Maybe I will pick up arduino due as well when I really do this. Any thing special to connect this display with it?

Thanks for the latest release of DCS-BIOS, I was able to get CDU display works with Arduino UNO and a cheap TFT LCD. This is just a proof of concept, no intense test, but the result looks promising. Thought I should document the approach I used. The hardware used is a Arduino UNO R3, and a 3.95 inch TFT LCD screen. Both are from aliexpress and cost about $10 in total. DCS-BIOS v0.5.0 and arduino library v0.2.0 are required. The Arduino display library used is MCUFRIEND_kbv and Adafruit_GFX, detail is here I modified the default font in Adafruit_GFX to get the CDU special characters properly displayed. One small thing: The screen refresh rate feels a bit slow, especially when switch cdu pages. Not sure if that's limited by the hardware or something can be done from the Adafruit display library. I uploaded by sketch file and modifed font to github

Thanks for the quick reply, I will post some detail tomorrow.

CDU Display works! Thanks to the new release of DCS-BIOS, I finally got the CDU Display working with an Arduino UNO and a cheap 3.95 inch LCD from Aliexpress. Almost give up and go for the python pygame with raspberry pi approach. Big thanks to Ian and whoever contributed. :thumbup: I found some small discrepancies in two CDU pages, not sure if Ian want to look into it. I know the issue was not from my side of implementation because I tried pygame code and got same result.
