I am a newbie to ESP32 and E-ink display. I have a Waveshare 10.3 inch E-ink display with IT8951 driver.
I want to use it with one of these Wemos D1 R32(ESP32)( or a ESP32 or a ESP8266) board because of the ultra low power consumption during deep sleep.
I found this below GITHUB library and was successfully able to get my display to work and displays a single image of 400*400 perfectly everywhere on my screen.
But, now when I want to have to load more than one image or a bigger image, I run out of memory(even if I declare PROGMEM). I want make a offline Eink photo frame that loads image arrays from the SD Card. The size of each is  and the .ino file is around 800kb.
Could you please guide me how to load the .ino files from the SD Card.
or If I cannot load .ino arrays, can you let me know how I can save the array as a .txt file and load it into the Arduino without running out of memory.
Thanks in Advance.
