I have struggled using the verilog example code used to control the LCD expansion module. I found a VHDL project over at openCores which I have forked for use with the Mimas V2 board. It could also be used with the Elbert V2 board if the ucf file was updated as required. I've written up all that I did and shared the code on my blog which is here: http://langster1980.blogspot.co.uk/2016/01/numato-mimas-v2-controlling-16x2-lcd_24.html Cheers People Alex
