Photographic album using ESP32 and GC9A01 round screen

I have received some modules from AliExpress and the first thing I needed to do was understand how these works. so I made an example where the code loads all pictures from the MicroSD and show them on the screen.

It’s a stupid example but I have needed too many hours because I have had problems to make it work at the same time, because both need the SPI protocol for working. Finally, it was as much easy as how to connect the SCK and MOSI pins at both modules.

The development board is a TTGO T8 V1.8 ESP32-WROVER-B, the screen include the GC9A01 driver.

The development board is not the most I like but it has MicroSD reader, an ESP32 WROVER, and an auto-boot feature. I want to make my own board with these specifications so this development board is perfect for trying everything before making my board.

This is the code of the video:

 

The original example from the library needs the JpegClass, I have needed to modify it a bit because it was made for receiving a file name, but now it is receiving a file directly:
