# OLED Driver
## OLED Supported Hardware
128x32 OLED modules using SSD1306 driver IC over I2C. Supported on AVR based keyboards. Possible but untested hardware includes ARM based keyboards and other sized OLED modules using SSD1306 over I2C, such as 128x64.
!> Warning: This OLED Driver currently uses the new i2c_master driver from split common code. If your split keyboard uses i2c to communication between sides this driver could cause an address conflict (serial is fine). Please contact your keyboard vendor and ask them to migrate to the latest split common code to fix this.
## Usage
To enable the OLED feature, there are three steps. First, when compiling your keyboard, you'll need to set `OLED_DRIVER_ENABLE=yes` in `rules.mk`, e.g.:
```
BOOTMAGIC_ENABLE = no
MOUSEKEY_ENABLE = no
STENO_ENABLE = no
EXTRAKEY_ENABLE = yes
OLED_DRIVER_ENABLE = yes
```
This enables the feature and the `OLED_DRIVER_ENABLE` define. Then in your `keymap.c` file, you will need to implement the user task call, e.g:
```C++
#ifdef OLED_DRIVER_ENABLE
void oled_task_user(void) {
// Host Keyboard Layer Status
oled_write_P(PSTR("Layer: "), false);
switch (biton32(layer_state)) {
case _QWERTY:
oled_write_P(PSTR("Default\n"), false);
break;
case _FN:
oled_write_P(PSTR("FN\n"), false);
break;
case _ADJ:
oled_write_P(PSTR("ADJ\n"), false);
break;
default:
// Or use the write_ln shortcut
oled_write_P(PSTR("Undefined\n"), false);
}
// Host Keyboard LED Status
uint8_t led_usb_state = host_keyboard_leds();
oled_write_P(led_usb_state & (1<<USB_LED_NUM_LOCK) ? PSTR("NUMLCK ") : PSTR(" "), false);
oled_write_P(led_usb_state & (1<<USB_LED_CAPS_LOCK) ? PSTR("CAPLCK ") : PSTR(" "), false);
oled_write_P(led_usb_state & (1<<USB_LED_SCROLL_LOCK) ? PSTR("SCRLCK ") : PSTR(" "), false);
}
#endif
```
## Other Examples
In split keyboards, it is very common to have two OLED displays that each render different content and oriented flipped differently. You can do this by switching which content to render by using the return from `is_keyboard_master()` or `is_keyboard_left()` found in `split_util.h`, e.g:
```C++
#ifdef OLED_DRIVER_ENABLE
uint8_t oled_init_user(uint8_t rotation) {
if (!is_keyboard_master())
return OLED_ROTATION_180; // flips the display 180 degrees if offhand
return rotation;
}
void oled_task_user(void) {
if (is_keyboard_master()) {
render_status(); // Renders the current keyboard state (layer, lock, caps, scroll, etc)
} else {
render_logo(); // Renders a statuc logo
oled_scroll_left(); // Turns on scrolling
}
}
#endif
```
## 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.|
## 128x64 & Custom sized OLED Displays
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_DISPLAY_128X64` |*Not defined* |Changes the display defines for use with 128x64 displays. |
|`OLED_DISPLAY_CUSTOM` |*Not defined* |Changes the display defines for use with custom displays.<br />Requires user to implement the below defines. |
|`OLED_DISPLAY_WIDTH` |`128` |The width of the OLED display. |
|`OLED_DISPLAY_HEIGHT` |`32` |The height of the OLED display. |
|`OLED_MATRIX_SIZE` |`512` |The local buffer size to allocate.<br />`(OLED_DISPLAY_HEIGHT / 8 * OLED_DISPLAY_WIDTH)`|
|`OLED_BLOCK_TYPE` |`uint8_t` |The unsigned integer type to use for dirty rendering.|
|`OLED_BLOCK_COUNT` |`8` |The number of blocks the display is divided into for dirty rendering.<br />`(sizeof(OLED_BLOCK_TYPE) * 8)`|
|`OLED_BLOCK_SIZE` |`64` |The size of each block for dirty rendering<br />`(OLED_MATRIX_SIZE / OLED_BLOCK_COUNT)`|
|`OLED_SOURCE_MAP` |`{ 0, ... N }` |Precalculated source array to use for mapping source buffer to target OLED memory in 90 degree rendering. |
|`OLED_TARGET_MAP` |`{ 48, ... N }`|Precalculated target array to use for mapping source buffer to target OLED memory in 90 degree rendering. |
### 90 Degree Rotation - Technical Mumbo Jumbo
OLED displays driven by SSD1306 drivers only natively support in hard ware 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 Rotated Rendering 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 OLED Height, Width, and Block Size. For example, in the default 128x32 implementation 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:
| | | | | | |
|---|---|---|---|---|---|
| 0 | 1 | | | | |
| 2 | 3 | | | | |
| 4 | 5 | | | | |
| 6 | 7 | | | | |
However the local buffer is stored as if it was Height x Width display instead of Width x Height, e.g:
| | | | | | |
|---|---|---|---|---|---|
| 3 | 7 | | | | |
| 2 | 6 | | | | |
| 1 | 5 | | | | |
| 0 | 4 | | | | |
So those precalculated arrays just index the memory offsets in the order in which each one iterates its data.
## OLED API
```C++
// Initialize the OLED display, rotating the rendered output 180 degrees if true.
// Returns true if the OLED was initialized successfully

bool oled_init_user(bool flip180);

// Returns true if the screen was on or turns on
bool oled_on(void);
// Can be used to manually turn off the screen if it is on
// Returns true if the screen was off or turns off
bool oled_off(void);
// Basically it's oled_render, but with timeout management and oled_task_user calling!
void oled_task(void);
// Called at the start of oled_task, weak function overridable by the user
void oled_task_user(void);
// Scrolls the entire display right
// Returns true if the screen was scrolling or starts scrolling
// NOTE: display contents cannot be changed while scrolling
bool oled_scroll_right(void);
// Scrolls the entire display left
// Returns true if the screen was scrolling or starts scrolling
// NOTE: display contents cannot be changed while scrolling
bool oled_scroll_left(void);
// Turns off display scrolling
// Returns true if the screen was not scrolling or stops scrolling
bool oled_scroll_off(void);
// Returns the maximum number of characters that will fit on a line
uint8_t oled_max_chars(void);
