I want to display text with arduino, but since arduino is quite big i want to use only the ATMEGA328P, im planning to use e-paper display GDEY075T7 from good display. Here is the link to its page: E-ink screen 7.5 inch electronic paper display 800x480 GDEY075T7_GooDisplay. But im not sure what pins from the display do i need to connect to the arduino. If it would help, i want to show images from a flash disk, use a rotary encoder to scroll between them and maybe a potenciometer to adjust the brightness and possibly fit it onto a PCB. Can you please check what pins i need to use and if everything will work, if you'd also recomend me code to use it would be nice.
Hi and welcome!
This will give you the pins:
Good luck 
Thanks, but i want to know what pins do i need to connect to the arduino from the 24 pin port on the display
The screen is probably either SPI or i2c. Not that hard to look up. Remeber resistors for i2c.
Good luck
Have a look at the sample code, it shows you pins used.
