Lcd Pic 16f628

[Spadez]

Hi,

Im trying to drive an LCD display (Hitachi HD44780) with a 16f628 PIC. Ive found an ASM file online which should allow me to do it, but im wondering what kind of circuit I would need to make it. Would I need just a power input, my PIC and then the LCD screen contented to the outputs of the PICS or would additional components like resistors be required?

I was also wondering how many connects are needed to connect the LCD screen to the PIC.

Thank you for any help you can give!

hi,
The asm file you are using will determine which pins on the PIC and LCD are connected.
Post the asm file.
