Arduino Programming Allegro A1128 Hall Effect: Hardware/Code Solution

I need a solution for Programming the Allegro A1128 Programmable Hall Effect Switch using an Arduino and whatever extra hardware is needed to supply programming level Voltage levels. I believe this requires a solution for providing a supply voltage at 5V, 12V, 24V levels in pulses.. First Device will have 24v Battery, 5v regulator(s) and likely a 12V regulator. Would this be possible with only a 12V supply? Only a 5V? Hardware: solution that's reasonably efficient (min components/cost of components), for providing the programming levels. PWM/Mofset? Transistor? I have hobby level skills and don't know what the best way is. Software: at minimal, a solution that works and I can understand. I think I'm only going to work in Try mode (not permanently programming device) so I don't necessarily need the ability to blow Efuses. At best, a subroutine or library that allows for easy programming of all functions. I would like as much code comments as possible. So that I can figure it out all out. The idea is, to make code that me as a hobbyist and beginner programmer will be able to use. Please Bid Honestly. I wont give extra money unless there is a good, explained reason. Lowest Bid from freelancer who sounds like they can accomplish they task will win. Understandable English, particularly in the code comments is a HUGE plus. I need you to help me understand what the values being programmed are actually accomplishing.
