# Usage
To use this driver:
1. Add in your `gfxconf.h`:
a) `#define GFX_USE_GDISP GFXON`
2. To your makefile add the following lines:
```
include $(GFXLIB)/gfx.mk
include $(GFXLIB)/drivers/gdisp/STM32LTDC/driver.mk
```
3. Add a `board_STM32LTDC.h` to you project directory (or board directory)
based on one of the templates.
# 2nd layer
Two things need to happen in order to use the 2nd LTDC layer:
- Set `LTDC_USE_2ND_LAYER` to `GFXON` in the board file.
- Set `GDISP_TOTAL_DISPLAYS` to `2` in `gfxconf.h`.
The 2nd layer is exposed as a separate display. Use `gdispGetDisplay()` to retrieve the individual layers.
For more information, see:
