+
+### ** Common: Surfaces **
+
+Quantum Painter has surface drivers which are able to target a buffer in RAM. In general, surfaces keep track of the "dirty" region -- the area that has been drawn to since the last flush -- so that when transferring to the display they can transfer the minimal amount of data to achieve the end result.
+
+!> These generally require significant amounts of RAM, so at large sizes and/or higher bit depths, they may not be usable on all MCUs.
+
+<!-- tabs:start -->
+
+#### ** RGB565 Surface **
+
+Enabling support for RGB565 surfaces in Quantum Painter is done by adding the following to `rules.mk`:
+
+```make
+QUANTUM_PAINTER_ENABLE = yes
+QUANTUM_PAINTER_DRIVERS += rgb565_surface
+```
+
+Creating a RGB565 surface in firmware can then be done with the following API:
+
+```c
+painter_device_t qp_rgb565_make_surface(uint16_t panel_width, uint16_t panel_height, void *buffer);
+```
+
+The `buffer` is a user-supplied area of memory, and is assumed to be of the size `sizeof(uint16_t) * panel_width * panel_height`.
+
+The device handle returned from the `qp_rgb565_make_surface` function can be used to perform all other drawing operations.
+
+Example:
+
+```c
+static painter_device_t my_surface;
+static uint16_t my_framebuffer[320 * 240]; // Allocate a buffer for a 320x240 RGB565 display
+void keyboard_post_init_kb(void) {
+ my_surface = qp_rgb565_make_surface(320, 240, my_framebuffer);
+ qp_init(my_surface, QP_ROTATION_0);
+}
+```
+
+The maximum number of RGB565 surfaces can be configured by changing the following in your `config.h` (default is 1):
+
+```c
+// 3 surfaces:
+#define RGB565_SURFACE_NUM_DEVICES 3
+```
+
+To transfer the contents of the RGB565 surface to another display, the following API can be invoked:
+
+```c
+bool qp_rgb565_surface_draw(painter_device_t surface, painter_device_t display, uint16_t x, uint16_t y);
+```
+
+The `surface` is the surface to copy out from. The `display` is the target display to draw into. `x` and `y` are the target location to draw the surface pixel data. Under normal circumstances, the location should be consistent, as the dirty region is calculated with respect to the `x` and `y` coordinates -- changing those will result in partial, overlapping draws.
+
+?> Calling `qp_flush()` on the surface resets its dirty region. Copying the surface contents to the display also automatically resets the dirty region.

The `qp_set_viewport_offsets` function can be used to offset all subsequent drawing operations.

-## Quantum Painter Display Drivers :id=quantum-painter-drivers
-
-### Common: Standard TFT (SPI + D/C + RST)
-
-Most TFT display panels use a 5-pin interface -- SPI SCK, SPI MOSI, SPI CS, D/C, and RST pins.
-
-For these displays, QMK's `spi_master` must already be correctly configured for the platform you're building for.
-
-The pin assignments for SPI CS, D/C, and RST are specified during device construction.

-### GC9A01 :id=qp-driver-gc9a01
-
-Enabling support for the GC9A01 in Quantum Painter is done by adding the following to `rules.mk`:
-
-```make
-QUANTUM_PAINTER_ENABLE = yes
-QUANTUM_PAINTER_DRIVERS = gc9a01_spi
-```
-
-Creating a GC9A01 device in firmware can then be done with the following API:
-
-```c
-painter_device_t qp_gc9a01_make_spi_device(uint16_t panel_width, uint16_t panel_height, pin_t chip_select_pin, pin_t dc_pin, pin_t reset_pin, uint16_t spi_divisor, int spi_mode);
-```
-
-The device handle returned from the `qp_gc9a01_make_spi_device` function can be used to perform all other drawing operations.
-
-The maximum number of displays can be configured by changing the following in your `config.h` (default is 1):
-
-```c
-// 3 displays:
-#define GC9A01_NUM_DEVICES 3
