As we are not still able to make it work, I have few questions.
About the wiring, we are not sure about DEN signal - we have connected it to the EMX LCD_EN - is it correct? DISP signal should be just on/off so it is just 1 - display is really on so I presume there is no problem.
According to a datasheet I set the following LCD configuration via FEZ config:
@ Marten - The display you are using is one of the ones that our recently announced Display NHVN supports. You can always compare its schematic with your board to see if the pins are connected correctly. The timings you listed are correct.
Thank you guys for hints. The problem was the we have connected pin no. 35 to the logical 1 and it should really stayed NOT CONNECTED as it’s in the pin description documentation. Now it’s working like a charm.
