1. A Data-Entry routine to capture individual YEAR, MONTH, DAY, HOUR and MINUTE. You have the LCD screen, do you also have say three buttons available that we can assign to UP, DOWN and SET function?

YES, there are three Buttons


2. CalculateLinearFromDate routine, to calculate Linear Days from the Date component (again a form of Julian Date - the inverse of my CalculateDateFromLinear routine.


I think the principle is clear (eventhough I don't have the code ready yet)


3. A method of generating the 32-Bit number containing the Linear Seconds to feed the iButton.


This is the challange !
