* Tests to identify display model * (InkHUD) SSD1682 controller IC Has a few quirks, gets its own base class * (InkHUD) E0213A367 Display For Heltec Wireless Paper V1.1.1, V1.2 For Heltec VM-E213 V1.1 * (InkHUD) Select display model at boot * (BaseUI) Wrapper to combine multiple GxEPD2 drivers Workaround for issue of GxEPD2_BW objects not having a shared base class. Allows us to select a driver at runtime. https://github.com/meshtastic/firmware/issues/6851#issuecomment-2905353447 * (BaseUI) Select E-Ink model at boot * (InkHUD) SSD1682 deep sleep * (InkHUD) No deep sleep for SSD1682 * (InkHUD) Fully no-op deep sleep for SSD1682
