### ILI9488 :id=qp-driver-ili9488
Enabling support for the ILI9488 in Quantum Painter is done by adding the following to `rules.mk`:
```make
QUANTUM_PAINTER_ENABLE = yes
QUANTUM_PAINTER_DRIVERS = ili9488_spi
```
Creating a ILI9488 device in firmware can then be done with the following API:
```c
painter_device_t qp_ili9488_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_ili9488_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 ILI9488_NUM_DEVICES 3
```

!> Some ST7789 devices are known to have different drawing offsets -- despite being a 240x320 pixel display controller internally, some display panels are only 240x240, or smaller. These may require an offset to be applied; see `qp_set_viewport_offsets` above for information on how to override the offsets if they aren't correctly rendered.
