Title: 16 bit bus for NHD-2.4-240320SF-CTXI#-FT1
Post by: jollyrogerlabs on November 06, 2014, 03:43:02 PM
Hello all,
I'm currently running the display with a standard Arduino Mega2560 using logic level shifters and everything is working fine for 8 bit bus code based off the code in the application note.  However, when I modify the code in what appears to be an appropriate way (based on the New Haven Display documentation and the ILI9341 data sheet) and then tie IM0 to GND, everything stops working completely and all I get is a white screen.  Is there any example code for this case floating around, or are there any pitfalls that I should be aware of?

There are no pitfalls I am aware of.  All that is needed is IMO = '0', and the 16bit mode should work fine, assuming your code is good.  The example code on our website is for 16bit mode, here:
