Why would you do that (except for not having the newer PICs *yet*)? Yes, with the 18F452. Why "or"? Yes, it is possible with the sid v2 hardware. On v1 they're a bit clustered in different places. It's all documented on ucapps.de though. As long as you DON'T upload the "no cs" version, the LCD will work right away, although you might wanna make some changes in main.asm to change the display size.
