LCD1602_8 data

         Programs should be written in their own style

******************************************************

** This is a 1602 program written when learning msp430g2553 microcontroller **

** Time is accurate to us, basically no garbled characters **

** P1 is the data output port **
** rs is connected to p2.1 **

** rw ground **
** en connect to p2.0 **
