I have modified the script to search backwards for the most recent ET file, it a will also create a base 0’d file if the directory is empty. Currently I’m working on modifying the OS firmware to work entirely off the SD card allowing for more accurate programs, more programs, and better history from which trends can be recognized and adjustments could be made. I haven’t posted it to github yet because I don’t want to brick anyone’s hardware. Currently it is a pseudo functional alpha version. Another week or 2 and I should have a version worth posting.
