I am having some issues with the interface for this board, the diagram provided shows the connector CN1 that connects to the LCD display and some of the signals but not what lines are tied to gnd or a diagram for the LCD side. I am making the assumption that the Read / Write line has been tied to gnd but although you only need to write to the display you also need to read the busy flag BF on DB7 in your code which needs the R/W pin to be high when the RS line is low.

Any advice please

Thanks Roy

Hi,

Have you looked at the schematics ?

Thanks for the reply, I managed to work it out once I realised that the driver chip by Sitronix is really the same old Hitachi 44780 so everything fell in place. There is lots of online info about the Hitachi but not a great deal about the Sitronix.

thanks Roy
