Hi Bill
Go to my post #311 for how to burn the firmware.
Download the firmware from here
Open ReVolt/LCD Firmware - EcoModder
Unzip it then follow the directions in my post.
Download the User Manual here
Open ReVolt/PCB Schematics - EcoModder
The user manual has a section on how to change the settings to suit your system. Give it a go & if you run into problems, one of us here can help you.
