I'm building a DIY 3D Printer from scratch. I have a GT2560 revA+ board and want to make up a cable to connect a 20x4 LCD. The Rev A+ schematic shows the 10 pin headers for the LCD and SDcard but I dont know how to connect the LCD to it. Is it I2C or direct(RS,E,D4,D5,D6,D7)?
Any help gratefully received..
