Programming the SPLat board to work with SPLogger can range from no extra effort, through to a few basic provisions up to creating a moderately sophisticated program.
The minimum consideration you should give to "SPLogging" is to concentrate the data you wish to log into a tight group of RAM locations. The SPLatLink protocol can only extract 16 bytes of contiguous RAM in one message, so the more spread out the RAM locations you are monitoring, the slower it will become.
Here's the quick and dirty SPLat program I used for testing SPLogger in an MMi99 with LCD. It tags all of RAM with its own address. Then it maintains an integer in 1 and a floating point number in 2-5, allowing both to be modified from the MMi99 front panel. Location 0 is used as a trigger by being incremented every second.
