Regression in 8.1.0 due to ACEP-patch (refresh fails on e-paper) #7734
Comments

Fixed this by setting grayscale to True in the constructor. But this seems to be more a workaround than a fix, because the display is monochrome and not a grayscale display. So the switch to a refresh-sequence does not seem to be the root cause after all. |

The code considers monochrome to be grayscale (versus having color.) What driver code are you using? It should set grayscale correctly. |
|
It is an UC8151-chip. I will create a PR which fixes the board.c by setting grayscale to true. |
|
I think #7777 may fix this more broadly. (I saw a similar issue on the forum.) |

Fixed by #7777 |

Description
PR 931c7c1 (ACEP) changed the interface to the EPaperDisplay class replacing the (single byte) refresh_display_command with a refresh_sequence. Since this PR the Badger2040 flashes during refreshes but the screen remains black.
