can connect and disconnect from the wire from resistor pad 6.  With a pin on the end of the wire from  resistor pad 6 you can use a breadboard to make the connection.  When you are programming in parallel mode XTAL1  must be connected to resistor pad 6.  When you are using the serial methods the wire must be disconnected.  The exception to this might be if your Arduino is programed to use it's internal clock.

Wire soldered on to XTAL1 track.

The code is supplied in Microsoft Visual Studio 6 format.  That's a very old version which most people are not likely to have.  The program is already compiled and is in the avrpp-xp\Release folder. It is called avrpp.exe.  You can double click that to run it and it will run in a cmd prompt window.  You can then choose an option to run from the program menu.

The code is downloadable as a .zip file avrpp-xp.zip from here https://steve54798.wixsite.com/filecab/code 

To allow direct access to the printer port on your PC in Windows XP you must have the 3rd party giveio.sys file either in the same folder as the avrpp.exe program or some where in the Windows path.  C:\windows\system32 is a good place to put it.  The giveio.sys file can be downloaded in the .zip file here https://steve54798.wixsite.com/filecab/code
