## 128x64 & Custom sized OLED Displays
|
||||
### SPI Configuration
|
||||
|
||||
The default display size for this feature is 128x32 and all necessary defines are precalculated with that in mind. We have added a define, `OLED_DISPLAY_128X64`, to switch all the values to be used in a 128x64 display, as well as added a custom define, `OLED_DISPLAY_CUSTOM`, that allows you to provide the necessary values to the driver.
|
||||
|Define |Default |Description |
|
||||
|---------------------------|-----------------|--------------------------------------------------------------------------------------------------------------------------|
|
||||
|`OLED_DC_PIN` | Required |The pin used for the DC connection of the OLED Display. |
|
||||
|`OLED_CS_PIN` | Required |The pin used for the CS connection of the OLED Display. |
|
||||
|`OLED_RST_PIN` | *Not defined* |The pin used for the RST connection of the OLED Display (may be left undefined if the RST pin is not connected). |
|
||||
|`OLED_SPI_MODE` |`3` (default) |The SPI Mode for the OLED Display (not typically changed). |
|
||||
|`OLED_SPI_DIVISOR` |`2` (default) |The SPI Multiplier to use for the OLED Display. |
|
||||
|
||||
## 128x64 & Custom sized OLED Displays
|
||||
|
||||
The default display size for this feature is 128x32, and the defaults are set with that in mind. However, there are a number of additional presets for common sizes that we have added. You can define one of these values to use the presets. If your display doesn't match one of these presets, you can define `OLED_DISPLAY_CUSTOM` to manually specify all of the values.

OLED displays driven by SSD1306 drivers only natively support in hardware 0 degree and 180 degree rendering. This feature is done in software and not free. Using this feature will increase the time to calculate what data to send over i2c to the OLED. If you are strapped for cycles, this can cause keycodes to not register. In testing however, the rendering time on an ATmega32U4 board only went from 2ms to 5ms and keycodes not registering was only noticed once we hit 15ms.

90 degree rotation is achieved by using bitwise operations to rotate each 8 block of memory and uses two precalculated arrays to remap buffer memory to OLED memory. The memory map defines are precalculated for remap performance and are calculated based on the display height, width, and block size. For example, in the 128x32 implementation with a `uint8_t` block type, we have a 64 byte block size. This gives us eight 8 byte blocks that need to be rotated and rendered. The OLED renders horizontally two 8 byte blocks before moving down a page, e.g:

|
|||
|
||||
So those precalculated arrays just index the memory offsets in the order in which each one iterates its data.
|
||||
|
||||
Rotation on SH1106 and SH1107 is noticeably less efficient than on SSD1306, because these controllers do not support the “horizontal addressing mode”, which allows transferring the data for the whole rotated block at once; instead, separate address setup commands for every page in the block are required. The screen refresh time for SH1107 is therefore about 45% higher than for a same size screen with SSD1306 when using STM32 MCUs (on AVR the slowdown is about 20%, because the code which actually rotates the bitmap consumes more time).
