epaper example for a smaller screen such as the 2.9-inch screen

[lboue]

Could you tell me which code needs to be changed in the epaper example for a smaller screen such as the 2.9-inch screen?

I can't find any instructions on the nRF54L15 wiki page.

Hello, I'm sorry for replying to you just now. I tested the 7.5-inch and 5.83-inch ink screens, If you are using our company's ink screen, you only need to change the screen refresh size. I have updated the ePaper example: epaper.py

Refresh according to your screen model, for example, 5.83 inches is 600x448, 0xFF is black and 0x00 is white.
fill_rect(0, 0, 648, 480, 0xFF)

If you have any questions about the wiki, you can raise an issue below the wiki. If you have any other questions, please let me know.

Thanks. What about these models?

• 2.13" Monochrome eInk / ePaper Display with 122x250 Pixels, SPI
• 2.13" Quadruple Color eInk / ePaper Display with 122x250 Pixels
• 2.9" Monochrome eInk / ePaper Display with 296x128 Pixels, SPI
• 4.2" Monochrome eInk / ePaper Display with 400x300 Pixels, SPI

Hello, for these sizes of ink screens, you can use fill_rect to change the length and width to adapt to different sizes of screens, for example:

2.13 inches is 122x250
fill_rect(0, 0,122, 550, 0xFF)
2.9 inches is 296x128
fill_rect(0, 0,296, 128, 0xFF)

If this doesn't work or you have other issues, please post your code and hardware connections.
