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 be 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.
