EpdFrameUpdate(bMode As Byte)
|
Parameter |
Description |
|
bMode |
Update mode to use: |
EPD_UPDATE_LUT
EPD_UPDATE_NORMAL
EPD_UPDATE_PARTIAL
EPD_SETUP
Updates the screen, causing the information currently in the driver IC's GRAM to actually be displayed.
The update mode corresponds to a specific value written into a driver IC register, and the exact meaning of each value is family-dependent and apply to this driver family specifically, not EPD controllers in general.
Therefore use the general aliases as described for bMode.
Every call is the same two-step sequence: the mode byte is written to Display Update Control, then Master Activation triggers the actual refresh using whichever LUT and settings are currently loaded.
Note: EPD_UPDATE_NORMAL and EPD_UPDATE_PARTIAL currently share the same value — this is a temporary placeholder, not a hardware quirk. As covered earlier, partial update isn't fully implemented yet; once that work is complete, EPD_UPDATE_PARTIAL will trigger a genuinely distinct refresh from EPD_UPDATE_NORMAL. For now, selecting either produces the same full-frame update.
