# 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.
