|

* The STM32L496-DISCO board has a 240 x 240 pixel TFT color LCD display with
|
||||
* ST7789 driver IC using MCU 8080 16-bit parallel interface (default with
|
||||
* SB14=ON and SB15=OFF). SB14 and SB15 control the ST7789 `IM0` signal.
|
||||
* With SB14=OFF and SB15=ON, the MCU 8080 8-bit parallel interface is enabled.
|
||||
*
|
||||
* For the `LCD_*` pins the identifiers are used as given in the [schematic]
|
||||
* (https://www.st.com/resource/en/schematic_pack/mb1261-l496g-b06-schematic.pdf).
|
||||
*
|
||||
* The LCD display has to switched on explicitly by activating VDD_LCD using
|
||||
* the LOW active `LD_PWR_ON` signal.
|
||||
*
|
||||
* @note The `LCD_RESET` signal is provided by the MFX GPIO2 pin. Since the MFX
|
||||
* is not yet supported, the `LCD_RESET` signal cannot be used by the display
|
||||
* driver. However, since the `LCD_RESET` signal is pulled up and the MFX GPIO2
|
||||
* pin is configured as a floating input by default, the driver will work
|
||||
* without MFX support and the `LCD_RESET` signal.
