Arduino MEGA 2560 + NHD240128
I try to make a sketch for ARDUINO MEGA 2560 to use NHD240128
i 'm looking for a sample.
i tried but do not succeed for now.
capture of signals :

Hello,
You have quite a bit of code there. Did you test it a little bit at a time or just type it all in at once? How much $$$ do you have invested in your project, I wonde if I could raise that much. I have an application kind of like but not a road map. Maybe we could hehp each other at some time in the not too distant future. I have several years of successful software, but it's not current What language are you programming in?

i type it in one time, but i worked on several versions, it seems that delay() function is not respected for 1ms and around this value. I'm looking for safe instructions for small delay to respect timing diagram. I do not know if my LCD is not dead , i bought it 2 years ago just now that i try it, it sweeps matrix, contrast is enable. I used sample of New Heaven in datasheet. I hope that we can help each other. I do not find functionnal codes on the web for Arduino Uno or other.
i found this link http://en.radzio.dxp.pl/t6963/ but don't have enough expériences to compile with avr-gcc and transfert code without Arduino IDE (i worked on several langages)

Are you seeing anything on the display? Do you have any others to test? Also, can you please provide the full part number of the display?0 -

I found a way to use Atmel Studio 6.2 without transfer interface with my Arduino MEGA2560,
then I tested the code of another person lol
