    Thanks for the moral (& maths!) support.....at last things are starting to take shape (a *big* thanks - as ever - to all on here!)

    Re getting my 'time between comparator interrupts' converted into Hertz, sure enough when I tried to compile the following...

    Code:
    Frequency = 50000000/MyTime  'MyTime is a variable to store the number of timer1 clock counts
    ....some vomit actually jumped out of my screen (I can report that my wife is not happy with the mess on the carpet)

    So I then took one look at some DIV32 examples & augmented the screen's 'dirty protest' on the carpet with my own personal contribution ...I think I need to lie down (perhaps take up another hobby...or maybe dust that 'bus tickets of the world' collection of mine down & actually sort them into chronological order)
