Native color format rgb565 is compatible with ILI9341
#### ** ILI9486 **
Enabling support for the ILI9486 in Quantum Painter is done by adding the following to `rules.mk`:
```make
QUANTUM_PAINTER_ENABLE = yes
QUANTUM_PAINTER_DRIVERS += ili9486_spi
```
Creating a ILI9486 device in firmware can then be done with the following API:
```c
painter_device_t qp_ili9486_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);
```
There's another variant for this [Waveshare module](https://www.waveshare.com/wiki/3.5inch_TFT_Touch_Shield), because it has a quirky SPI->Parallel converter. You can create it with:
```c
painter_device_t qp_ili9486_make_spi_waveshare_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 these functions 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 ILI9486_NUM_DEVICES 3
```
