right_shift function
PostPosted: Tue Jan 11, 2005 4:53 am     Reply with quote
Hi guys,

How do you tell the compiler to use the �Carry� data when you use the right_shift() function. The ASM code generated when I use the right_shift command is �RRNCF�
P.s I'm using the Pic18F452

Thanks

This is the difference between a 'shift', and a 'rotate'. Look at 'rotate_right', instead of 'shift_right'.

rotate_left() puts carry in LSB

shift_left(a,b,c) puts c on LSB, carry it doesn't matter.

C can be 0 or 1, as you wich.


Bye
