Add 3.7" GDEQ037T31 and 2.9" GDEM029E97 epapers from Good-Display #81

Closed martinberlin closed 6 months ago

martinberlin commented 1 year ago

Notes: Although 2.9 full update is working correctly, it's leaving the 1st Y line at the other end of FPC always black, that should be gone in the final version.

https://github.com/GoodDisplay/E-paper-Display-Library-of-GoodDisplay/tree/main/Monochrome_E-paper-Display has to be one of this 2.9's wait for Good-Display confirmation

Thanks @gooddisplayepaper started with the 2.9" and the fullscreen update is already working fine. But I'm getting an initial black line (Check the video) that still could not get rid of. Then will try to get fast partial update working before starting with the 3.7"

@gooddisplayepaper can you please check this example: https://github.com/GoodDisplay/E-paper-Display-Library-of-GoodDisplay/tree/main/Monochrome_E-paper-Display/2.9inch_GDEM029E97_SSD1675

This is declaring function EPD_Part_Init but never using it anywhere. Sending the same commands I still could not see any partial update

Closing here. Reopening when @gooddisplayepaper enginners publish some partial update examples
