There are many PIC processors that can run at 3V, the PIC16F916 is not the only one. Note that at 3V the maximum frequency for this chip model is 10MHz.

Some can, others can't. Please provide more details about the LCD: type number, manufacturer, etc.

These are standard formatting parameters for the printf statement. For a detailed explanation check any C book describing the printf statement. |

The LCD should be able to interface with a 3.3V controller. The minimum level that is, usually, required to be considered a '1' is 2.4V. When the output, of a 3.3V part, swings high it should go above this level. The only problem is that most LCD's require 5V for their onboard IC's. There should be 3.3V LCD's around but I, personally, haven't looked for any before.
