When I first got started programming Nevo remotes, the files on Remote Central really helped me get started. This is a file from a 60' Viking Yacht that I worked on recently. It controls all of the equipment in the salon. I setup a seperate device section that allows you to get into all of the lesser used functions for each piece of equipment.
There are discrete on/off and video input codes for the Sharp LC37d43u which I have tested on other Sharp LCDs. There are also discrete on/off and input codes for the Lifestyle 38. These will work on other lifestyle systems as well.
This is a complete file that has a couple custom animations that I used for countdowns during long macros. I used a voltage sensor to let the remote know when to use the long version of the animation when the television is off, or the short version when the television is on. There are also many icons that I created myself using GIMP photo editing software. This file is used in the salon on a 60' Viking Yacht.
