## Basic Configuration
| Define | Default | Description |
|------------------------|-------------------|----------------------------------------------------------------------------------------------------------------------------|
| `OLED_DISPLAY_ADDRESS` | `0x3C` | The i2c address of the OLED Display |
| `OLED_FONT_H` | `"glcdfont.c"` | The font code file to use for custom fonts |
| `OLED_FONT_START` | `0` | The starting characer index for custom fonts |
| `OLED_FONT_END` | `224` | The ending characer index for custom fonts |
| `OLED_FONT_WIDTH` | `6` | The font width |
| `OLED_FONT_HEIGHT` | `8` | The font height (untested) |
| `OLED_DISABLE_TIMEOUT` | *Not defined* | Disables the built in OLED timeout feature. Useful when implementing custom timeout rules. |
| `OLED_IC` | `OLED_IC_SSD1306` | Set to `OLED_IC_SH1106` if you're using the SH1106 OLED controller. |
| `OLED_COLUMN_OFFSET` | `0` | (SH1106 only.) Shift output to the right this many pixels.<br />Useful for 128x64 displays centered on a 132x64 SH1106 IC. |

| `OLED_SCROLL_TIMEOUT_RIGHT`| *Not defined* | Scroll timeout direction is right when defined, left when undefined. |
