I have updated my fork Arduino_GFX aka GFX_Library_for_Arduino with support for MCUFriend UNO Shields.
See Arduino_UNOPAR8.cpp databus driver class.
Thanks to this post: https://forum.arduino.cc/t/digitalwritefast-with-uno-r4/1145206/11 from @trevormakes.

Works like a charm! Thanks alot for your work. Arduino R4 Wifi with ILI9486. But took some time to get the examples to work, had to find the Arduino_UNOPAR8 bus type in the source code to get my display to work
I have updated bus class Arduino_UNOPAR8 in my fork. Now uses preset control pins according to the MCUFriend UNO shields instead of pins from constructor parameters.
This allows to achieve faster speed.

The timing test was done using PDQgraphicstest.
As soon as I receive my Arduino UNO R4 minima, I will re-test and then add a Pull Request to https://github.com/moononournation/Arduino_GFX.

Great work! Do post a video of that working 
I have no experience with taking videos, but my Sony Cyber-shot was able...
Can't upload MP4. Trying to zip it. But it is too big.
Don't know how to make it play directly. But GitHub lets you download it.
-jz-
After 25 days I just got a mail that my order will be delayed even further.
I have taken your library and installed it in my IDE, but when compiling it gives me an error that the library does not enter arduino uno rev4. Should the installation be done in a different way than downloading the zip?
I don't understand this message. Please post the complete error message.
Yes, ZIP install should work.

I have the following code
#include "Robot-emotion-images.h"
//#include "structData.h"
//#include <Arduino_GFX_Library.h>
//Arduino_DataBus *bus = new Arduino_HWSPI(16 /* DC */, 5 /* CS */);
//Arduino_GFX *gfx = new Arduino_ILI9341(bus, 17 /* RST */);
void setup() {
Serial.begin(9600);
}
void loop() {
//int16_t wid = gfx->width();
//int16_t ht = gfx->height();
for (int instanceIndex = 0; instanceIndex < sizeof(feliz) / sizeof(feliz[0]); ++instanceIndex) {
const uint8_t* image = feliz[instanceIndex];
//gfx->drawBitmap(0, 0, image, 400, 240, BLACK);
delay(500);
}
delay(10000);
}
and it generates the following message if I compile it
El Sketch usa 33584 bytes (12%) del espacio de almacenamiento de programa. El máximo es 262144 bytes.
Las variables Globales usan 2524 bytes (7%) de la memoria dinámica, dejando 30244 bytes para las variables locales. El máximo es 32768 bytes.
If I activate the library then the following message appears
/home/adria/.arduino15/packages/arduino/tools/arm-none-eabi-gcc/7-2017q4/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/bin/ld: /tmp/arduino/sketches/E89C27448B011D5C0C31789D07E43477/Robot-emotion-slave.ino.elf section `.text' will not fit in region `FLASH'

collect2: error: ld returned 1 exit status
exit status 1
Compilation error: exit status 1```I am to lazy to get that translated, but I assume you used up nearly all available RAM already.
But it is the region FLASH that overflows.
Did you comment out more than the library for the first compilation?
This is what I get compiling PDQgraphictest:
Sketch uses 72816 bytes (27%) of program storage space. Maximum is 262144 bytes.
Global variables use 5024 bytes (15%) of dynamic memory, leaving 27744 bytes for local variables. Maximum is 32768 bytes.
No, just the bookstore. I left the rest of the code the same to make sure it didn't hurt too much.
If you need help or analysis, then you need to provide the complete code, both versions, and with all include files (except the unmodified library).
-jz-
I give you the example that I was trying to do, you will see that it is very simple.
I must upload it as a code that, being new, does not let me upload files. Thanks for the help.

I had to remove the content of the array because it was too much for the web.
You have now been promoted to a higher "trust level" with the forum software, which will allow you to add files as attachments to posts.
I think this is already too much for the FLASH of an Arduino UNO R4.
Maximum is 262144 bytes
but it compiles for me without problem and indicates the message that I showed you above that if it enters.
I am complicated what I want to do with a screen and arduino!
As others have mentioned, your images will not fit as is into the flash memory of these processors.
The board has: RA4M1 256 kB Flash, 32 kB RAM
And your base.c defines a structure: static const uint8_t base[288000]
Which is larger than the flash all by itself.
And I am guessing that your other files are about the same size, as
288k*7 - 256K is pretty inline with the message you posted.
Note: your image file shows it is outputting 24 bits per pixel. Not sure if there would be any way to compress that data down enough to fit. Maybe use an external flash and/or SD Card?
Good luck
Yes, you are too complicated. Your program is too complicated, too big to compile for this processor.
Start with a simpler example, e.g. Clock or PDQgraphicstest.
I now understand what you mean by this, and where your misunderstanding stems from.
Your program is syntactically correct, and the compiler and code-generator accept it.
But the linker complains, because when the code is linked together, it doesn't fit (is doesn't "enter" as you called it).
But linking is part of the compilation chain. If it fails, the whole compilation has failed, and the code can't be uploaded to the processor!
Thank you very much to all,
Several of the things you mentioned occurred, images that were too large and problems with the library version. After solving everything I managed to paint an image on the screen.
Now I find another problem. I want to encapsulate the functionality within a class of its own. But when I pass as a parameter to the constructor of my class
*gfx = new Arduino_ILI9486(bus, A4, 1, false);
So I get very rare compilation errors, like it can't find libraries.
