MCU I/O EXTENDER ?!?
Hi all,
I need to extend digital I/O pins on mcu.
Looong time ago (late 199x) I use Intel's 8255 to extend number of inputs for some pic mcu (think it was 16f84, can't remember now).
What is best circuit or IC to do it, today?
(I never used GAL, PAL, ALTERA or similar circuits so I'm not interested in that solutions)!
Thanks in advance!
