If you have enough memory, it should work on any CPU. Have you encountered a problem? What code have you tried?

Hello
Play_all_sd_files.ino file
does not recognize SPI.begin (int, int, int, int);
does not recognize SD.begin (int);
Try with
SPI.begin ();
SD.begin (); , compiles but st7789_nocs flashes does not show images

I have all of that equipment - I'll give it a try and make any necessary changes to make it work.

It compiles file without modifying anything. It sounds like you're having issues with SPI not configured correctly. Have you probed the MOSI and CLK lines to see if you've told it the correct pin numbers? I know that the software works, so I can't help with your particular setup. Do you have an SD card connected to your STM32? Have you tested that it reads the file successfully? There are too many parts to fail for me to help you. Why not try the demo code which draws a GIF file from memory first? That eliminates one of the unknowns in your setup.

@jhonnyx161 you can eventually try this:

SPIClass *my_spi = new SPIClass(mosi, miso, sclk, ssel /* default= (uint8_t)NC */);
my_spi->begin( cs_pin );

// then later

SD.begin( sdcard_cs_pin, *my_spi );

There are multiple implementations of the SD library and I can't account for all of them in my example sketches. You'll have to solve this one yourself.
