Hello,

I'm sorry for my explicit greeting....(indeed i'm a participant of Avrfreaks...)

OK, I've found it, the convertion is very easy,

eg. 253d ==> FDh
(253d is saved in two memery loc)
We just have to make the next calc. (hexadecimal of course)...

=> 2d x 64h = C8h
=> 5d x 0Ah = 32h
=> 3d (x 01h) = 03h
+ _____ (the addition gives us...)

FDh

easy isn't it!

PS: this was NOT a homeword assignment, and i don't understand what the problem should be if it was a homework assignment, bear in mind that a forum is 'invented' to share problems and solve them together,even it is (a piece) of homework, a student has to learn it also,....

greetz, and no hard feelings :)
