Uno r4 wifi with LCD Display

texploder · December 27, 2023, 6:52pm

This is my first post on this forum so please excuse when i'm doing something wrong.

I have a arduino uno r4 wifi and a 2.5" TFT LCD Display shield from elegoo. I tried some things with the display and my arduino leonardo before and everything works fine. But i cant get it to run on my uno r4 wifi. In the serial everything is displayed like the example of drawn rectangles and this stuff, but the display is always white and not displaying anything. Is out there a guide how to do it?

You haven't mentioned which library you're using, nor given a link to the display, so it's hard to say anything specifically.

In general, most if not all of the existing libraries have to be updated to work with the R4's. Some have been updated, some haven't. For my own personal use, I massaged the MCUFRIEND_kbv library and get reasonable performance out of it. You may end up having to do the same with whatever library you are using.

i have the following lcd display: https://www.amazon.de/dp/B01EUVJYME?psc=1&ref=ppx_yo2ov_dt_b_product_details

I saw there it is for the uno r3 but i dont see why it shouldn´t work on the r4.

when i try to compile the MCUFriend diagnose_TFT_support there are many errors: Error compiling for board Arduino UNO R4 WiFi

This is the complete error log:

Arduino: 1.8.18 (Windows 10), Board: "Arduino UNO R4 WiFi"

I did say "most if not all of the existing libraries have to be updated to work with the R4's". That included MCUFRIEND_kbv. In order to use it myself, I had to go in and figure out what needed to be done to it in order to make it work (and work at a reasonable speed) with the R4's. The author of the library has not yet done so themselves (or expressed any apparent interest in other's attempts to fill the gap either).

The R4s use a completely different processor than the R3s. The low level port manipulation that works on the R3 simply doesn't on the R4 because of that. And because pinMode() and digitalWrite() calls are just so slow, over the years people have gone as close to the hardware as they can in order to achieve decent performance. Bring in new hardware, and you've got to bring in new software to support it. And for the R4, that is still a work in progress at best.

You said you were using a 2.5" LCD, but you linked to a 2.8" LCD. One that looks suspiciously like mine. If the back of yours looks like this

there's a chance that the changes I made to the MCUFRIEND_kbv library might work for you as well. But just a chance; there is no guarantee that the display driver in your display matches what's in mine and some just don't work for other reasons.

I'm happy to share the file I modified so that you can replace it in your library and try it out, but please understand that I am not offering to debug it or support it in any fashion whatsoever. If it works for you, great, enjoy. If it doesn't, oh well it didn't cost you anything to try.

If that sounds like something you'd like to persue, I'm happy to post the modified file here. If not, I wish you well in getting your display working. It's a very satisfying feeling when they finally do work.

texploder · December 27, 2023, 10:14pm

Yeah sorry that i didn't explain everything right. I would really appreciate if you share your modified files. And ofcourse i will debug and try it by myself from this point. I am pretty new in the arduino scene and i appreciate that you helped me this far already!

van_der_decken · December 27, 2023, 10:33pm

In the MCUFRIEND_kbv library, replace the file utility/mcufriend_shield.h with what's below. If your display has an ILI9341 controller, it ought to Just Work. No guarantees on any others. Good luck!

Wow it works! Thank you very much for explaining me everything and saving my Christmas present! Thanks for being patient with me. If it´s okay i´ll mark your answer as the solution

You can´t imagine how happy i am now <3

van_der_decken · December 28, 2023, 12:20am

That's excellent news! Whew! I was a little (or a lot) worried that it would turn out to be a different type of controller and maybe one of the ones that required tinkering with wait states to get it to work. And yes, feel free to mark my reply as the solution so that others will know that your problem has been resolved. Happy displaying!

Fausto_D · January 23, 2024, 9:04am

Hello, I'm using also R4 Wifi plus your display (2,8"), but library Examples that use Touchscreen don't work, any suggestion to solve?
many thanks

David Prentice, author of the MCUFRIEND_kbv library, is sadly no longer with us. See: David Prentice RIP

Genius!! It worked brilliantly for me. Thank you so much

Thanks van_der_decken
Been looking for this solution for months.

zipzap07 · August 16, 2024, 2:22am

I have a ILI9486 display and it only shows a white screen. here

van_der_decken · August 16, 2024, 2:38am

That's unfortunate. My ILI9486 display shield works just fine with an R4. I wish you the best of luck in figuring out why yours doesn't.
