The 72x40 OLED requires selecting the internal IREF, as opposed to the default external IREF. This is an undocumented feature in the SSD1306 datasheet, but is present in the SSD1315 datasheet. It's possible the 72x40 OLED is actually using the newer SSD1315 controller. Sending the IREF select command to SSD1306 displays has no effect on them, so it's added to the init_display() instead of wrapping in an "if width = 72". Also tested on a 128x64 OLED using the SSD1315 controller (smaller ribbon cable) and the proposed change has no effect on the display, as the module comes with the correct current limiting resistor. Internal and external IREF work the same. Fixes issue #7281. |
