1. Does anyone have any good schematics for interfacing a PIC16F84A-20 with a HD44780 LCD? 8-bit preferably if thats possible.
2. Will an AC to DC adapter with variable output V (3, 4.5, 6, 7.5 ...) like this: **broken link removed** work to supply a PIC16F84 with power, or will I need any capasitors or similar?
3. What should the clock freq. of my oscillator be if I have a PIC16F84A-20 and I want to get as much as possible out of it? And what if I will just use the pic to control a LCD, are there any cons with using an 20MHz oscillator instead of an 4Mhz?
