I'm sure this is covered in the list somewhere but the list wont let me search "pic to pic communication" as the word pic is under 3 letters.

I want to sample a pulse in but need to sample it for upto 2 seconds. The problem is I need to do other stuff and display results every 1/2second.
I was thinking about using 2 pics and have one just sampling and producing an 8bit answer using 8pins and then reading the 8pins with a second pic?
This way the second pic always gets the lastest reading without having to waiting 2 seconds.
Any better ideas?
Could I use 1 x eeprom with one writing and one reading?
Probably not
