I bought a hd44780 lcd and soldered pigtails to all 16 leads. After not getting anywhere with the micro (PIC18f8722) i tried just manipulating inputs with a breadboard, but I cant even get anything with that.
I have my backlight and contrast working properly, but as soon as I put my VDD to 5vdc, every other input to the lcd goes to 5vdc. Is this normal and I am just misunderstanding this conceptually, or is the lcd damaged?
