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: @@ -232,6 +270,8 @@ However the local buffer is stored as if it was Height x Width display instead o 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). + ## OLED API ```c @@ -253,6 +293,11 @@ bool oled_init(oled_rotation_t rotation); oled_rotation_t oled_init_kb(oled_rotation_t rotation); oled_rotation_t oled_init_user(oled_rotation_t rotation); +// Send commands/data to screen +bool oled_send_cmd(const uint8_t *data, uint16_t size); +bool oled_send_cmd_P(const uint8_t *data, uint16_t size); +bool oled_send_data(const uint8_t *data, uint16_t size); + // Clears the display buffer, resets cursor position to 0, and sets the buffer to dirty for rendering void oled_clear(void); @@ -386,7 +431,9 @@ uint8_t oled_max_chars(void); uint8_t oled_max_lines(void); ``` -!> Scrolling and rotation are unsupported on the SH1106. +!> Scrolling is unsupported on the SH1106 and SH1107. + +!> Scrolling does not work properly on the SSD1306 if the display width is smaller than 128. ## SSD1306.h Driver Conversion Guide diff --git a/docs/feature_pointing_device.md b/docs/feature_pointing_device.md index 4da5d64a1a..909eff826d 100644 --- a/docs/feature_pointing_device.md +++ b/docs/feature_pointing_device.md @@ -197,6 +197,24 @@ The Pimoroni Trackball module is a I2C based breakout board with an RGB enable t | `PIMORONI_TRACKBALL_DEBOUNCE_ |
