"I posted this in the Micro forum because I am using the LCD with a microcontroller.  My question is software based though, so if the post needs to be moved I'm sorry. here goes: *edit 2 questions\r\nI recently got a LCD that I want to use on a bread board that has a PIC & 4x4 keypad already in working status(from class last semester).  I have seen a LCD used before where Hello World is printed.  I know that a Header file must be included in the program otherwise the LCD wont work.\r\n1)  Can all LCD's use a standard header file, or do I need to create one using the Instructions section of the datasheet?  \r\n\r\n2)  If a standard header doesn't work, is it easy to create the header file using the datasheet?\r\n\r\nThis is the data sheet for the LCD I have:\r\nhttp://www.hnqhlcd.com.hk/lcm/lcd_datasheet/UC202A-YP-FB-N-LB-YG.pdf\r\n\r\nThanks\r\n-Yeti"
