+### ST7735 :id=qp-driver-st7735
+
+Enabling support for the ST7735 in Quantum Painter is done by adding the following to `rules.mk`:
+
+```make
+QUANTUM_PAINTER_ENABLE = yes
+QUANTUM_PAINTER_DRIVERS = st7735_spi
+```
+
+Creating a ST7735 device in firmware can then be done with the following API:
+
+```c
+painter_device_t qp_st7735_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_st7735_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 ST7735_NUM_DEVICES 3
+```
