where can i get connections to the lcd display. what type of lcd display can be used?
from the plug in,
PCF8574 = 0x20-0x27
PCF8574A = 0x38-0x3F
search for PCF8574 or PCF8574A relating to an i2C bus based 16x2 LCD.
Most appear to be HD44780 based LCD (16x2 chrs) with an I2C adaptor connected to them..
i2C means only a couple of GPIO pins are required, otherwise you need a lot more, I think up to 8.
I'm looking to purchase an LCD myself,, hundreds out there

Can you provide connection diagram of raspberry pi with lcd display in detail with circuit diagram and components?
