ARDUINO MEGA 2560 WITH ILI9341

[umairml]

Unable to get display on ili9341 using arduino mega 2560?
I have no specific code to run please guide me....

 

[Ian Rogers]

Check out the example.... You have to wire the LCD up exactly the same..

Ok its ok about wiring but what about code to run simulation....

hi,
Have you set the IM pins correctly for SPI operation..?

[Ian Rogers]

The code is with the example..

 

[umairml]

here is all i am doing. Now please guide me what is wrong with my code or my circuit simulation.
My brain is exploding....
Please help

Hi Umairml .. .

Welcome to ETO .. .. .
I'm not sure you have your interface connections right yet, they don't seem to match those on the ILI9341 datasheet.
I would suggest you use one of the example sketches in Arduino IDE to make sure your connections/setup is correct before you try to run a more complex sketch.

Look here .. ..

Then when you have that running correctly you have a fighting chance with the more complex sketch.

I hope that helps .. ..

IM0 low IM1~3 high

IM0 low IM1~3 high

Yes, currently shown as IM1 = low; IM0, 2 & 3 high.

Also interface between screen and Arduino - I can't read the pin ID's on the screen ( ageing eyesight ) but they don't look right ? The Arduino example sketches have the pin ID's marked out to make it easy to identify them.

h,
You show a Vs =1.5v, does that fall within the specified range.?

Thank you now it is working. Thank you. Thank you

hi,
Can you tell us what you had to do, to fix it?

There was wiring issue after correct connection and using of correct library with arduino it is now working. Actually i was using library of arduino uno after search i got that it was uno library as pin initialization was wrong but all good now after reading arduino datasheet.
