Here is my version of the XYZware and Firmware:
You will need an Arduino Micro-controller, I'm using Arduino Duemilanove 328 and Arduino IDe software installed. Download IDE 1.0.6 from Arduino.com:
Once downloaded unzip the folder and from the extracted folder look for the Arduino exe or the arduino icon then double click:
Next, download the arduino code here, right click "xyz_dv_eprom.ino" and click "save link as" and save it to desktop.
Goto the Arduino IDE 1.0.6 compile, Click "File"--->"open"---> choose file: xyz_dv_eprom.ino
A new compiler window will appear with the code in it, you can close the other compiler window if you wish to.
Browse through the code line 352:
This is the default settings and we will change it to 240m or 400m by deleting the 2 forward slash to make it active:
and remember to add 2 forward slashes to the previous line (line 3520 or an error might occur.Once done editing, verify the code by clicking the "Ticked" logo:
Connect a USB cable to you PC and the Arduino, now we can upload the code to arduino by clicking "upload" button:
when upload finished you will see this description at the bottom of the screen:
At this instance you will see a yellow LED flashing on Arduino board meaning the code is ready and running:
Use a jump wire lug to 5V of the Arduino:
then another wire to GND:
and 1 more wire to Pin 7 of Arduino:
All wired look like this:
I used my hand to hold the 3 wires then contact the IC pins accordingly, it is not easy to do by holding the wires with one hand, I would suggest 3Dprint a shell or holder from Thingiverse:
this will fit in to the space where the IC is located then align the wires to correct position holes:
To be continue...
